I have a 220 gallon tank, so I get a pretty large amount of evaporation. Enough so that I needed to get a dehumidifier to keep the humidity in our house down, because it was getting out of control. That said, ever since I got this dehumidifier, my protein skimmer has been out of control, overflowing like crazy. I’ve turned it down quite a lot and it is still overflowing. It had been tuned for give or take 6 months prior, so I’m not sure why this is all of a sudden happening. On one hand I can’t see why a dehumidifier would cause an issue like this, it’s about 10 feet from the sump. But on the other hand, the timing is kind of convenient and nothing else really makes sense? Would the humidity dropping make a difference? Or would the air the machine spits out maybe make a difference? Or does anyone have any other ideas of something that could suddenly do this?
