I agree with you about algae and bacteria. I live in the woods and have a lot of tree droppings on the roof. I'll pass the rain through a sponge filter for large contaminants but the small stuff will grow algae in the totes. I could paint the totes to prevent sunlight. Polyethylene plastic doesn't take paint very well but maybe an epoxy paint will stick. I'm not a fan of bleach because of chloramines, maybe a 10 micron poly spun cartridge filter will do. I don't think it matters if some bacteria pass through. I recall that the smallest algae particles are around 7 microns and it's probably OK if some pass through. I will check out J.R. Peters Lab, thanks for the reference.If you’ve got a way to collect and store rainwater, I’d go with that, and not be too concerned about contaminants.
It will likely be a bit acidic due to dissolved carbon dioxide and maybe air pollutants (not as big of an issue as it once was), but carbonic acid is very weak, so the moment you add anything to the water, it is immediately overwhelmed. Your biggest issues will be algae and bacteria, but an opaque tank and a splash of bleach or Physan will take care of them.
If you’d like to get a solid understanding of your water chemistry, head over to the J.R.Peters Lab website and request a sampling kit.
