Hi
In my system (40 gallon display and 10-15 gallons in sump), I'm having major evaporation issues. My skimmer is skimming really wet which is contributing to the problem. Anyway I'm having trouble keeping the sump at a contant level in spite of 1-2 times a day top-offs by me. The salinity keeps getting too high. Then I rush to the store to buy distilled water and throw in a gallon or so. I know I need to set up an automated top-off system but I don't have that going yet.
Question...if I am adding a gallon a day of distilled water (or RO water if available), what additives if any do I need to add to this top-off water? I'm a little leary of "dosing" because I got my system way out of balance in calcium/alkalinity the last time I tried supplementing calcium. Then it was emergency water-change time.
Thanks for your help...
