Did your PB add liquid CYA or powder? If it was powder that might be what you are seeing. See what you can do to mix it up.
Lets talk chemicals:
Chlorine- You are going to want to keep some liquid chlorine on hand for fast push ups of FC like just before you have a large amount of people over and right after they leave as well. Chlorine needs to be in a shady place that is cool. Your laundry room will be a good place IF you can keep kids away.
Muriatic acid.........this stuff is not fun but very needed for pH control. When you go to use it make sure you have safety glasses on and be ready to dip your hands into the water if you get any on you. It can be stored outside in the heat and sun if needed. It must be a very well ventilated area without any metal as the fumes can cause rust. If you have small kids around you will want lock it up. Many people get a small, plastic storage container that can be locked.
Here is a shopping list to get you all set up for taking care of your pool:
-2 2cup PLASTIC measuring cups with oz printed on the side-one is for the muriatic acid ONLY. The other is for all other chemicals.
-pool brush if you do not already have one
-tooth brush ? for around the small stuff like the skimmer and return every once in a while
-nets-one flat one from the top water stuff and one deep one for stuff on the bottom
-pole for the brush and nets. I have two as I have not been able to find one that does not mess up. One I keep short for when I am brushing the pool while in it and one long one for when I am working on the pool from the deck.
-white plate-I have a plastic one. I use this to help me see the pH test. I hold it up behind the tube. It helps me see colors better.
