I have a home made sump with drop trays. There are several dead spots that don't get any water dripping through. My question is. Am I better off removing the drip trays and filling the sump near full to cover the bio balls or leaving as is. I'm in the process of switching to ceramic rings but still have a long way to go. 90 gallon sump, 350 gallon tank, 15 gallons of bio balls and over 10 liters of ceramic at the moment. Pumps push about 3000GPH. THANKS
