Hello I was wondering what everyone else thinks is the best pumps to run from these 2. I plan to use 2 return pumps Placed internal to my sump both separately feeding its own return to The tank. Sump will be next to tank on ground and tank is 96x30x24 so not more then 12 ft line to farthest return bulkhead on tank. I do have apex along with all of its modules so this is why I’m considering Cor-20 Bit I have heard mixed reviews on this pump. It would be nice tho cause I would take full advantage of feed switches and ramp up and down profiles which I’m already use to doing. Then I consider vectra m2 because recently also purchased g5 radions and now using mobius and I heard vectra m2 will work almost same as Cor-20 threw apex as vectra threw mobius. The vectra is about 100$ more then Cor-20 which really is not an issue if I choose vectra assuming it’s the better pump of coarse. Well let me know what you guys think and your experiences with either of these pumps for large tank returns
