thakki November 25, 2014 Share November 25, 2014 Recently bought a Tunze ATO unit from a fellow member...I have a DeepWater HOB protein skimmer instead of a sump...so I put the ATO sensor in the display tank...the ATO works fine but because of the movement of the water caused by in tank wave makers the sensor does not perform effectively...it turns on and off every other second...any suggestions for in tank ATO sensor users to get around this...looks like to me there is no other option.

mogurnda November 25, 2014 Share November 25, 2014 Can you rig up a small barrier around it to block the waves? Link to comment Share on other sites More sharing options...
MrSexyShrimp November 25, 2014 Share November 25, 2014 What about putting the wavemaker and ATO on timers so they're not running at the same time? Link to comment Share on other sites More sharing options...
tomtom2245 November 25, 2014 Share November 25, 2014 Lets see if I can explain this without pics. I had the same problem with my ATO sensor being in the display tank. To fix the problem, I got a small collection cup, drilled a hole in the lid to screw the float switch into and then a few holes around the sides and bottom to allow water flow in and out. Having the float switch isolated inside the cup prevents the waves from affecting it and the holes allow the level in the cup to fluctuate and reflect the tanks level.
