Little Giant return pump question

[banditpowdercoat]

Personally, if staying with LG, then the 2 should be plenty IMO. Will be approx 600GPH which should be lots. Not familliar with the Eshoppe stuff, but usually rule of thumb I have been told is 10x sump volume for turnover. so 30g sump 300gph flow rate through it. Now it all varys to setup, drains etc. My sump could handle my LG 4 at wide open, but my drains can't fully. Also, I belive, slower througyh sump, more contact time for skimmer and anything in your refugeum section or what have you
