DIY ATO

[ReefZ1lla84]

So I made a ATO using a 5 gal bucket and a 1/4 rodi bulk head and a float valve and 1/4 ball valve. Curious to see other reefers DIY ato set up

float and top off hose holder

5 gallon reservoir with second float to shut off pump if water level drops too low

box with 12 volt power supply, timing relay in case float in tank fails, and second relay controlling outlet so I can use the float in the tank to set my water level during water change.
