Since the beginning of my tank I used a brs 50 ml dosing pump on a timer as my ato. It works fine but this summer with a fan on my tank I'm losing a ton of water. I found a hard let used jbj ato and hooked it up to my 50 ml dosing pump. It's still not keeping up right. As of right now the sensor is completely out of the water but my reserve is full. If I go into the stand and push the float down it will go on but won't fill it back up. Do they only run for a certain amount of time as a back up and the dosing pump is to slow. I do hear it go off hear and there but it makes it past the sensors

The sensor light for the 1st float was lit red and still wasn't pumping water. I just went and filled it by hand and the senor went on from from the water moving around. Now that bits filled the sensor light is off. If I go move the float down with my fingers it will pump

I found my answer. They have a internal timer that I can change it goes for 3 min 45 second I can change it up to 14 minutes.
