I am new here and glad I found reef sanctuary. I have a 20 gallon tank with standard lighting (the real lighting will be spent on the 75g tank I have) The reef project is in the works. I have a few fish and inverts with great success, as I am not new to the hobby. My question is, Can I collect rain water in a 29gal. tank (NOT THE ROOF BUT RAIN), after about an hour of raining, and then filter it with activated carbon ?? Is this worth experimenting and what would be the main contaminates I should look for ?? I wanted to use it for top-off water and making fresh saltwater with reef crystals. I live in upstate New York (no where near the city) with crystal clear skies. I currently use distilled for top-off water and no deaths for a year and a half now.
