I'm a little unsure of how this would work so i'll ask before I go out and buy the dosing unit.

I've never had an ATO so I know nothing of float switches. The scenario that comes into my head is this :-

The water in my sump goes low enough to activate the float switch to top-up, lets say that is half a cm from off to on, now that means my sump needs 3 litres of water. Now the ghl dosing pumps can only run for 15mins a time so that is only 0.9 litres of water.

So my question is - Is it possible to let the pump run for 15 mins then stop for 15mins and keep doing this until the float switch is back at the top in the off position?

I use a small pump to add my fresh water, so it fills faster :)

also my optical sensor is more sensitive then 0,5 cm
