FC loss, Algae?

[Etek14]

Will the FC ever get ahead of the Algae if your maintaining the recommended level of chlorine ppm? I am not talking green pool. Pool is clear but .5 to 1 loss overnight. NO CC's. Is this amount of unseen Algae an issue for swimmers?

Is this something you saw once, or is it happening every night? The test is accurate to +/- 1 drop so a 1ppm difference is within the range of uncertainty of the test.

A loss of 1pm overnight is acceptable and nothing to worry about.

Paulr, FPM. Thanks, it looks like i'm within the margin of error. That slipped my mind....
