alright so im now getting sick of have to top off all my water manualy, so i thought i would invest in some time to make an auto top-off system. I already have plans for what I am going to do but there is always one thing i wondered about, (this may be something i should have know during my 2 years of reef keeping) are you suppose to top off with freshwater? ive always been topping off with salt and it wasnt till a little while ago when i checked my salt level and it was pretty high! Then i thought for a bit and came up with this question, does just water evaporate and leave the salt in the tank?
