90g return pump

[iluvreef]

I'm setting up an 90g reef tank with a 90g sump. There will be a coast to coast overflow with a dart return pump. Has anyone used this pump on a 90g tank?
Thanks,
Vanessa

Which dart?

I diddn't know there were dfferent models other than the motor. This is an AO Smith. I know thats a lot of flow but I was planning on backing it down just didn't know how far you can on a dart.

Size of pump needs to match size of overflow, not tank size. A lot of flow might be good or bad depending on what you plan on doing with the sump.

Overflow will be a coast to coast with 3- 1 1/2" drain lines Bean system
Thanks

There are charts to match pumps with overflows. Also what are you planning for your sump? If a refugium type that requires low flow you might need to adjust the flow rate to that rather than overflow capacity.
