Just upgraded to a FX4. I know every ones bio load is different, but what kind of expectancy should I have for time between Filter cleanings? I've heard everything from 2 weeks to 6 months. The FX4 appears to have significant more filter area than my previous Aquatop CF500UV. I cleaned it about once every three weeks to a month. I probably could have stretched that out further I'm running a 75 gal heavily planted, heavy livestock.
Whats your opinion? More often lighter cleanings or let it reach near capacity?
