so i have been using rain water for my topping off now for 3 weeks.not for water changes though cause i cant get enough to water to make the water change.i have to say i am extremely happy with the results.i always check each batch i collect and my cyano has gone away and i noticed alot less algae film on my glass.i even see more coraline growth on my rocks.has anyone ever tried this before.
