with just the blues the water settled right out after a while. added the jack a couple months ago, and all was well. spiked a little bit but went back down to .25ppm in a couple days. added the royal pleco a few weeks later and again, small spike but went back down. last night my jack looked jet black, tested the water, and again its up to 4 or 5ppm. did a monster water change but what gives? when id di the water change i didnt pull alot of muck or uneaten food from the substrate.
could it be my filters? the two HOBs pads muck up fast, but i dont swish them until they start plugging up and sending water over the overflows. the canister i do only a couple times a year. could the muck in the filters be causing it?
Hi, you say you clean your canister filter every six months that in my opinion is where your problem lies. Canister filters don't remove debris from the tank like a skimmer does in a marine instead it traps it in the filter producing more and more amonia as the debris rots. I clean my filter every 5 days which may be overkill but 1 to 2 weeks is usually reccommended.
