The water level in the last section of my sump has dropped about 1/2 inch in 24 hours. Is this due to evaporation? If not, any idea why? Heater & ATO are not running & 1 power head is currently running.

I am not sure either. I am trying to get the return flow to match the drain flow before setting up ATO.

1%-2% of total volume per day

Yes, it is the return section. Heater is not running, water is 69 degrees & it has been cool here. I was thinking evaporation but wanted some input from others.
Thank you

I lose about 1 gal a day for my 75gal.
You said you are still trying to match the return flow with the drain flow. What does that mean? The drain should handle anything the return puts back into the tank. Unless you might be talking about adjusting a Herbie or Bean system to be stable and quiet?

I am using a valve to turn the return pump flow down because the drain flow cannot keep up. I have a valve on return & drain. With both open 100%, the return pump drains the sump. Drain cannot keep up.
Have I done something wrong?

Nope, that's normal. Sometimes people put a valve before the pump, which is bad for it. Some say a valve on the drain can be a trouble spot, because it's a place for snails to get caught or whatever and clog your drain. But a lot of people do it to quiet their systems. Either way it's a good idea to have a fail safe on your system so that if the water isn't draining back into the sump you won't pump the sump dry and flood.
I suppose that a super huge pump with the valve closed almost all the way might cause trouble, but just a small adjustment is nbd

If the tank cannot drain fast enough then would, could T off the pump to a reactor or refugium or just back over to the skimmer section to slow pump downa bit
But id agree with not valve on drain line and adjust the pump

The final return section of the sump will be where all system evaporation manifests. As long as there is no evidence of a leak then, yes, 1/2" in 24 hours seems almost certainly like it is evaporation. Think about it this way: if your return section volume is 5 gallons, and the daily system evaporation is 1 gallon, then you'll lose 1/5 of the volume in that section every day.
BTW, unless you are running a dual (or triple) siphon-based drain system, NEVER constrict a single drain with a valve. You are simply ensuring a flood, and soon.

Totally true. I forgot people use single drains, my bad.

Unlike others, I will say that if your drain cannot handle your pump(besides gurgling noise), then yes, your doing something wrong.. Well not you, but your piping.. Your dreams should easily be able to handle the return pump flow without valving. Being quiet is another story..
But, even if it is cool, depending on flow, surface disturbance, etc, yes, you can evaporate a ton of water. Half an inch in 24,depending on the size of the tank and fill system volume is nothing.. Especially, depending on the size of the sump. A half inch of a sump that's 12" wide is a large difference than a half an inch of a sump that is 18" wide.. With that said, my 75 gallon sump, which holds 30 gallons of water (connected to my 180 gallon dt), goes through 20 gallons of water from 7 to 10 days.
I can increase or decrease that level of evaporation(for kalk of i want) by varying my sump fan speed.
So things are very relative, subjective and not set in stone..

Have 2 drains & both are at 100% open.
Now if I can just get everything set so that the overflow will stay at a constant level. Any suggestions or thread links, anyone? Increasing return flow drains the sump.
