I bought a piece of live rock yesterday with a small mushroom coral attached to it. It is about 1/2" in diameter. I got it from the lfs who takes my livebearers when they are old enough to sell, so I trust the source, and I assume that it's healthy at this point. I wasn't planning on adding coral to my tank yet, so I'm not sure where to go from here. Tank is 10g, currently has an Aqueon hob filter, more for water movement than anything at this point; 16# Nature's Ocean Bio-Active Reef Substrate mixed with some regular sand; 6-7# of dry live rock which has been in the tank for less than a week. Lights are currently 2 - 15w 6700 CFL bulbs. It's been running for several weeks now, cycling, and the last time I tested the parameters, a few days ago, ammonia was 0, nitrite was coming down but still pretty high, and nitrate was going up. I don't remember the exact numbers, and my journal isn't available at the moment. I'll test again later today and update, but unless things are significantly different today, it's not done cycling yet. Meanwhile, I have this coral attached to a piece of live rock. I left it overnight in it's bag and water from the lfs, hanging in the tank so it gets light and warmth. It's not much water, though. I've got another piece of live rock from the same store in a bucket of saltwater with a heater and water movement. I hadn't put it in the tank yet because I need to break it up first. I could put the new piece in the bucket, but I don't know if the parameters on that water are any better or how they might change before the tank cycle is complete. Although I guess that's really not a problem, because I could do water changes to keep the parameters OK, since I'm not trying to cycle the bucket. Also - specific question re lighting: I will be building a hood that will hold 4 cfls and probably end up with 2 10w 10000K bulbs and 2 10w 50/50 bulbs, for a total of 4w/g, but for the moment what I can do is leave the current bulbs on the tank, which is 3w/g, 6700K; or switch both bulbs for a total of 2w/g, 10,000K; or use one of each, for 15w at 6700 and 10w at 10000. Thoughts? If I put the new piece of lr in the bucket with the other piece, should I move the light to the bucket for the coral? Any suggestions or advice you have would be greatly appreciated. Thank you in advance!
