I'm running a 125g for a pair of black nasties. I was given a sump system that needs work and idk what I'm doing really. I also have the opportunity to get a fx6 for $175.
My question is do I just go get the fx6 or fix the sump and use that? Or should I use both? I also have a sunsun hw304b. Should I use that as well?
Here are pics of the sump and the overflow. If I should use it, please tell me everything I need to do/fix to get it up and running. Any help is greatly appreciated:
