Hi everybody,
I have a question: my 75G tank is serviced with a 25G sump and I noticed that the water is somehow stagnant in some areas of the sump. Here and there you could see a biofilm on the surface.
My return pump is an ecotech vectra S2, set up at 45%, allowing for 8x exchange with the tank. I was wondering if installing a small powerhead in the sump could be beneficial for the system or if it is right to maintain the current slow flow to optimise filtration.
Thanks
