How do you keep you salinity at a certain level?

Can the apex work with an infrared sensor like the Tunze, or is your only option a float valve?

only float switch, yes it can be a problem if float switch failed but it can support multiple so i have multiple float switch to monitor my tank.

Also it is much cheaper to replace the pump if it failed rather the tunze one. However, cost you more for initial set up.

The Elos digital osmocontroller is well worth considering. No float switch to get stuck, very easy to set up, and so far completely maintenance free.

Tunze pump is only $32

The only dislike I have about the newer tunze is that the magnets have a tendency to move easily on their own I think cause over time by ANY minor touch or vibration, I've been trying to get mine back to exactly where it was for a week due to bumping it. I can get it there but then the polarity on the oposing magnets seem to shift a little bit every day. But in terms of stable salinity ATO is a must IMO.
