acid water and algae

This is interesting.  As a matter of fact, I was going to ask about
something similar, because while checking the weather channel this morning
(more rain, rain, rain, but I digress...), a gardening expert named Art
Drysdale was talking about his outdoor pond.  He uses some products from (I
think it was) Sera in order to make his pond water more acid.  His only
reason:  to prevent algae growth!  I imagine peat would have a similar
effect.  Does more acid water really discourage algae?

support the hypothesis that decaying peat not only provides your aquarium
w/ Co2 but also releases algae retarding chemicals overtime.  I
consistently noted how I have not had a green water problem in my
predominantly peat / vermiculite substrates snce I've been setting them up.
