Filter Problems.

Filter clogging brown water high nitrates.

I have recently had an issue with water quality. My 75 gallon aquarium bio load is to great for my filter to handle resulting in brown water. My filter would clog up within a day causing my flow to go from 560 gph to below 100 gph within one day. My nitrates were also creeping up.

My fix: Replaced the PVC canister filter head with a trickle filter box I made from a plastic container. So the outcome is increased surface area so the filter wont clog and no back pressure on the water pump which maintains the 640 gph. So far it works out great for what it is.
