Subj : RE: Re: Power filter down To : All From : Mbuna Date : Sun Nov 14 2004 05:20 pm I don't see a realy problem doing this, although curiosity makes me ask why! The problem that I do see is that the canister filter will go anaerobic during the night eating up all the oxygen in the water in that filter. This can cause loss of nitrifying bacteria as well as fluctuations in pH due to the O2 loss. __________________________________________________ Posted via FishGeeks - http://Aquaria.info --- þ RIMEGate(tm)/RGXPost V1.14 at BBSWORLD * Info@bbsworld.com --- * RIMEGate(tm)V10.2áÿ* RelayNet(tm) NNTP Gateway * MoonDog BBS * RgateImp.MoonDog.BBS at 11/14/04 5:20:25 PM * Origin: MoonDog BBS, Brooklyn,NY, 718 692-2498, 1:278/230 (1:278/230) .
