I am a TFP follower and used this method the last 2 years. Opened pool(very green) this year and followed SLAM procedure. Had a few incidents (hose popped off overnight, hose leak etc. etc.) which caused delayed opening but finally got things looking good. Water was not crystal clear, but was decent for my sons birthday party. I then unfortunately went an extra day without checking Chlorine levels and before I knew it we had cloudy, slightly greenish water. Started SLAM yesterday morning. My CYA level just before SLAM was about 30. I ran out of CYA testing liquid (already ordered more), so I'm assuming it's still about same level until I get the new stuff. I am using bleach for chlorine. I actually went quite high yesterday (close to 20ppm) with chlorine hoping to get control of this. I had been keeping solar cover on pool to help maintain chlorine, but removed it this morning as we've been noticing lots of the bubble pieces showing up in the skimmer. Last night the green tint was gone but it was very cloudy still. I brushed it good this morning and now at end of day it is just (if not more) cloudy than last night. I have seen no progress at all today. Just checked chlorine and it went down to about 9ppm this afternoon (from about 16ppm just a couple hours ago...in the direct sun all day), but I just added more chlorine to bring it back up.
We have the DE filter with the fingers and use the cellulose in place of DE. Last year when we had a hard time cleaning up pool we learned how to take the filter apart and really clean the fingers out good (not just bump it, but hose it off well). We have done this at least 6 times this season hoping to get crystal clear water quickly, but it's just not working. I just replaced the cellulose again this morning hoping that would help out.
I'm trying to be patient, but was hoping for at least some results from SLAM of 2 full days.
I use the TF-100 kit. TA is about 70-80. Calcium is low. pH before shock at 7.2.
Also pump on 24/7
