Cool thanks for the heads up B. I need to double check the AZNO3 bottle when i get home, there were two chemicals i was treating the tank at one time, that and some ick medicine (caused by stress due to the high nitrates) one of the two medicines said the skimmer needed to be off while treating the tank, so i hope its not the Nitrate bottle. I will have to check tonight. Feeding is done once a day, the eel gets a piece of shrimp that he eats whole, the puffer get about three krill, small scallop and small silverside, the wrasse (too fast to take a pic with my Sony Cybershot) gets about 4-5 sticks of compressed cichlid food and the lionfish gets 3-4 big silversides and the rest of the shrimp. I mean the puffer and wrasse make a mess, but everyone else eats their food whole so there is little mess floating around the tank.
