No snails in my sump. Salt creep doesn't have a chance to form, as the water varies enough (with water changes, skimmer cleaning, other fiddling around) and washes it off. Besides, I have the higher back-up one that would kick in.
The 2nd higher float gets exercised regularly too, when I vary the water level, with other stuff I am doing in the sump. Lowering the skimmer water level (to clean it) happens at least once a week, which then raises the sump water level.
And once in a while, I test them, by just pulling the float down with my finger.
When water flows in through the float valve, I can hear it quite clearly (like a fizzing) so easy to keep an eye on it.
