osmolator vs float switches

[Vital Idol]

I'm currently using kent float valves, but am switching to an electric one that will power a pump, its a longer story than i want to go into, but basicaly its because I dont trust kent floats with kalk water, they clog too often.
I'm trying to figure out what impact salt creep will have on those little electric float switches and on the osmolator.
What kind of maintanence does the osmolator require? Periodic cleaning? I also saw mention of micro bubbles affecting it, that is a concern for me since my skimmer does allow some micro bubbles back into the sump.
How long is the warranty on the osmolator and is there any information on failure rates or what the most common failure that occurs with it is?

It has a 2 year warranty against defects, getting the osmolator wet or covered in salt creep is not covered. In general the optic sensor should be cleaned annually. Micro bubbles are a problem and you will have to solve that. I would place the failure rate over 2 years at about 1 in a 100. Most of the time people claim something is wrong it is user error and nothing is actually wrong with the unit.
