New User Getting Butt Kicked By Algae

Do you folks NOT recommend using Muriatic Acid to raise CYA?

No, no we don't. It doesn't. CYA (aka conditioner and stabilizer) does as does trichlor and dichlor.

I checked an online pool calculator the recommends 3 gallons of muriatic OR a little over 7 lbs of dry acid.

I would burn that link and never ever ever use it again. Your pH is already low.

I also read that muriatic acid won't bring my pH down like dry acid (?)

Nope! muriatic acid (HCl) lowers pH and nothing else.

It's probably not a good idea to mix our advice with whatever you read wherever else.
