Reefing newb
I have had my BioCube 14g for little over a week now and i have one concern. The water level in the pump section of the back tank drops about an inch or two ever 8 to 10 hours. See image below. I though that is could be leaking, but it wasn't. Then I thought that it evaporated, but really!? That much in 8 hours. I have been refilling it with plain RO water because salt doesn't evaporate, and it maintains the same SG at 1.024 after a few hours after the top off. So my question is; is it possible for that much water to evaporate in that little of time?
