OK........It's that time of year to clean up all your bio filtration to get ready for winter. .... Cleaned up the original filters and all the extra bio material in my Savio skimmer and Savio waterfall. Myself here in Zone 7 have about 3 weeks until a killing frost, so my multitude of plants will keep the ammonia and nitrates in check until the bacteria gets back going in my filters. Only feeding Cheerios now, no high protein food, I really don't think the fish would be be harmed if we cut off feeding now....... It's just a feel good thing for us...... Only chore left for me is cutting down the jungle...... Uggh
