I am not sure how I got algae, I have always kept my chlorine higher that I needed to, but I have algae. My pool is crystal clear, I was sure I didn't have it. I did the overnight test and it confirmed it, I had my chlorine up last night until 18, did the test this morning and my chlorine was 12.
Here are the rest of my results this morning:
CH Didn't do it
So I know I have to do a slam, so I am going to start it tonight when I get home. My first SLAM ever, so I am nervous... My question is do I worry about the CYA test being low, do I put that in now too, or wait until the slam is over? Also, can I swim, if the water is at slam level?
