Sorry....it is a 75 gallon reef tank(with live sand). We have live sand and we have the following fish/rocks,etc in the tank:
1-cleaner shrimp; 1-coral banded shrimp; 1-coral beauty angle; 1-pink skunk clown; 1-bulb anemone; 1-emerald crab; 1-sand sifter star; 2-brittle stars; 5-damsels; 1-basslet; 2-corals; 2-featherdusters; 5-gorgonia; 1-lettuce nudibranch, and about 100 lbs of live rock. There are several species of green aquatic plants as well. Nitrates and Ammonia and pH all fine. Seems like thrid stage of cycle is the problem with Nitrates at 60-80. Will do partial water change tomorrow. Anything else? More plants. Afraid of losing coral and anemone at thes nitrate levels.
