Subj : first filter change To : All From : Ruprecte Date : Mon Jul 07 2003 10:20 pm Hey all, its been six weeks and I think its time that I change out my media. My question is this: should I rub off some of the bacteria from the old media onto the new one before replacing, or should there be enough beneficial bacteria already existing within the tank that will collonize on the new media. Im using a aqua tech 10-20 power filter in a 29g tank. The tank has been up and running for six weeks now and somehow is still reading nitrate levels at being 20-30. Im assuming that this is due to the extended time that Ive let the original media stay in there, to me this seems to be the only possible reason that the levels are so high, ammonia is low-close to non-existant and there are five large plants+12 fish that have all been in there for the last six weeks..no new additions and no losses.Thanks for any imput.-Brian -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 80,000 Newsgroups - 16 Different Servers! =----- --- 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 7/7/03 9:20:04 PM * Origin: MoonDog BBS, Brooklyn,NY, 718 692-2498, 1:278/230 (1:278/230) .
