As most of you know (ad nauseum) I've been fighting the dreaded Hair Algae
all summer. I've been adding nutrients (Iron, Potassium, Magnesium,
Nitrates), Aquazyme and Water Lettuce but the Algae kept marching on at
the expense of the other plants.

** I had the same problem with one of my 150 gallon pools of fry. I finally
removed the fish and carried all the infested plants to the compost pile,
hosed out the pool, relined it with a new dropcloth and started again. So
far so good.

I even tried the miracle grow bath for the WH a
couple of weeks ago (helped a little) but the plants were losing to the
Algae. Except for the Lilies which I've been supplementing with plant tabs
and they've claimed half the pond from their two small pots. Well a couple
of weeks ago I started dumping my excess Hornwort from the tropical
aquarium into the pond, probably 10 gallons over a two week period. This
stuff doubles every week in the aquarium (CO2 added) and takes the light
away from other plants. This has forced the WH and Water Lettuce to the
outside of the pond, starving the Algae of light and out competing the
Algae for nutrients (Phosphate I suspect). So the WH has finally started
to perk up, adding new white roots and putting up a second story
(knuckle).

** Fantastic! My hair algae all but killed my pond week (elodia) and
hornwart in that one pool.

The Water Lettuce is still yellow looking, but I added some more Nitrates
today, which really perked it up last week. I suspect a number of factors
have finally helped to curb the Algae, but it's nice to believe in the
miracle of HW.

** They're heavy feeders and will shade out what's under them! :-))
