What did you use to chlorinate with prior to the switch to bleach? If you were using trichlor, then it's a pretty good bet that your CYA is way high. There are several kits out there that test for CYA (aka stabilizer). You can pick up a Taylor kit at most pool stores. Or, if your local WalMart still has pool stuff out, they have a 5-way drop-based kit for around $15 that will test for CYA.

And yes, the extra leaves in the pool can add to the algae problem....indirectly. The available chlorine is being used up "sanitizing" the leaves, and not the live algae that it needs to fight.

Watermom's given you good advice. Try to get the Chlorine level up to 12 and hold it there, and in the meantime get a kit and test the CYa yourself. With a test result, we should be able to help you get it cleared up.
