ATO suggestions

[WarDog]

Here is a pic of the ATO in action. The minimum run time is 20 seconds so I've had to slow the pump action with a TLF 1/2" ball valve, as I mentioned.
If it fills too fast the water level will rise and alarm will sound (annoying), not to mention messing up your salinity.
I have also noticed that the sensor needs to be cleaned of salt creep once a week. I use a Q-Tip.
Overall it seems like a good system, so far.
