new seahorse tank build, and new to RC

hi all, i am new to RC and have been cruising different forums (nanos, seahorses and the macro algae ones to be specific). i just got done reading fishymans thread on a new tank build and thought i would share my build, all advice and constructive criticism will be GREATLY appreciated.

i have been reading a basic book on seahorses, and have been messing around with a 12g nano cube for the past couple years. i have had a massive growth of macro algae (feather and bubble or "grape") in there about 2mos. back. it looks awesome and got me reinterested in the hobby. since its outbreak i have added a new clean up crew (over the summer it dwindled down to one astrea snail, a turban snail, a fighting conch, hundreds of bristleworms and tons of tiny crustaceans).

someone at a lfs told me that i had to change my sand since it is only good for 18mos.?(which i later learned might not have been needed). anyway a few days back i changed the sand bed....what a chore and mess! and cost me the life of my arrow crab...... i also pulled out the rocks that had the calupera on it, added more live rock and then put the rock with the macros on it back in but separate from the main stack of rock..... (i know i am rambling on but i will get to the seahorse part in one second)..... yesterday i was snowed in and messing around looking at the macro algae forum (oh what trouble could i get into stranded at my house all day....) and saw an awesome planted tank. i had to have one!! and since i have wanted a seahorse tank for years maybe i would try to set it up to kill two birds with one stone. i have a 60 gallon tank in a cabinet that was my original idea for a seahorse tank but i knew that i couldnt afford to set it up correctly now, and plus i am thinking of someday turning that into a strictly coral tank......man this stuff is addicting.......OR i could set it up as a seahorse tank and the tank i am about to describe could someday be my quarantine tank.....i should have one any way right?

so how could i set up a tank cheaply to keep me out of the doghouse with my wife who told me to stay away from the my lfs for awhile..... i had 10lbs of live sand left over and a few pieces of live rock with macros growing on it from the sand change on monday that wouldnt fit back in. i went in my basement and started looking at all the old fish tanks and equipment i had stored down there from my days of doing freshwater. it was like xmas....i found a 20 gallon acrylic "sea clear" tank that i forgot i was given about 10yrs ago! i looked around and found two HOB filters, the easiest one to clean up was an aquaclear 300. i spent the day yesterday cleaning and setting up my new seahorse tank.

the tank is a bit scratched but what the heck, i put the live sand in and then washed the old sand i had pulled out of the 12g nano with real hot water (since i guess it didnt need to be changed and was still good). it looks the same as the new bag i bought which is carib seas agri alive "bahamas oolite". it gave me about 1" of sand bed. since i was out of drinking water (we get 5g jugs of water that i have been using in the 12g nano for 2 yrs) i ran to the store and bought purified water (RO with minerals added- potassium bicarbonate, calcium chloride, and magnesium chloride, is this all good?) i added the water and ran the filter, which leaked due to a bad o-ring....damn! i ran back to town and hit the hardware store (my 3 lfs i go to are at least 1hour away and with blizzard conditions the 2 mile drive to town was an adventure!! ) and bought an o ring and since i didnt have a sponge insert for the HOB filter and can be impatient sometimes...i bought a culligan water filter cartridge that was a tube of wound polypropylene fiber. i cut this off and took a big pile and stuffed it in the filter chamber along with a carbon bag i found for it. it really cleaned the water nice! but i will get a sponge for it today.

the wife wasnt too thrilled when she got home to see that not only did i not wash the dishes but that i had set up "another tank"....."but honey it didnt cost anything....well the o ring,water and filter....but lets not quibble over small details.....and you have always been real supportive of the seahorse idea..." i also moved her printer and scanner to set up my new tank..."i think they look lyin on the floor sweetheart!....." . if i open the blinds in the morning i get about 2 hrs of sunlight hitting both tanks with no noticeable heat rise.

i am not patient usually BUT i have raised reptiles for many years and succesfully bred many species so i can force myself when needed to proceed slowly and i know seahorses will be a challenge. i am going to sign up at seahorse.org later today and continue my research here, there and other sources.

my desire is to get my live rock (not too much... my goal was to have only the back half of the sand covered) and put my macros in there and let the tank cycle (will that hurt my macros?). i would like to get a cleanup crew and i was really hoping to put in some sand sifting stars, i just like them, but what are your thoughts. if i wanted to plant eel grass i would probably need to go with a dsb but without an undergravel filter would that be dangerous, due to anaroebic bacteria?

my thought for a clean up crew was going to be 10 nasirius snails, a couple turbo snails, a few astrias and turbans, maybe the two 2" long tonga conchs i put in the 12 nano that i think was a mistake (i read that the fighting conch in there was pushing the limit and now regret buying them....but not really they are cool). and then of course some tiny hermits and all the tiny crustaceans and bristleworms that will be in there from the live rock. fianlly i would like to add a couple tiny bottom dwelling fish like gobies or blennies assuming they are SH safe.

i have not decided on a particular species but know it will be captive bred and one that eats frozen food which will limit my choices. the room does get cooler than the rest of the house in the winter so i could get a species that would benefit from a winter cool down. in the summer i would say it doesnt get warmer than 77 with the a/c that we run all the time for the fur people (dogs) that stay home while my wife and work to support their life...haha.

i plan on buying 2 50watt heaters with guards since i read that on fishymans thread. i will find some live rock and probably buy it on line... with freezing temps though will it completely kill everything on the rock or do they ship with heat packs? also i wonder if the shipping charges will just bring the total price up to the higher price i will pay by buying it locally....i do believe in supporting local buisnesses...(a constant struggle for me ..save money or support local busness?) i fall somewhere in the middle.

the light in the hood is a 15" 14watter...man put the sunglasses on!!....i will tie it to my bumper and drag it to the lfs today.....i will not put corals in as i have the nano and other tanks (i think the big one is a 75 gallon.....man o man i could get in some trouble with that one!!yee haw!!) in the basement....man i should never had gone down there. but i do want the the algae to grow and the SH to look good. the current macros grew with the 24watt compact lite supplied with the nano, actually it was the same bulb that we had in there for 2 yrs....you mean they dont last that long??? i will research and take your advice on lites.

ok i better run, if you read this far, thanks, i know i am "wordy" t say the least...my buddy calls me "captain long wind". i look forward to being apart of this forum and glad i found it. thanks, john
 
Okay, I'll just address a few things for now.
77 is a little high for tropical seahorses, you want to keep your temps around 72-74 for tropical seahorses. Subtropical and temperate you'd have to go lower, into the 60s.
There aren't any tropical seahorses that would really do well in a 20 gallon. I'd go with a minimum of 25 gallons for a single pair of tropical seahorses and a water depth of 18", which means with a 1 inch sandbed and the fact that tanks don't get filled flush to the rim, a minimum tank height of 20".
Good seahorses to start with are erectus, kuda, or reidi, and after everything I've read on forums about die-off and disease from mixing species (each species carries its own dormant strains of diseases that other species aren't immune to), I would definately pick one species and stick with it. There are some threads about people's experiences with mixing species on seahorse.org if you want to research it for yourself.
You don't need too much light for a seahorse tank, even with macros. I have 48 watts of PC lighting right now. Also, I've never heard of replacing a sandbed after 18 months, for a DSB that could be dangerous.
If you buy LR online, you have to take into account that even with fully cured LR, there will be die-off. I like to buy my LR from locals through saltwater forums and craigslist, that way it is fully cured, there's no shipping, and its cheaper.
 
thanks ann, i ended up buying some liverock yesterday at my lfs, he had some new rock in and it looked real good. i like supporting local shops like i said so at 6.50 a pound i think it was ok plus i got to pick it out. i would only keep one species, and will figure out which one is the best for my conditions. i am in no rush and will proceed slowly. i put a few snails and hermits in the tank last nite and planted a bunch of the macros. i will eventually be setting up one of my bigger tanks, but i want to get this one going and give it a try, and like i said it could be part of a bigger system some day or a quarantine tank. my working on this one and talking to a bunch of you on the forum will help me hone this tank, LEARN, and get ideas for my final big set up. i wont put SH in until it is all set up and cycled and stable. i am thinking this spring or summer. are there SH that are in the tropics that live in sun warmed shallows or are most of them seeking deeper cooler water? also i put 12 lbs of live rock in this 20, i was told or read that the 1lb per gallon is not a must. thanks, john
 
there is so much info out there and i will be taking it in as best i can, but i read last nite in a book (Seahorses,Frank Indivglio, 2002) that you can keep 3 pairs of dwarf seahorses in a 15 gallon tank? i am fully aware that just because something is in a book doesnt mean its true, i have found this to be true in my other animal raising hobbies (pheasants,parrots, and definately reptiles). they (dwarfs) are associated with sea grass beds and shallow tropical areas, and this is how i was going to set up this tank. i am not sure of the temps in that room during the summer, i will have to see. i have seen on a couple other threads and in an article in TFH that others are keeping some tropical species at temps approaching the 80's. my other two tanks are 55 gallon (4ft by 15 by 16). i will move the empty one up into my office soon so i can stare at it and plan my future tank, i think the jungle one will stay that way, i just need to get it going again.
 
6 dwarf seahorses in a 15 gallon will be difficult. You would actually want to put a lot more dwarf seahorses than that in a 15 gallon. Dwarves are about as big as your thumbnail, and usually require a high stocking density, otherwise feeding density becomes an issue. People usually keep dwarf seahorses in aquariums less than 10 gallons, which makes it very difficult to keep water parameters in check, but it also makes it much easier to find and see your horses, and it allows you to not have to feed enormous ammounts of baby brine shrimp out twice a day. Also, dwarf seahorses require live food, baby brine shrimp, that need to be hatched daily, so they are more of a project than most people are willing to undertake. As for the temperature, I suggest you read the diseases and treatment forum and the emergency forum on seahorse.org to get an idea of the risks of keeping SH at these higher temperatures. And also to get an idea of what taking care of a sick seahorse involves. Higher temperatures are possible, but are risky, and treating a sick seahorse is a very large production that often times includes tube feeding the horse.
 
thanks, yes, the feeding live brine shrimp part was a bit disheartening, that sounds like a lot of work. i have raised fruitflies before for litters of baby jacksons chameleons and it was tiring. also every summer i have litters of snakes that sometimes need extra TLC that take up a ton of time. what about all the little tiny creatures that live in my 12g nano cube, in amongst the macro algae and such? could that be a self sustaining population of live food, or a decent supplement to occasional live brine shrimp? the new tank (20g)is coming along nice and the 4 different types of macro algae are growning nicely. i like the cooler temp idea, if for some reason there is a temporary temp rise it will hopefully still be in an acceptable range. with reptiles we can set up temp gradients that i guess in a fish tank is impossible. i will see how warm the room gets maybe it doesnt get that warm.
 
If you were going to try to feed your dwarf seahorses the copepods in your tank, you would definately need to supplement it. Each dwarf could eat hundreds in a day if that was their only source of nutrition. So, that would probably mean culturing copepods. I suggest you look through the dwarf forum at seahorse.org to try to get an idea of possible foods and nutrition.
 
i will testify that you WILL NOT have to change your sandbed every 18 months. that is rediculous. you should add snails(or whatever is seahorse friendly) that will stir and help clean your sand. just my opinion. p.s. you can go to you local grocery store and by live clams, i have 2 in my 30G hex tank. they stir up the stand.
 
i might have given bad info to the guy at the lfs, i guess some substrates lose their buffering capacity over time and when he asked if i had "xyz" in there i might have said "yeah i think so"...doh! i have aragonite live sand in both tanks now and will never change it again. the nasirius snails and the conches seem to be doing a fine job of turning up the sand.
 
Aragonite sand does very little boffering in a tank. There is no good reason to change your sand.

On seahorses and temperature, anne83 is giving sound advice. I am one of those keeping horses at higher temps, though it is not entirely by choice. If you can, I would keep your temps down below 78F. I keep my tank at around 76 in the winter and would keep it there year round if I could.

If you do this, be very careful!! Usually the clams from the grocery only live a couple of months, and then die and really do a number on your water quality!
 
thanks for all the help, i think i read that clams and scallops would be a bad idea with SH because they could close up on their tails. i got both my tanks set as 76 now. hopefully that room stays cool this summer, we do run our A/C all day since it keeps the house from being too humid as well. i have been looking at the seahorses at Ocean Rider, i will definately go with CB animals, when they list a SH as being 4-5 inches are they talking about a full length with the tail stretched out?

this 20 gallon is going to be my learning platform for keeping macro algae and maybe a pair of small seahorses and then it will become my quarantine tank once i get the 55g set up. i definately believe in the practice of quarantining new arrivals. i guess when it isnt be used for that i could raise some shrimp in there for occasional live food for the SH's.

this 20 gallon has apparently already cycled, it has been just under 2 weeks.

Not likely. It has gone through some initial cycling, but things will continue to change for a while. Much of what goes on with a tanks cycling is not measurable by hobbyist test kits. One of the only indications we have that the tank has not yet settled are changes in algae type.

thanks fred, ok then i will just keep watching and testing it. i had a power outage last nite for 5 hrs before i got home and got my generator going....it took an hour to get it running and string the extension cords to the tanks and down to the reptile room....then the power went on!!!!!!! i was so PO'd. luckily i have the generator but i have to be there to start it.
