New to hobby - need advice on pump size

[NaClH20]

Hello All,

I am new to the hobby and am working on a project tank. I bought a used 90 gallon tank setup that came with a 30 gallon sump. It has an overflow in the middle of the tank with 1.25" drain and 1.25" (internal diameter) return holes already drilled with bulkheads installed but little else.

Question: What size pump should I get for a 90 gallon.

I want to do a saltwater fish tank and might end up dabbling in some coral later on. I have read a lot about pumps and tank water turnover. I have read about people going from 5x an hour turnover to 20x an hour turnover.

What would the group recommend and why? I am looking for flow capacity and brand names for the pump.

The project tank and sump below:


90 Gallon acrylic with canopy etc - Going to be cleaning it up a bunch and sanding and buffing out the scratches.



30 gallon sump after about 8 hours soaking in vinegar and a lot of scrubbing.

I use an eheim compact plus 3000 on my 90g. I use the eheim compact plus pumps on 3 of my tanks. They have great head pressure, delivers right on flow rate up to 5-6 feet; and has the eheim reputation. Can't beat the price, they are adjustable and there's a 5000 that's more powerful,

Thanks for the reply. Have you ever used a DC pump? I am trying to make the tank as quiet as possible as it will be in an office area.

I've never used a dc pump, these eheim pumps are dead silent.
