I have a DIY fluid bed sump with a cubic foot of K1 media and a marinepure ceramic brick coming for bio filtration, but to fluidize the bed I used powerheads that suck water from my return pump chamber to keep them from clogging with K1. Is there any disadvantage of double filtering my water like this as it passes through? Tank is a 125 and sump its 40b. 1400GPH return pump at 3 feet.
