Evaporation - what is a reasonable amount

[Coralgurl]

I turned my MP 40 down a bit last night but only because I added a couple of new clowns and a maxi mini, just letting them settle a bit. I had it turned up about 75% for the last month for both surface movement and to clean up the sand.

I really only noticed the increase in the evaporation with the addition of the fuge, cooler temps, and the furnace being on. Over the summer, I topped up every couple of days, wasn't nearly so much. The tank temp is 79-80.

Sounds like this is normal. Phew!
