Algae Bomb?

[PoolDoc]

It's available as PoolRX (includes some copper and a little silver, I think). We don't recommend metal based gizmos, but you are welcome to try.

However, simply running proper chlorine levels, for the stabilizer level in your pool, will solve your algae problems. See the "Best Guess" page link in my signature.

If you want it easier, you can add 10 boxes of 20 Mule Team borax + ~2 gallons of muriatic acid per 10,000 gallons of pool water. If you do this add no more than 2 boxes at a time SLOWLY through the skimmer with the pump running. Wait at least 1 hour. Add no more than 1/2 gallon of muriatic acid DIRECTLY TO THE POOL (wear glasses, gloves, watch the fumes, and pour CLOSE to the water), also with the pump on.

To reach 50 ppm borates for it's algaestatic proprieties you need about a gallon of acid for every 3 (76 oz) box of borax to get in the ballpark. Dosing rate is 60 oz by weight and 30 oz of acid for every 1000 gallons of water. For 10K gallons that translates into about 8 boxes and 2 gallons + 3 pints of acid.
