I just bought a 40g breeder to mod it as a sump. How big should the return section be to prevent the return pump to run dry? The return pump I am planning to use will either be a Ehiem 1060 or 1062. The overflow will essentially by the BeanAnimal style (one 1.5" full siphon, one open channel and one emergency). Thx for any help.
