Well... by GEORGE MEZORI

Comments: A lot of us use Kalk/Limewater in our ATO. You can use Mode B with dual-switches and put them real close together so you don't overdose. You don't want to put too much RO/DI water in all at once either. Problem is , unlike Reef Fanatics ATO, sensor 1 and 2 act like a min. and max. where one turns it on and the other off. There is no redundacy or fail-safe. In RF's ATO if water is at the max. it won't let the pump come on. If it's not and the min. is activated it will turn off when min. sensor is raised, BUT if it fails then sensor 2 max. will act as a shut-off too. JBJ seems to be more worried about protecting your pump than your livestock with their pump protection features. I could care less about a $10 pump. The one fail-safe the JBJ has is a 3:45 minute auto shut-off, but depending on the pump that could be a lot of KALK or RO/DI water. Some people are saying even the 14 min. option won't fill their sump up.. all you gotta do is put your 2 sensors closer together. You shouldn't be dumping a bunch of water in all at once anyway.
Yes, I would recommend this product to my friends.
