Yeah Idk what I'm doing wrong right now haha I have a 70 gallon sump with all that in it plus more n jus nope... my tank is crystal clear tho with alot driftwood n black sandMy sump Is DIY, 19 gallon that I run about half full. It is a wet/dry type with 3 stages of mechanical filtration followed by 300 bio balls. There is an airstone in the pump section of the sump. The last time I tested my water parameters (right before a water change), my nitrates were only 5 ppm, 0 ammonia, 0 nitrites
