uhuru Posted November 25, 2007 Share Posted November 25, 2007 What is the best way to connect two tanks with 1 sump? The tanks will be at different heights and of different volume. Can I use 2 separate return pumps (1 for each tank) or is it better to have 1 return pump split into two lines? Quote Link to comment Share on other sites More sharing options...
ThePremiumAquarium Posted November 25, 2007 Share Posted November 25, 2007 I have 5 tanks plumbed into 2 sumps connected together with 1.5" PVC. I have 3 pumps total, one running to 3 of the tanks from 1 sump and the other 2 running the other 2 tanks from the other sump. Kinda up to you how you want to do it. All depends on how much flow you want in and out of each tank. Hieght of tanks should really make a difference. Just make sure you have enough room in the sump for water in case of a power outage or something like that. Garrett Quote Link to comment Share on other sites More sharing options...
