My daughter unplugged it around 11 as it was still going off. I plugged it back in last night, still too high and this morning the water level hasn't changed. I usually go through 5 gls of water a day. Should I be worried, nothing appears to be abnormal.
how big is your display tank? 5 gallons a day of evaporation seems considerably high.

180 gl display, 80 gl sump.

I had started a thread a while ago about how much evaporation was normal and this was consistant with others.

The amount of evaporation is related to your homes relative humidity, the lower your humidity the more evaporation you should expect. Perhaps when you were noticing 5 gallons it was cooler outside which means relative humidity will typically be lower in your home unless you're running a humidifier fairly aggressively. With the warmer weather lately and the amount of rain we're getting relative humidity is much higher now that a few months ago.

Is it possible that the higher water level in the sump is giving the illusion of less evaporation? Due to the greater surface area. You mentioned that it is now over your baffle so is it evaporating from the entire sump now instead of a single chamber? This would create the illusion of a lot less evaporation.

Over the winter, cooler months def more evaporation, and notice less when it's warmer. I just haven't seen a huge difference to date. That said, I plugged the ato back in, pump ran for 5 secs then stopped. Salinity is 1.026. Guess the evaporation has finally slowed down....guess it was just timing of this happening.

I agree with Sphelps that it's probably related to the humidity in your house. When it's cold and dry my evaporation is pretty significant. In the summer months, dramatically lower.

Well that's fine with me, lugging 5 gl jugs from the basement sucks :biggrin:

during summer, the humidity in the air gets so high that evaporation nearly stops sometimes. My tank can evaporate 2 gals per day, but right now it's around 1/2gal daily

Yes I remember Calgary winters being deadly dry... nose bleeds and the humidifier had to be refilled daily.
