I like my controller (not Apex) but trust my osmolator's optical sensor more than float switches. I've had to clean a float lately that luckily I tested and found it to be unresponsive

I hit my optical with a toothbrush when I remember, but it's never let me down yet - 11 months so far
A spare pump wouldn't hurt, just in case ...
