Profilux vs Apex

[MitchM]

I use an osmolator on a 150g setup that I have. Sometimes the sensor will become blocked or clouded over with salt creep or other stuff. After I clean it up, the pump will only run for 10 minutes then stop, which means that I have to sit there and plug then unplug the unit until the sump level is back up to regular maintained levels. Ideally it should keep up by small increments, but it doesn't always work out that way.
I think that on a smaller sump volume you could probably catch the problem sooner.
