PH and water density/flow?

I believe Untamed had this same problem maybe PM him on his solution

pictures of your sump and general plumbing setup would be helpful.

No pics, but pretty basic sump setup. 1" Herbie flows into sump, through some baffles, and Little Giant 4 pumps back to tank. Only other thing running off the LG is a Phos reactor, at a reallly low flow. I just got a Kill-A Watt. Checking the voltage at the pump from lights on/lights out. Should not have a drop, but you never know.

Do you have a ball valve or a gate valve on your herbie? I understand some ball valves are 'inaccurate' or hard to adjust, and I've heard of valves 'adjusting' themselves under pressure... could be the valve.

Ya forgot to add, got a gate valve. Next step is a flowmeter on the sump return line, see what the pump is acctually pumping up to tank.

It's not a major problem, just gets annoying as every 1-2 days I need to adjust the gate.

OK, I have figured it out. My Mains power fluctuated between 117.3-120.6v throughout the day. I'm on a community grid system, so the more power demand during the day, the lover the voltage. Just enough to cause a little flow variation in my return pump. Now, anyone know of a good power conditioner? I am going to try my UPS, see if its constant, but I think it fluctuates with Mains as well, only switches to battery on power fail....

Need to figure out how to make a auto Buck/Boost transformer

Edit, Nope, My UPS drops from 118 to 108 upon power fail. so it does not actively condition the power

They also make a 1000VA unit that is black and has Home Theater written on it so it costs five times as much.

Way to go Sherlock, excellent deduction, I will have to remember that little tip.
