Re: Water evaporation I have a 125 with a 40 gal sump and I replace about 5 -7gal every 2 days in the summer and in the winter but in the spring and fall it seems to drop off to every 3 days. Oh and BTW as long as you add the water slowly like from the RODI tube with the amount of volume you have it may drop your salinity a point but not much more than that. I wouldn't worry too much about it. Just one of those things that I do all the time add water. |
