What is a good reliable return pump

[Gizmo]

I like Quietones better than ehiem. I find Ehiem's plastic brittle and have not had success with 2 of their pumps. Quietone had great output and doens't use a lot of energy. They can be both submerged or inline. I've used them for probably 5 years now and I give it ***** stars cause its inexpensive compared to other pumps. I've never used Mag, but heard good things

Hi. Thanks for the advice so far, i am going for the herbie style overflow, i got some great advice on another thread on the drilling and overflow for that :O) When i buy the pump how much of a flow rate, or how many GPH should i be looking for for a 72 gallon? Thats where i get the most lost
