[CoralPlast]

Hi Guys, her's my new ATO, already have one running on a freshwater, only problem was that relais was gettin activated with turboulent fish or hand in the tank so i just added a smart plug with 2min on/off 4 times a day. sensor will be placed in AIO return chamber and will be kept in place by a glass cleaning magnet.

looks like it will work great. I think that power supply could run 100 pumps!

it is 5a and is surely overkill, but it was lying around without use :)
