I have completed my fuge for my 29 gal. reef. It is an old crappy 29 gal. that i had an oscar in. I made three sections, protein skimming in the first, then come s the fuge part about 14 gallons worth, with a 1 inch pleneum, egg crate, CC and then some Agra-Alive Reef sand, 4 inch sand bed, then the next chamber drops down and i have my return pump. I wanted to know if i need to cycle the H2O in the fuge, total H2O volume is about 20 extra gallons. My main tank has been up and running since Aug of 2003, Ammo 0, pH 8.3, Nitrite 0, Nitrate 20 ppm, SG 1.024, Ca++ 400, KH 10, Temp 79, of the main tank. The fuge is showing zero ammo, via a sea chem sticker. Thanks guys, i will try and post some pics, but i dono how to decrease the pixles on my camera. :idea: :twisted: :roll:
