SLAM and the use of chlorine pucks

I’ve done it again and didn’t keep up with my maintenance of the pool and it has turned green!

I have implimented the SLAM method previously to great success so I am more than happy to approach in the same way.

I have been using liquid bleach but have run out.... I guess it is OK to use pucks during the SLAM process (I understand that it can have an affect on CYA after a sustained period of time)

PH - was sky high but I reduced down to 7.4
CYA - 30 so shock level of 12

I’m seeing changes in the pool water and it’s heading the the correct direction.

The pictures have been taken during the first 24 hours of SLAM.
