I have tried everything and the struggle is real. I have 4 ACFs, small right now so they're in a 20 gallon long but they are SO dirty, despite daily vacuuming & weekly water changes, I cannot keep the water clear. I was wondering if anyone had any suggestions. I've tried sponge filters, can't afford a canister filter (& they look kind of difficult) & have 2 hob
reptofilters that I like, as they're quiet & small. What if I used a filter sponge in the bottom of the filter, then some aquarium food & bio media on top. Would that help keep the water clearer, is there a better solution, or am I destined to have constant cloudy water?
