Mendy,
Sitting in your pool will also help. Chlorine has a way of killing algae, bacteria and if a salt water based pool the saline will help bring the fungus out
Years ago when I was a kid, anytime we got Poison Oak we would just go swim in the ocean and it dried it up in a day or so.
One thing to also keep in mind that you could be exasperating the issue by mixing all the various treatments. Stick with one for a few days to let it do its thing.
Cheers
