Living in Houston offers the clue that solves the problem, I also live in
Houston and had been amazed at how fast tanks outside turned green with
algae your comment above helps explain the cause.
I suggest that you switch to rain water. A trash can for about six bucks
works effectively as a rain catcher, but then again in Houston you could
just wait for one of our weekly floods and bail it out of the street.
I managed to collect 300 gallons of fresh rain water from last nights
thunderstorm which only lasted an hour.
Having a somewhat obsessive nature, I just finished erecting one of those
above ground swimming pools from Wal-Mart for a hundred and thirty bucks as
a rain water storage tank for 2,500 gallons.
Got to go, I am squeezing three more tanks into my bedroom today, doing
this by moving two into the living room.
Best Wishes David.
