I bought a 65 gallon megaflow overflow tank including the megaflow 3 wet/dry filter. The site says the over flow runs 600 GPH rate and that I should use a pump that can return 2400 GPH

Is this right? Wouldn't it push too much water more then its draining down into the sump? I'm trying to find return pumps, please help and educate me on what kind of pumps I should use.

Thank you, Andrew

Anyone please?

A sump pump system is commonly used for several tanks.

IE
1 2 3
-------- -------- --------
\ | /

|____________| (sump)

And with several tanks, all dumping into the sump you would need a larger pump to pump the water back into the tanks. IE a 2400 gph pump. But quite often its gallons in = gallons out.

Are you sure you're reading the instructions correctly?

i was told that you should use the water pump that is 5 x your tank volume. 2400 gph is a lot of water turnaround for a 65 gallon tank

Well I can understand the system. But the Sump adds water to the entire system, but will his outflow from the tank be able to drain that much water that fast.

For a 65g I'd use maybe a 200gph pump. Since it isn't over kill. What size is your sump?

The sump size is 25.5 long 13.75 wide and 17 inches high.

Allglassaquarium(s).com in aquariums you can select megaflow aqauariums.

And it will say water will flow in sump 600 GPH and u will need to pump 2400 GPH from a 5 foot head. I was thinkin it was too much.

I bought this sump from a LFS that is going out of business and cost me 200 for everything and including pump. He said I will only need a pump and can push 365 GPH.

I'm getting so confused, I want good current in the tank but not too powerful to take all the water out the sump.

Thank you for the help,

Well the way the systems work is as they pump water into the tank, water should be also taken out of the tank if it has constant flow. Is your tank Bottom drilled or Side wall drilled ?? Either will work fine..

The bottom drilled tanks make it easier to think of once its starting to get assembled. The Out pipe inside the tank sets the max water level, obviously this needs to be below the top of the tank, suggested 2 inches below is a safe amount.

The second pipe is the inflow.

I think you have a different sump system then what's in my head. But w/e.

If your tank is drilled, you can only use a pipe and bulkhead fittings that fit your tank.







But on second thought... sumps use gravity to drain the tank... unless your using 2 pumps for your tank 1 in, 1 out; Which is over kill. Can you take some pictures of your tank, and sump system an the pump that you bought as well. It'll help me to explain and understand whats going on.
