Had to replace filter system; a Pentair 4000-series D.E with a Cartridge after having a busted D.E filter that returned a bunch of media back in the pool.
Been a slow process over the past 3 weeks to go from algae green, to super cloudy, to semi-cloudy to clear (but not crystal clear).
Was able to do a round of SLAM but couldn't maintain the SLAM for the entire duration, although it did make a big improvement from the starting point.
Been battling high CH, and never had a chance to replace the water for the past 5 years (~20k gallon). System is SWG, running a Dolphin pool robot and brushing frequently.
My plan is to increase CYA and try to level out FC for the season, but I have also been contemplating to do another push with SLAM, but not sure if that is overkill. I have (again) some spots of algae on the plaster which I assume is caused by the non-existing FC at the moment.
Would like to get feedback or recommendation on next step.
Test performed on Taylor K-2006:
FC 0
pH 7.8
CYA <10
TA 100
CH 500
