Syncra 5.0 pump

I understand they have a flow control know, obviously if turned all the way up it’s set for the max but if I turn it down how do I know if I’m getting enough turn over in my tank? Thanks

do you mean about the flow in the tank? Personally, in my opinion, the return pump is to return water to the display tank, a powerhead is the tool to create flow in the tank. I would not rely on the return to provide flow in the whole tank.

Gues what I meant is if I turn it down how do I know how much turn over I’m getting from the return pump.

In short, you won't. Not unless you have some sort of flow meter installed along the return line pipes.

Ah ok, added a new pump and getting a lot of gurgling and rushing water that I did t have with the old pump, ( I dont believ my old pump was working like it should have due to age) I assume it means it’s turning over water like it should but it may be too much so I was thinking to turn it down but did t want to lose the turnover rate.

I match the pump speed to my overflow's ability to keep up or vice verse. If I turn up my pump and my return pump chamber starts to run low then that tells me the return pump is running too fast so I need to adjust it down to match. So your overflows ability to feed the sump is the limiting factor or on the other end your pumps ability to keep up with the overflow ect...

Total turn over is an estimate at best without (as suggested) a flow meter of some kind.

So with the pump turned all the way up my level in my overflow does not drop at all, it just got very loud since the new pump, I don’t mean the pump is loud I mean hearing a lot more water gurgling and rushing, that’s the best way to describe it, but levels in overflow don’t change.

I'd say that's the increased water volume causing that noise. If you didn't hear that before then I'd assume the new pump is pushing a lot more water compared to the old pump. The easiest option is to reduce the pumps flow a little at a time until the noise is gone or acceptable (you have be able to live with it).

Some overflows can be "tuned" to reduce noise with pvc and/or air line tubing but you didn't list what kind of overflow you're running so no clue if that's an option.

Something like this:

The flow adjustment on the Syncra 5 reduces water going into the pump. A better way to control this would be with a gate valve in the output of the pump. More precise control and easier on the pump.
