Starting off again!

Hi everyone!

Back in '92, I set up a 120 long at the top of the stairway in my ranch home (replacing the ugly iron railing they had installed there). I had that running for three years before we moved, fish only, but no casualties. Everything except the tank was DIY, including the power inverter for 18 hours of tank operation, including lighting. I had auto water changes working with 55 gallon Rubbermaid cans in the basement and used surplus chemical pumps (NOS) to run the sump and water change system. I used standard fluorescent lights back then.

I'm back. I've got a 90 gallon tank that used to be fresh water (for about 9 years) and empty for about four. I've got it up and running for a week now, without a sump, just 2 Magnum 350 canisters, 3 power heads and 2 200W heaters, with a SolarXtreme 48" light (which I really like!).

I used 40 lbs of live sand and 40 lbs of aragonite for the substrate, and I purchased about 70 pounds of live rock from another member. I'm watching the water, and it all looks good so far.

I'm looking at going to a 180 gallon at this point, dividing the kitchen from the sunroom, and I'm starting construction of the stand this week. I will have most of the goodies in the basement.

Couple of questions:

1. If the first thing you put into the tank is live rock and you have excellent calcium, carbonate, and no phosphor and no nitrate, what kind of a cycle can you expect? What should I be looking for as the 90 cycles, and is there a chance of keeping the corals that are on the live rock alive (a few shrooms and some other things).

2. Sunlight. The sunroom is really the only place I can do this. While I can put shades everywhere... how bad is it to have sunlight hitting the tank during the day for 2-3 hours if the temperature is held constant and the water quality is maintained?

I'm sure I'll have more. Thanks for being around, folks!
 
Welcome to URS!! I'm happy to see you made your way here. I'm also looking forward to watching your progress. It seems that you have a few projects that are going to begin unfolding.

Regarding question 2, imo (in my opinion), use that midafternoon natural sunlight for all it's worth. As long as your nitrates (NO3) and phosphates (PO3) are in check, you won't have to worry about nuisance algae.

Will you be running a lit refugium to grow macroalgae?

Be sure to post some pictures here too!
 
well at first you want to make sure your ammonia levels are as close to 0 as possible,then check for nitrites,you will not see a spike of Nitrates until those others cycle out..Then from there it's just try to keep the Nitrates and P04 levels down by water changes and such..I suspect you will get a couple algae blooms wile all this is going on,but it is pretty normal.

.Depending on how good of shape the rock and sand is that you bought,will be how long the cycle will take Just look for the magic numbers :)

Parameter: Reef Aquaria Recommendation:

Calcium 380-450 ppm 420 ppm

Nitrite < 0.2 ppm typically

Nitrate < 0.2 ppm

Alkalinity 2.5-4 meq/L 7-11 dKH

Salinity 35 ppt
sg = 1.026 34-36 ppt
sg = 1.025-1.027

Temperature 76-83° F Variable2
pH 7.8-8.5 OK

8.1-8.3 is better 8.0-8.3 (can be lower or higher in lagoons)
Magnesium 1250-1350 ppm 1280 ppm

Phosphate < 0.03 ppm 0.005 ppm

Ammonia <0.1 ppm

BTW Welcome back..and good luck with your cycle
 
So, the rock came over to my house direct from a tank 15 minutes away. I think it was out of the water with a wet towel over it for all of maybe 30 minutes. It seems very mature, has some coral on it, and a ton of purple shrooms and coralline algae all over it. It's been in there for 3 days now and it seems very happy! All of the corals have come out, and there are feather dusters, etc. Put a couple of peppermint shrimp in today to take care of some pests... They've already found the trouble and are nibbling.

Going to start work on my sump on Wednesday for the big tank, and I might run it with the 90 to test it out. Right now running two canisters with charcoal in themn temporarily. Water still shows no registered phosphates, no nitrates, nice calcium and carbonate. Temp 78. Salinity at 1.026.

Seems like 70 lbs of already cured and very alive rock may prevent a nasty cycle, from what I've been reading.
 
Just throwing this out there but do you plan on this being a reef? If so was there ever copper used when it was fresh water?

welcome!

welcome!

expect a minimal cycle with the rock you've described. I'm a big fan of utilzing natural sunlight in a reef aquarium but until you learn how to control nitrates and phosphates sunshine can cause unwanted algae growth.

I always recommend purchasing a skimmer before lighting so you might want to start researching protein skimmers.
