Green to…teal?

Hello all. I have a 22k galloon pool with sand filter and vinyl liner. We’ve owned our house for 2 summers now so I’m still learning the ropes. We left for a week vacation last week and despite shocking the pool (2lbs of the granular Clorox trichlor stuff) and leaving pucks in the chlorinator we came home to a DARK green swampy pool. I was at a loss to why this happened and before pulling my hair out I stumbled onto this website and read about slamming. Saturday (6 days ago) I tested our water (with Crud strips but that’s all I have currently) and it had low/no free chlorine,low/ no combined chlorine and low/no stabilizer. Ph was 7.2, hardness was fine and alkalinity was low-ok. I poured in two gallons of liquid chlorine, brushed the sides and bottom of the pool. I’ve run my pool robot daily. Next morning I tested and chlorine was higher but still low, so that night I did the same thing with the 2 gallons. Since then chlorine has remained “high” (they list 10ppm) which is the correct number according to the pool
Math app (figuring my cya is 20 since I don’t have an exact #). I’ve backwashed daily and have passed the OCLT (at least as accurately as I can figure- test strips read high at night and high next am). BUT the pool remains kind of teal/not blue and is cloudy like you can’t see the bottom.
Apart from getting more accurate test kit (which I’ve ordered), what am I doing wrong here/should I be doing differently? It seems like after 6 days there would be more improvement with SLAM levels consistently through that? Sand in our filter was changed last summer because we had issues with cloudiness. We run our filter 24/7.
