Pump Question

[richardhmc]

If I am going to use the CPR CS 100 overflow box rated at 800gph, what rate/kind of pump should I get for my sump? My main tank is a 50 gallon.

Thanks

tank probably wont handle any more then a mag 5, never been someone who believes in high tank return rate or sump turn over, thats why i got power heads

 

[richardhmc]

So a mag 5 would be the only pump for my tank and it wont overflow correct?

 

[NYreefNoob]

always can put a ball valve to control flow, you plan to run anything else off it ? u running phos and or carbon reactors ?

 

[richardhmc]

No, only sump. So if I bought a mag 7 then I could just lower the GPH by using a ball valve correct? Won't this cause backing up of water within the hose?

 

[NYreefNoob]

yes you can and no it wont, put the ball valve attached to the pump

You can use a pump that corresponds to the flow of your overflow without fear of a flood (as long as your CPR overflow doesn't lose siphon).

The head pressure from your sump to your tank will also effect the gph of the pump you use. Not knowing how high you're pumping the water up from the sump, I can safely say you can use an 800 gph pump without any problem. You can likely use a 1000 gph pump if you're pumping up 3', have a true union ball valve in the return line, a 90 deg fitting or two, etc.

Actually I am going to get an overflow rated for up to 300GPH.
I will be pumping approximately a little less than 5 feet. So what kind of pump would be good for this 300 GPH overflow?

once again mag 5, you plan to run carbon and or also phosban ? if so and i suggest you do, get a larger pump and make a manifold so you can run all the items off the pump

 

[richardhmc]

Why is phosban and carbon so important? Is it an absolute need in my sump?

 

[masterswimmer]

I liked your plan of running an overflow with 800 gph rather than 300 gph. Even if you run the exact same amount of flow through the 800 as the 300, it gives you room for a potential clog and possibly not flooding. Better to have more overflow capacity than maximizing the flow within your overflow.

Hope that didn't confuse you.

Running carbon and phosban is not a necessity. However, IMO it is a good idea to run both. JMO

and also if I use a 300gph overflow, and a 500 pump, the pump at 5 ft is less than 300 so it should be fine right?

You should be fine.
