Okay real quick im not a newb to tanks and I know what each chemical does to your fish so I don't need responses on that.
My question is I have a fluval 205 that I use strictly for bio filter, however, my nitrates have gotten high and daily gravel cleans and pwc have do not seem to lower it much.
It was my understanding that you don't clean the biofilters that much otherwise you kill the beneficial bacteria that is supposed to control nitrates. Could my spike in nitrates be from a dirty biofilter? If so what is the best way to clean it without destroying beneficial bacteria. Can I use filtered water from my sink filter? I've tried the bucket of tank water and ut just doesn't do a good job.
