Bottle ATO on my office IM Nuvo 10g started going off non-stop, which caught my attention, and I couldn't figure why. Didn't look like a clog in the AIO chambers. Pump was still pushing out water at normal level. Only thing I saw was an Astraea snail making its way across the intake grates, but of course not covering the entire surface area of the intake. Removed the Astraea and the rear chamber levels returned to normal and the ATO stopped releasing water.
Amazing that a single Astraea snail can alter the levels in the back AIO return chamber so dramatically. How does one protect against something like this?
