Another thread I read says chlorine is not harmful to plants, but does kill some harmful bacterias in the soil.

And tap water slightly raises Ph due to added Ca, and my Ph is too low.

So maybe I should just use tap water, if chlorine is not bad for plants?

And even if chlorine is bad for plants, those fish tank drops that remove all chlorine, chlorami/des/nes and ammonia are safe at higher dosages for all aquatic life...?
