If you are using bleach, you do need to add CYA seperately, especially if you have a SWCG that you will use later. The dichlor adds the CYA for you...the bleach will not. You need to check the manual for your SWCG unit and see what CYA level they specify--different units often specify different CYA levels, and the CYA level recommended by the manufacturer is designed to help your unit run at its most efficient and make the cell last as long as possible.
Keep your SWCG off until you get the water balanced the way you want, and get the CYA levels up where they need to be. Once the water is balanced, THEN turn on the SWCG and use it for maintaining the pool. Those units are not capable of producing large amounts of chlorine quickly, even in "boost" modes, so you're just burning up cell life if you use that while trying to get the pool balanced to begin with, or while trying to clear up an algae bloom.
