HOW TO SET UP A TANK, condensed verions (retitled)

--------------------------------------------------------------------------------

Hello im mike and ive just got in the hobbybut have had some minor exposure to it from my 4 yrs of envying myformer roomates 55 gal, so ive started with a 20 gal tall with 25 lbs of agralive bed, 20 lbs of established purple and white live rock, AquaticLife Internal Mini Skimmer 115, Marineland Ml90509 -Jet 400 PRO, Marineland Visi-Therm Deluxe Submersible Heater - 75W. a regular carriage balast that came w tank that has a Coralife T8 Colormax Aquarium Lamp 18 inch, ecoxotic Panorama Pro LED Modules (blue)and 20 gal rodi h2o.....i let that cycle for about two weeks and today i dropped in frags of red zoa, green zoa, and redacted (sp?) mushroom, 25 critters--1 tiny emerald crab, 20 or so snails and hermits, and for giggles two small blue chromis, starting a diet of brine and mysis shrimp.....i think im doing ok, but im a little concerned that there has been sort of a fine "dust" swirling in there making it soewhat not as clearas it was yesterday. Im starting to wonder if my skimmer is optimal right now, or im overreacting to something that should clear up soon ....edit...one of the live rock i put in today was new coul dit be from that, nad how do i elimanate the skimmer as being potentialy running at minimal capacity...also there hasnt been a great ammount of skim or build up yet in collection cup, some, but not much. maybe not enough bio load yet?

anyway, any direction would be most welcome, sorry if this is to detailed for this spot but i truly am a begginer.
 
Have you tested your water since setting it up? Have you tested it after adding the fish and inverts also? Any algae blooms or diatoms covering your sand or rocks since "cycling" your tank? Did you use any starter bacteria to "seed" the tank?
 
Quick question for those who have had tanks for awhile now. How does one "cycle" a tank? I've searched the forums using the search tool but there seems to be no explination of the process?

I've just started a 30 gallon cube. The salt water has been mixed up for about a week now and I just added live rock today. From what I have read so far it takes 4 weeks for live rock to cycle and only then I can add fish?
 
NarumiHayaashi, if you re-read the first posts of this thread, it is plain to see. But the basic principle is that you are giving your new tank a chance for the bacteria to build up and be able to handle nutrient removal on it's own BEFORE you add nutrient creators like fish and inverts. You will notice that brown film on your rocks, sand and glass as a sign that new chemical reactions are underway, but it doesn't mean that it's complete.

So all you need to do is wait patiently...or, you could add some dead fish/shrimp from the grocery store to help the bacteria along, but not a lot, just a small amount for your sized tank. Allow it to decompose on it's own and start testing your water every couple of days for Nitrate, Nitrite and Ammonia; this will give you the ability to monitor these nutrients rise an fall and thus the end of your cycling once all levels bottom out near undetectable levels for your kits.
 
Absolutely: when reading an INFORMATION thread, start from page one. All the info tends to be clustered at the front.

All I can offer to say to you is Thanks.
I am coming back into the hobby after several years away and I have read these 6 pages 3 times and each time I learn something else
 
Howdy! This is an awesome, informative thread. I have reserected the 55gal my Dad set up 15+ years ago. After reading, I have 2 questions.

1) I have a trickle filter with bio balls. At least until my feet are wet, its going to be a FOWLR tank. Why are bio balls unsuitable for reef? In a different thread, I was told everyone hates on bio balls but the only negative that was brought up was that they need maintenance/cleaning.

2) you mentioned that most marine tanks don't have a cover other than egg crate or something to prevent fish jump, that evaporation is good. I live in Denver where it is very dry, and at least right now in the winter, cold. (house set to 68-70). So without cover my evaporation rate would be very high. Other than for cooling ( and I will be using LEDs ) is there any other reason to leave the tank open, or can I cover it with plexiglass?

Thanks so much!
 
I am very new to the world of salt water aquariums. I started my cycle 2 weeks ago on my fowlr. I noticed I have a lot of air bubbles, why? And how do I get rid of them?
Thanks

My tank: 72 gallon bow front, 100 pounds of sand, 60 pounds of live rock, 10 gallon sump, Berlin protein skimmer, 2 evolution 1400 power heads, led lightening
 
I have questions in regards to cycling and adding some residents?

When to add CUC to the DT during the cycle? tank will be 40gL with at least 10lbs of LR and aragonite (I am planning mostly snails in a fowlr)

When can chaeto be added to the refugium (hob)?

1. if you're going to have corals you need to aim at having either an all-in-one tank---or a sump, skimmer, and good lighting. Your rock and sand take the place of a filter.
a. stony coral and clams: need brighter light, good circulation. For sps (colored sticks) you need high flow and a super skimmer.
b. 'soft' coral is more forgiving, can exist without a skimmer if you don't push it, but it's a good idea to have one.

2. if you're fish-only you can get by with a filter: you have to change it meticulously. Rock and sand will help it out, but are never as strong in the presence of a filter (up and down of food supply as it's cleaned and not) as without one. Still, with big messy eaters, you may need that filter. Putting a little mushroom rock in your tank is still a good idea: spread-out mushrooms are an indicator of good water quality. Shriveled mushrooms are an indicator of trouble---far ahead of when your fish will announce it by showing distress. Gives you a heads-up visual test and helps.

3. TO START: get aragonite substrate, 1 lb per gallon. Dry is as effective as 'live sand'. It all gets live eventually. I prefer medium grade, which does not blow about in a strong current: not as pretty as 'fine,' but in a high-flow tank, it stays put. Do not get crushed shell or coral---it has problems. I lay down eggcrate [lighting grid: Lowes] on the bottom to prevent rocks rolling.
a) rock: you need SOME live rock. about 10% live at 1-2 lbs per gallon. Choose really lacy, holey rock. Limestone. Dry rock will turn live. Takes about 12 weeks to cycle as opposed to 4 with all live rock, but will save you enough to afford better lights.
b) wash the sand before using it. Rock goes down first, then sand, then live rock if you only have a little.
c) use ro/di to mix salt with---usually 1/2 cup salt mix per gallon of fresh water. This yields a salinity of 1.024. Keep it there while you cycle: draw a 'fill line' on your sump or tank representing perfect salinity, and 'top off' with fresh ro/di as it evaporates.
d) marine tanks don't have lids as a rule. But a jump screen is a good idea once you get fish. Most will go airborne if frightened. You WANT that evaporation to go on, and the cooling that results. There are so many pumps and bright lights, heat is your enemy.
e) keep your temperature about 80, day and night. This is another reason to have no lid. It's a good thing to run your lights and everything BUT the skimmer, which just has nothing to skim until you have fish.
f) plan a quarantine tank: no rock, sand, no cycle, just bare glass and water and a heater, not even a light. Keep all new fish there for 4 weeks to be sure they don't bring in 'fleas'. Parasites are not nuisances in this hobby: they kill, and they get into your sandbed and reproduce and infest every fish you own. Quarantine is serious business. You can start a fish in qt 4 weeks before you expect your tank to be ready.
g) don't get 'miracle potions' of bacteria and for gosh sake, don't get a fish. You're good just with the natural dieoff from your rock, but if you just have to do something proactive, drop 4 flakes of fishfood in a day until you spot ammonia in your daily tests. Keep feeding imaginary fish daily---and 5 days after you fail to provoke ammonia, you are cycled.
h) expect sheets and waves of green hair algae. Phosphate is the cause, and rock and sand come in with a load of it. So does conditioned tapwater, which is why we suggest, nay, plead with you to use ro or ro/di water. You can get ro from your supermarket kiosk. Owning your own ro/di filter is a Good Idea, and you reach the breakeven point in about a year for a 50 gallon tank.
i) btw, the optimum tank size is 50-100 gallons for a beginner. The smaller or the larger the tank, the bigger the problems. For little tanks, it's like driving a sports car---every twitch produces a huge, often bad, result. For big tanks---everything is huge, heavy, and spendy, and water changes are (at 10% per week) both spendy and heavy to lift. The 50-100 tanks are middle of the road, let you keep blennies and gobies (50) or some tangs (100). Be sure, however, if the big fish (tangs and angels) are your love, you spring for the big and Lonnnnnnnnnnng tank. These are swimmers, high speed, and they need it, the way you can't keep a race horse in a little pen.
j) read the sticky on acclimation: a refractometer is a very good investment---it saves fish. If you are within .002 salinity, between the fish's bag and your qt tank, you don't drip acclimate: just put them in---and if you've prepared by finding out the salinity the fish's bag will be---you can prepare that tank so there is NO drip acclimation---which can kill. The explanation is in that sticky.
k)don't dose any chemical you don't have a test for.
l) if you have a salinity accident, correct it slowly, no more than .002 per hour. Topping off with salt water is a good way to raise it, just in the natural evaporation.
m) never trust a heater or thermometer. Use 2 thermometers, and touch the glass often in passing, just to be sure.
n) clowns are interesting fish, but they are aggressive---some more than others. The redder, the more so. And you should NOT get an anemone until your tank is about a year mature. Give your clowns a nice hardy coral to wallow in and they'll be quite as happy. Anemones are difficult, delicate, and in the hands of a new hobbyist, downright dangerous to the rest of the tank.

Most of all-----come here and ask BEFORE you do something, and NEVER impulse-buy a fish or invert. It mostly ends badly, and sometimes takes out a tank in the process. There's nothing your fish store gets that they won't get again, especially if you ask. Don't buy 'rare' things: translation: it usually doesn't thrive and often dies. Don't buy exotic fish. Same reason. These aren't decorator items. Get tough little guys that eat plain food and can put up with a few beginner mistakes. Leave room in your tank for them to grow. Many fish we keep reach a foot in length: know how big your fish will grow, and pick what will be happy in your tank.

Good luck---and always ask. There's a 'why' for all of this. It's better to know one sure way that works and get experience at this---and then you can try new theories. Don't get in a hurry, don't take chances, and don't shortcut. If there were a faster way, I assure you, everybody would do it. This is a hobby that's been around for more than a hundred years, and people have tried almost everything, finding many things that don't work. We've sifted out the things that do work, and if you can just get through your first year, you'll find this all makes basic good sense.

This might be rudimentary question, but I am setting up my first tank. I am wanting to use live sand, specifically Arag Alive. Common sense is telling my not to wash the sand as suggested above, because that would be defeating the purpose of buying live sand. Is that right?
 
Thanks for that nice, concise summary. Very useful. A couple of questions.
1. quaranteen tank won't have any biological filtration goin on and a fish in there for 4 wks. I have a 6 gallon Fluval I'll be using. I'm assuming I should run it's mechanical filter in addition to the heater. Is this right? Also wondering about water changes. Is it necessary in this tank if the fish is only in there for 4 wks and I have the mechanical filter going? If the fish graduates to the main tank with no evidence of disease or parasites, can I use the same water for the next guy? Do you quaranteen snails and such?

2. Not clear on why no plants in the main tank. I won't have a refugium tank, not doable and am not clear why maybe sea grass and some of the less invasive macro algae wouldn't be appropriate to have in the tank. You mentioned blocking light as they grow. Is there other reasons? If you were add plants, at what point would you add them?

3. When are you supposed to add clean up crew?

4. While the tank is cycling do you just leave it alone aside from topping off and maintaining the appropriate salinity? No water changes?

Sorry for the questions that are probably really boring and obvious, but I'm close to getting started and have been reading and reading and reading and these little details are bothering me. I don't want to fail.
 
Sk8er,

Thank you for all the useful info.

Question: How big of a lr should I buy for my 29g Oceanic Cube (I think the actual water volume is 22 -- 26, not sure)? From what I see, rock is being sold per pound; is there a rule of thumb suggesting how many pounds of rock (and sand) is appropriate per gallon? Thank you!
