Exactly, thanks. And after a little rain, the air is cleaned again.
I would be concerned about rainwater in your area because of the organics which would be need to removed by a basic filter before going into the tank. It would make a nice culture medium over time. If there are no nutrients, almost nothing will grow in water. Other than microfiltration and distillation, this isn't going to happen, so your water will need to be treated (if left in the tank for any significant period of time). I don't think I would want to use a deck
as a water catchment area, because of the risk of pathogenic contaminants from the foot traffic, unless you can essentially sterilize your deck. And you thought bird poop was bad.
"Add bleach to taste" doesn't cut it for me. Given the concern about chloramines, and taste, and the risk of over or under chlorinating the water in your tank, does anybody have experience or suggestions regarding ozone for water tank treatment? The theory sounds great.
Interestingly, using a watermaker
, making small batches and using it every few days, you may not need to treat the water (at least not much) if your tank is clean.
To: Little Boat. Do you have a photo
or diagram of your rain catchment that you could share? How big is the water tank?
