As I start the build out for the 125 agressive, I'm decoddec to re do my qt strategy. I can't decide. A 29 and stand? 40 breeder and stand 55 and stand I have the 55 but no stand, and I could get rid of it / trade it for something and get a 40 or 29 setup. Was goibg to be my sump but I'm gunna do a stock tank sump instead. Thoughts?
