Was wondering if anyone else has a ehiem external hobby pump. I have the 1250 and it has a 3/8" return nozzle on it how do I plumb this to my main tank? I want to get a hole drilled in my main tank for it, but not sure what size I should make the hole for the return in the tank? Thanks for your input in advance!
