Sump Help Please

[Chago09]

Would it be a bad idea to start my FOWLR 150 gallon with a 25 gallon sump???? then in the future I can upgrade easily. Or will a 25 not be worth it at all????

If you can go bigger, do it. But if not then 25 will be fine. But evaporation will kick your butt without a topoff going that small.

I would do a 40 breeder for your sump, imo. The bigger the better.
