d) Will you have an ATO system?

I'm sure there are even more questions, but once you answer these, it will help you figure out size.

May we ask.. Which do you prefer- in-sump or external?

If by fuge you mean refuge for fish to get away from predators, no, we will probably not have the external room for a refuge.

That is interesting.. how much backflow is normal? and should the sump be run at a level lower than the expected overflow?

I will have to find out what a ATO is.. lol.
