Color change?

[momof2grlz]

We had no color change either last week when our SWG was finally started. At 100% output for 24-hours, our SWG got the chlorine level well above 3.0 in our 10,000 gallon FG pool, but not nearly high enough to shock to clear an algae bloom.

Pool has cleared up. I used the swcg to shock to 24 hours and then had all chemicals checked - low on cya and calcium, high on pH.

Corrected levels and pool is blue and gettting clearer daily.
