All year, my pH has been perfect. After no pump for 12 days, I got a bunch of algea. I am SLAMing now, but I noticed that my pH is around 8.0, maybe even higher (the color seemed a bit darker than the 8.0 mark). So should I wait until SLAM is done to worry about pH, or should I add some acid now?
Also, I have never had to add any acid. What is the difference between muratic and dry, and where do I get either?
