I read your ReefKeeping article about the dangers of autotop off. While my system isn't foolproof, it is immune to most of what you mention in the article, and it cheap and easy to set up.
I have a solenoid connecting to my RO. Power to the solenoid is on a $10 timer I have for lights. The RO runs into my sump through a float switch.
I do have to carefully adjust the timer so it replaces exactly what evaporates. But if I am close, it is the difference between adding 5 gallons a day and 5 gallons a year.
If the skimmer overflows (or anything else lets salt out of the tank), extra water will slowly get added but the water level will drop. Salinity will remain constant, even until my pump sucks air and dies.
The only way the system fails is if both the timer and the float switch fail at the same time in the on position. There are a lot more probable ways I could lose my reef.
Yes, if someone dumps loads of copper or pure ammonia into the water, I will lose the reef. But wouldn't I lose it if I added the water manually?
