i run a Reeffanatic dual float switch...which 2 are highly unlikely to fail at same time, however not impossible
my ato game is not up to par, jesse any you would suggest?[/QUOTE]
I went with what I feel is the best in the game, which is the tunze osmolator. No actual moving components that can get stuck. That alone has worked but I also bought the apex and once I get that hooked up...(cough cough omar hooks it up for me cause he's such a pal and I am a putz with electronics) I will have it set up to where if my salinity drops by 0.01+ I will be notified by text, email and automatically have my ato turn off.
