Reducing flow rate

[PufferCorps]

Finally got the Walmart Marineland sump built, started it up today and I need to slow the water pump down. the pump is sucking all the water outa the sump and trying to overflow the tank.
Is there a way to control it?

Thanks!

Can the overflow not handle it? Making the pump pump higher before going into the tank is a potential way to slow the flow, albeit an unconventional one

Tee off the return line to the sump, add a valve, and return the water to the sump,

I agree with Joe, if you tee it off, you can then control flow with to the tank with a ball valve, having the excess go directly back to the sump.
This extra flow to the sump will add agigitaion and oxygenate the sump creating a better environment for benificial bacteria.

There is also the option of adding a venturi tube to the outflow line to the tank, ventures automatically drop pump pressure by about 20%, and at the same time add aeration to the tank.

DC pump is the only way to go if you are willing to spend more money to save you the headache.

What size tank, what size overflow, what size/model pump and what's the head height?

Thanks Monster Pals!!!

This is my first sump. i had been getting my directions on building it over the phone from my shelter operations tech, right up until he ended up in the hospital in a coma. I'm winging it now.
Check out the pics. I have no clue what the hell kinda pump it is, and whats a head height?

Hey, don't judge me. I learned all there is about pvc fittings in the last several weeks. By the time this things running I'll be able to turn a horse tough into a hot tub.

Can I use a dimmer switch to slow it down?
