Low water pressure after adding calcite to acid neutralizer

[Rona1d]

I am watching some videos and I did not slowly refill the tank with water- I just closed it up and then backwashed. I have a feeling something is clogged.

any tips on how to check?

im trying to upload pictures but it says the files are too big, right now it is in bypass and the pressure is normal. i dont see how it could have clogged the dip tube since i just poured it in through the hole

How much did you add? What size tank? What type of calcite?
