Bleach is actually the best way to clear up the mess you have!! Chlorine is chlorine is chlorine once it's in the water, whether it comes from bleach, trichlor, dichlor, or whether your SWCG generated it from salt. SWCG's are designed to keep adequate chlorination in pools to keep them sanitary to swim in, but do not have the ability to superchlorinate for as long and as high a level as you need to clear up an algae bloom. If you'll post your CYA level and your pool capacity in gallons, we can help you figure out how much bleach to add--but it is definitely the way to go with your situation. Once you get the algae gone and the pool cleared up, then you can go back to using the SWCG for regular chlorination and just use bleach whenever you want to shock it. Also-your pH level will not rise considerably due to the bleach--that's going to rise as a function of the SWCG.
