I toyed with the idea of doing timed method this when I was adding kalk to my ATO for some consistency but I really dont have that issue anymore. My ATO tank is only 10 gal so if the ATO fails worse case is the ATO pump burns or I add a max of 10 gal water to my system which would be like .5% total system volume - likely wouldnt throw off any parameters persay.
You could switch to an Aqualifter pump, which won't fail when it pumps air, it will just be an air pump.
Decimals are tricky :lol2:
A 5% change is not huge, and would be like going from 1.026 to 1.025, not a huge deal, you're right, but if it's easy to fix, why not?
And suppose you have a power failure right after the ATO fails. Will the water returning to the tank cause the sump to overflow? :sad:
