Jennifer V Posted February 16, 2022 Share Posted February 16, 2022 Hi Nerms! I feel silly asking, but is it ok to add BB after water changes if the tank is cycled and I haven't made any changes e.g. adding new fish, adding meds? My tank has been set up for more than a year and is very stable but I thought I read somewhere that you could/should add BB with water changes. I have a large bioload with four messy pea puffers in my 10g so I do ~50 percent water changes every week to keep the nitrates down around 40 ppm and have always added 1/4 cup Fritz Zyme 7 after each water change. Am I wasting product or should I just follow the "if it ain't broke ... " adage? Link to comment Share on other sites More sharing options...
