Re: Aquatic Plants Digest V4 #616

Hi Dave,

    I've collected rainwater for use in aquariums, and have never been able
to measure any nutrients in it whatsoever. Is it possible that run off from
the soil surrounding your ponds is leaching nutrients into your pond? Other
than that, all I can think of is that the addition of all that soft
rainwater is more to your plants liking than what comes out of your tap.
