I'm trying to get my sump working because I want to add to my stocklist, but I can't get it working properly. First off, I think I have a Tom Aquarium Overflow with an Aqua Lifter AW-20 to help keep syphon going. The intake pump is hooked up to my skimmer. I believe my intake is a Sedra pump. That's working great and my skimmer is working fine, I don't have it hooked to the DT right now, it's just skimming my sump at the moment. Here's where I have problems...i have a rio 2100 return pump that doesn't work anymore for some reason. When it did work it was unreliable loosing pressure all the time. I'm thinking about going with a Danner Mag Drive 5 500 GPH
. Does anyone have a Danner or can someone suggest something reliable? I don't need a strong return because I want the water to spend as much time in sump to get it nice and clean. But I'm not sure how much per hour my intake is bringing in. Also the piping is weak. I have flexible plastic tubing, should I PVC
the woke darn thing? And should I get rid of the type of overflow that I have? I can't find anything about it really. I want to keep the Aqua Lifter and use it as an auto top off. Any and all help will be appreciated. Thank you.
