yeah i never thought about that.. like i said i have a filter in and running and has been running since day one, but my guess is that it still wont stop me from having to do water changes everyday.. which sucks because i dont have the time between school and work to do one EVERY day. ill try my hardest but i will need a few more buckets.. one five gallon isn't the easiest way to do it. im pretty sure i have a 5 in 1 test strip to test the water for now but i dont get paid till thrusday night and friday i have school and work so saturday will be the earliest i can get a test kit, and i would like to pick up some pvc pipe and put in a undergravel filter along with the mechanical filter. from what ive read it really helps with the bacteria growth? then ill pick up some 5 gallon pails and by the time i build the filter and what not the water should be ready for a change, could i possibly do a 100% change? or would that kill all the bacteria?
