My scenario:
Started my 34 gallon Red Sea Max on 12/19/07. Live sand, RO water (with a little Prime, because I'm paranoid about chloramine), salt, and buffer. Four damselfish are struggling, but since my diatom bloom is receding, they are much better. They had a couple days of labored breathing while staying on the bottom of the tank after being happy for about a week and a half. Now they are swimming around again, so I added some blue legged hermits and an emerald crab.
I brought back some Haitian live rock from my trip down in south Florida, and it has been curing 1 week.
My curing method for ~50 lbs:
Day 1 - after scrubbing off the crud, I put it in a 25 gallon tub with salt + 20 gallons RO water + buffer (I don't listen to the complete darkness rule; it gets ambient light from old T5 fluoros about 8 feet away - I think I'm safe).
Day 3 - another diligent scrubbing with a toothbrush, complete water change, same combo, added heater set at 78F
Day 5 - some scrubbing, complete water change, same combo
Day 7 - complete water change, same combo
Seems to be working alright. It's getting less and less smelly as time goes by. Luckily I work at a LFS and can cure it there, right next to the RO unit, and while on the clock to boot.
Anyway, the rock still smells kind of funky. Definitely not something I want to toss in my tank immediately. Or is it? I have read that cycling a tank with uncured live rock is a way to go, and can be more beneficial in the long run, but take about a month longer than a "normal cycle". But since I added the sand the water first, I'm afraid the rock will let off too many nutrients if I were to have added it at say a two-week hash mark. I know that those nutrients can get deep into the sandbed, causing trouble down the road. But would it be at all beneficial to add my rock after about two weeks of curing and finish the job in the tank? Or fully cure the rock for 3-4 weeks, then add it to the tank?
I'm just debating on whether or not it's worth the ammonia spike that will accompany it. Will this set me back, or possibly move me forward?
I'm just looking for opinions.
