Please note that you have 2 unrelated problems:

1. The flow indicator on your SWCG is not working (assume that there actually IS flow), so the SWCG is off. You may need this:
Hayward GLX-FLO-R Flow Switch Assembly without Tee Replacement Kit for Hayward SWCG

2. Your pool is about to turn green . . . or has already done so.

There is ABSOLUTELY no reason why you cannot chlorinate your pool manually, until you can get your SWCG repaired. SWCG's should ONLY be used for routine, normal chlorination. You should chlorinate manually during start up, winterization, and anytime there is a a problem.
