I was hoping to get a little advice as now that I finished my sump I have a concern. I re-purposed an old bio-ball filter and then drilled a hole through it linking it to my sump return pump chamber. After watching it and the water rising I have become concerned that it could easily clog and flood the house. If it clogged the water would keep coming in via the manifold and over fill the fuge area. Is there any mods that you can think of that might eliminate the risk? I also want this as a cope-pod farm. My hope was that they would enjoy their secure location overpopulate and flood over the bulkhead to some hungry fish. I prefer mechanical to electrical fail safes and I was thinking of adding a second bulk head perhaps lower and then screening off the chaeto.
