ALGAECIDE AND IT'S USES

An algaecide is only needed when algae is present to a large degree. There are many reasons why algae forms in a pool. We have listed a few:

1) pH is too high

2) .6 PPM chlorine residual not being maintained continuously in pool.

3) Poor water circulation ( dead areas ) in Pool.

4) Short filter cycles

5) Improper brushing and vacuuming of the pool.

6) Remember when algae is present, chlorine consumption will be excessively high.

ALGAE AND HOW TO TREAT IT

TYPE: Green ( Chlorella )

This algae may be found clinging lightly to the walls and bottom of the pool. It also will be found floating freely in the water. This makes the water green.

CURE:

If noticed in it's early stages, you may rid your pool of this algae by three simple steps:

1) Brush the entire plaster surface of the pool, then vacuum.
2) Super Chlorinate with 10 times your normal dosage, preferably in the evening.
3) The following day, brush again and then maintain proper chlorine residual.

If this does not rid your pool of Green Algae, it would indicate the algae has a head start. After step #2, add a recommended amount of algaecide. Always follow directions on Algaecide label.
