Filtering rain water
Well...is there any way to do this without resorting to an RO unit? I would love to get rain water off of the roof because there would be far more water concentrated over a small area during a storm (compared to just collecting rain that directly falls into the container, as I did before), but my roof is made of shingles and I am certain that there would be certain undesirable compounds that could leach into the rainwater and kill any fish I try to keep in it unless I filter it out. I was wondering if Carbon or any other relatively cheap mechanism would work to remove such compounds (Safe T sorb perhaps? It's meant to absorb stuff like that anyway)
Side note: We have lived in this house for 7 years and there was already someone living in it before that, so I can only assume this house is at least 10 years old and probably considerably older than that. Just wanted to mention in case that information is helpful.
