BioBalls in Sump and is sump working normal in general?
I have no room in my sump to setup BioBalls and allow water from the drains to run over top of them. Would it be helpful to still have them if I keep them in the drain area, since the bioballs float, they still move around, would that be enough, or should I just forget about using them, and go with lava rock/ceramic rings in the drain area? I have 3 gallons of the bio balls already so I figured I would use them. I also have one gallon of CPR BIO-BALE between baffle on each side of the tank. I got 2 foam inserts as well to put after the last baffle before the pump to help with water as well. How much flow should I have in my sump? Mine just seems to trickle? I don't know if that the case or not, pump never run dry. The pump is a MAG 18, with flow open all the way, I am running herbie style drain on each side of the tank with returns come back over the top.
Sorry for all the questions, my tank been cycled for a while now and have bunch fish in it, and now it seems to be doing some type of cycle again, and smells, I have been doing 50% water changes, and the smell gone away, but wondering if my sump was not working as it should or what going on, bit confused. Below is how I reconfigured the sump today, and seems to be working bit better.
