My 75g has been cloudy now for about two weeks. I'm stumped on what to do. At first I thought it was the sand and dirt mixture I had so I completely tore it down and put flora max in. Well the flora max was clear for about 3 days and now it's like this. I've tried multiple filter pads from medium to ultra fine. Currently filtering the tank is an emperor 400 and sunsun 304b. This all started when I cleaned my emperor about two weeks ago and put in new filter pads. I have a ton of carbon in my canister so I'm kind of lost. Stock includes 3 JD, 1 geo, 2 Senegals, 1 flowerhorn, 2 yoyos, 1 Siamese algae eater, 3 BN plecos, 1 synodontis eupterus, and a carpintis festae hybrid. I know it's over stocked right now but once the cichlids get bigger they will be moved. No one in this tank is over 5" except one of the Senegals. Not too much aggression either just the JDs and geo. I just want to figure out why it's so cloudy because it's not pleasant at all and it's in one of the main rooms of our house. Water parameters are always great except occasional nitrate. Thank you all.
