Return Pump Size

[taichimaster]

I am setting up a 75 gallon tank. I currently have an Eheim 1250. Will this be enough of a pump for my 75gallon? I have a 1" drain and 3/4" return. Should I upgrade to a 1260?

You probably could go as high as the 1262 for around 900gph. Depending on how much head you have it will drop some by the time it get to the outlet. I would keep what you have for now & run it, not so important to have high flow through the sump but to have good flow though the tank as in ph's or closed loop type set-up.

Thanks for the info. that was exactly what I was intending to do. I was planning to use the 1250 so that the flow is decent enough for the skimmer to do its work. I plan on adding 3-4 koralia 3's.
