I have been dealing with yellow algae in my pool and a couple of days ago began to SLAM the pool. I had ph down to 7.2, CYA at 30 and FC at 12. Last night we received 3" of rain to the point that the water level is at the top of my above ground skimmer. It is still raining so I have not been able to take current readings. What affect will I see to my SLAM efforts.
