The tapwater here is off-the-scale hard, so I collect rainwater from the
downspouts & keep it in 5-gal carboys for all my plants. Must have some
dissolved organic matter in it, because often it turns murky & gets real
stanky, like marsh gas. What would be the best way to treat this problem?
H2O2? Potassium permanganate? Or, ?


I have a dozen water barrels around the house at each downspout and
every time one of them is empty I wash it out with soap. You water
has anerobic organisms thriving. Another thing you can do if you only
have one barrel is to buy a cheap fish tank pump and attach an aerator
to the end of the tube and keep the water aerated.
