It's a 14K gallon pool (san juan mirage)
hayward perflex ec65a filter
pool was filled when it was installed last october
inground pool
You have the same filter I had in the beginning.
My guess is the pool is full of some kind of dirt or organic matter that is clogging the filter.
If you are getting the filter clean and adding the proper amount of DE, 6 lbs weighed, and the pressure ramps up too quickly then it has to be something in the water causing the pressure build up.

I'm not an expert on burning up free floating organic matter but I think there are chemicals that will do that. I added some Ultra Bright that claims “Our new stronger formula clarifer clears cloudy or dull water by removing even the smallest particles.” How it removes the smallest particles is a mystery to me.

I am not a pitch man for Ultra Bright Water Clarifier either, but I believe it did help mine.

Then I'd disassemble the filter and hose it with a vengeance, reassemble and get a food scale and weight out exactly 6 lbs of DE, mix it in a bucket with clean water and pour it into the skimmer.

Try the Ultra Bright.

It may take time to get the water “clean”.
