Doc4PC2 Posted June 18, 2014 Report Share Posted June 18, 2014 I ran tests on rain water over a one week period. The rain water was run through a sponge filter and that was all. I also let some set and tested it each day for a week. I get all tests exactly the same as my RO water except, the TDS is 20, and my RO TDS is 4, and there is .5 ammonia in the rain water. Other than those two differences, the water is exactly the same all across the board as RO water. I feel like I could use the rain water instead of RO water in my tanks no problem. I live in the mountains, so as long as I run it and colllect it through a filter or two coming in and going out, it is just as good as RO water. What do you think?

High5's Posted June 18, 2014 Report Share Posted June 18, 2014 Rain water is great if you can collect it and it's free. I'd suggest you age it for a few days re mineralize or use it for top off Quote Link to comment Share on other sites More sharing options...
Shrimpo Posted June 18, 2014 Report Share Posted June 18, 2014 .5 ammonia could be birds poop, make sure not to collect the rain water from the gutter, find a way to get it directly from the sky. I am also thinking of using rain water and run it through activated carbon just in case. Quote Link to comment Share on other sites More sharing options...
Doc4PC2 Posted June 18, 2014 Author Report Share Posted June 18, 2014 I did age it and test it every day for a week, and I did not collect from the rain gutter, but I will filter it going in, and coming out. I'll have to try the activted carbon. The ammonia was very insignificent at .5, and I can use a good prduct to get rid of even the .5. and use Bee Shrimp Mineral to get the TDS to 135.
