Hydrogen Peroxide treatment for Black Algae

Rain water sounds all fine and dandy, but rain water also contain a
plethora of all kinds of stuff some of which may fuel algae quicker
than normal.

* I've noticed that and I live many miles from any big cities. I see algae
growing in the ran tubs outside under the Garage and outbuilding eves.

Not saying not to use it, but I persopnally would use
readily available means to buffer or adjust my PH than using rain
water if it was at all possible. Adding peat pillows will bring the
water down in ph and adding aragonite (calcium based sand ) will take
it up in PH........

* I'm aware of these things Roy but when I tried it years ago and it was
total aggravation as the PH never stayed stable. All I was doing was
fiddling with the Peat-pillows and PH-UP and the test kits. Water changes
were a nightmare as the water from the tap was always so different than
whatever the tanks were at that particular day. It wasn't worth it. And I
didn't like the looks of the tinted water. The rain water (slightly acidic)
drops both the PH and hardness, costs nothing, has no color and stays
stable.

So it is all together feasible that you are feeding
the algae with the water your collecting..Take a parameter here and
there and they all add up to potential problems.......Its common
knowledge and accepted that dust that gets blown in a pond causes
algae blooms..........and dust certainly has all kinds of stuff in it
and its on a roof or in the air and it will wind up in rain water one
way or another.

* I'm going to collect rain water for the tanks from the greenhouse roof
from now on. Almost nothing collects on the slick polycarbonate, unlike the
shingles on the other roofs. The water I've been using is from the Garage
roof. That's the stuff I see the algae in. I'll use that water for the
greenhouse plants. :-)
