Hi, i'm johnny i live in humboldt, and have been keeping a reef tank for a whole year now. i have had problems finding info on the bet way to maintain my tankand thought this forum (jarc) would help. i have a 55 gallon w/ an ehiem 2215 canister filter, current nova extreme 4x48 t5ho, no r/o system and a small protein skimmer that is far insufficent. my live stock consist of two true percula clwons, and a blue hippo tang, along with 1 green torch, one multi color frog spawn, and blue striped mushroom and various other small frags.i have maintained by water changes and that is getting expensive. and it isnt keeping my tank as cleanas i thought it would. if anyone has any used reef equip. for sale i would definetly be intrested in buying it. if anyone has any advise or other input feel free to let me know. thanks, jtnjaxn
