Well, since I had to be at work all day yesterday while my 120 was crashing at home, I figured I'd at least get a little work in on the nano.
I added a JBJ
ATO auto topoff system. I really like this
ATO solution. It's nicely packaged and works very well. It comes with 2 float valves. I have mine set up with sensor 1 in the
sump, and sensor 2 in the
ATO reservoir. When sensor 1 is activates, it turns on a Aqualifter pump sitting on top of a 5 gallon bucket of
RO/DI, and pumps water up to the rear chamber of the nano. When the water level in the reservoir gets low, sensor 2 will activate, turning off the pump, so it doesn't run dry. it has lights on the front so i know it's on, if either of the sensors is activated, and if the system is pumping. So far, so good. it looks like I loose about 16 ounces a day through evaporation.
I also added a float to the rear chamber of the nano, and connected it to the Mag 2 return pump. It's set up to cutt off the pump is the water level gets too high. I decided to add it in the event that the drain got clogged or otherwise restricted. Since the
sump is bigger than the nano, it could create a real mess. Hopefully this will protect against this happening.
Last, i added a Pen-Plaxx battery operated air pump. this pump runs on 2 D batteries. You plug it in, and it does nothing. If it senses the power is off, it will start the battery powered pump. I decided this was a good idea after a power outage a while ago cost me the true perc living in the tank at the time.
