If it's a clear green, then it may be metals in spite of their not measuring any. In that case, lowering the pH will probably improve it (your pH is much too high) and you can then use an HEDP-based metal sequestrant unless the water is completely cleared up from the lower pH alone. If the water is a cloudy green, then it may be algae. Your chlorine level is too low and I wouldn't trust the pool store results anyway, especially not for CYA. Get your own good test kit and take charge of your pool. Read the Pool School for more details.

You have to get the PH down. Clorine is ineffective with PH that high. Muratic acid is best
