So I have a problem with my pool. It's been almost a week and my pool is extremely cloudy. My father usually takes care of the pool but since I was having a party coming up, I decided to take care of the pool myself.

The pool was opened a month ago and no chemicals were added except shock since the pool was opened. So I knew something needed to be added so I took a water sample to my local pool store and have them help me with what my pool needed, which was basically everything. The pool store told me I needed almost everything. They told me what to add and how much to add. They said to add a new chemical every 45 min from each other to prevent cloudiness. My filter was running the entire time. I put the chemicals directly into the pool without diluting it.

I added
+ 50 lbs of calcium.
+ 5 lbs of pH,
+ 8lbs of stabilizer
+18 lbs of alkalinity. B
+ 4 gallons of liquid shock l

I backwashed the pool. It was still cloudy so the next day, I backwashed the pool again like they said then added 1lb of powder shock(without diluting it) because the instructions said DO NOT ADD WATER.Its been almost a week and the pool is still cloudy. I cannot see the bottom. That is when I noticed tons of chemicals at the bottom and moving it around made it even more cloudier. I put my robot in there and it has been picking up alot of the chemicals at the bottom but I know for sure there's more. Today I tried to take the net and pick some up but now its rough and seems like it is stuck to the pool. I just got this pool liner last summer and I know it is discolored for sure which is pretty upsetting.

Sorry for the long post, but I wanted to make sure I covered the basics of what actually happened. I cannot see the bottom so I am not sure how much is still down there. BTW I have a 30k gallon pool and it is 9 feet deep. I cannot drain it because it vinyl.

What should I do?
Chlorine 0
Cya 100
Ph 78
Alk 120

Tried brushing it and the bottom feels rough and there's sand on the stairs
