If I clean my filter media with my tank water will I ruin my bacteria beds? I have bio balls ad scrubbies. whats the best way to clean it without killing my bacteria? is their enough bacteria in my gravel so I would'nt have to worry about it. my tanks been set up for a year now but i noticed the flow rate decreased a little in my wet dry. what should i do?
with Pharaoh, you'll get the majority cleaned. Or route the sump return to a drain and just stir the bio-balls a little (watch the water level in the tank!). All you want to do is remove the detritus unless you have a problem you haven't told us about.
