Hey thanks for the info on the tonga rock.I'm learning slowly, just purchased a couple of books to read, but so far havent found one that tells me if i should do a water change before my tank finishes cycling or not.. My tank has been up for 2 anda half weeks now. I only noticed a slight spike in the ammonia the day after adding some additional live rock so i guess it hasnt cycled yet. I have 2 damsels and a banded shrimp in the tank, thanks to some misinformation from a fish store, but so far they are doing ok |
