High all for the first time in a few years I am having a lot of issues with my pool and need help.

I have a 24ft x 52” round above ground pool. With a Hayward EC50 DE filter and Hayward PowerFlo MATRIX Pool Pump 1.5HP.

To start this year I tried to use the cellulose filter media it was great for the first month and then my filter started short cycling with cloudy water. Fast forward to yesterday the filter was short cycling with no media in it so I shut it down and used a filter cleaner this morning(made the grid look brand new. I reconnected the filter and loaded with 10 scoops of DE(what I read is 5lbs). Added a skimmer sock and tested my water:

Hardness - 81ppm
PH - 7.8
Alkalinity - 106ppm
Cy acid - 40
Free chlorine - 0.2 ppm
Total chlorine - 3.2ppm

This was after using a chlorine free shock. I noticed the liner was slipperier than normal so I adjusted hardness(I know this isn’t a big deal for vinyl liners) up to 250ppm and then shocked with chlorine powder 4 hours later. The bag said 1 bag per 10,000 gallons so I added 2 bags since I had 0 free chlorine. It’s been 2 hours now and water is still cloudy I assume due to too much chlorine. But there is also white powder at the bottom of my pool. I am not sure if this is DE or excessive shock?

Also on a side not the filter shock I put on the skimmer I replaced as it was filled with crud. The second sock is now also filling with crude.

Also the filter pressure is 18psi which is pretty normal I am usually at 16psi.

Any help or suggestions would be greatly appreciated before I go down too many rabbit wholes.

Thank you in advanced.
