has anyone restricted/controlled the flow on Quiet One 3000?

[tsinkoy]

I have a Quiet One 3000 that I'm using as a return pump on my 75G. I am using 3/4" vinyl tubing as a return line with a ball valve for controlling flow.

How low can you control the flow on a Quiet One 3000? I'm test-running my system, and it seems like the water level in the compartment where the return pump is dips to a marginally low level.

I know that it is an overflow issue too. I have an HOB overflow (Hurricane Quietflo) that is rated for up to 600gph.

Yep I Do I Have One As My Return And Have It Turned Down To 3\4 With No Problems

put the value half way.

Sorry Missed The Control I Use A Ball Valve On Mine

I do have a ball valve on mine. I just wanted to see how low I can restrict the flow. Reefnob, 3/4 closed and it's ok?

You Have To Adjust And Restict It Depending On What Your Drain Amount Is Turn It Down And Turn It Up Till You Have A Level Amount At The Drain 3\4 Is What Works For Me On Dialing It Down

Strange, I have a Amiracle overflow box (also rated for 600gph) and I ran my Quiet One 3000 wide open (no ball valve) but I tee the output into two returns at each corner of my tank for additional flow. I use two of these and my water level in my sump is consistent (matched flow).

if your overflow box can handle it, why not run it full open and add a bit more water to the tank?

I'm afraid my overflow won't be able to handle it. :-(

long term restriction can lead to damages to the pump, and increase pressure to the valves and connections.

I agree with muntai, I would never restrict the flow from a return pump. I have a Q1 3000 as my return on my 40 gal & what I did was Tee off the return up to the tank with a ball valve & some vinyl tubing going back to the sump. This way, I can adjust flow without dampening the output of the pump.

That is a good idea! I will try it.
