Wondering what’s the lowest the water can be for my aqua clear 110? I don’t see a minimum water line on it... I don’t want to ruin the motor... I keep my tank mostly full but not to the top, as I have mystery snails that lay eggs.
While the AC's are running, I can drain the water in our 75 gallon down to below half way and they will still draft water just fine up the intake tube and pump water. Our AC110 will make a huge water fall effect before I unplug, when I'm about to refill.
I'll unplug them before the water line drops enough to get close to the end of the intakes so they don't suck air.
I won't plug them back in until the water line is back up to normal. I would think they would struggle to draft water up the intake tube when plugged back in, if water line was around half way.
If around 3/4 or more full, they have no problem drafting water once plugged in if their reservoir was topped of with water first.
From my experience with different AC models, they will pull water very easily while running. Just be sure to top off the reservoir before plugging them back in. It won't draft water if its empty.
