the only thing I can do is lend you my next steps I am taking in dealing with a 2 week old green pool...check your CL levels tonite, then check again tomorrow morning before the sun hits the pool...IF there is NO difference in the readings, it means the FC has stopped working against the algae...in other words, you have no algae left....you can also rub your hands across the sides of the pool wall...does it feel slimy, slippery et c?? If not, the algae is gone....

You DEFINITELY need to do the Vitamin C in the sock "thing." you Very Well may have a metals issue....In the event you do, FORGET the pool, enjoy the weekend and let the FC number drop to 1-2 PPm, THEN start your metal out treatments.....The afore-mentioned is exactly what I'm doing (except I'm buyin a case of beer as well to celebrate my findings).....!!

I NEVER had an issue like this in the past, and my cure-all was ALWAYS to keep shocking...Unfortunately, it didn't work this time.....The Vitamin C sock has shown me my issue is metal and not algae....i only wish I knew this prior to dumping 30 gallons of bleach into the water....!!!

PLEASE keep us posted as to your results and I will post to you as well to mine....together, we can get through this :> (then we can tackle the gas prices)!!!!!
