On the bottom of my pool has a brownish dust on it, when I vacuum or get close to the vacuum it disappears. After I let the water filter it settles back. What could this be?

That is what floc is supposed to do, I think. We don't use it here so I'm not real sure...
Just move super slow when you get near it.

Its confusing I vacuumed all of it up besides the same few spots, because they disappear. I have a brush vac but also one with the wheels. I just added 2lbs of shock and 2 3' chlorine tabs.
We have a different method of pool care here. No 'shock' No 'pucks' Just a few simple things from the grocery and hardware store. Never go to a pool $tore again. OR at least, very, very rarely.

Dust bunnies on the floor that disappear when you approach them with a vacuum or brush is classic algae behavior. It's mostly dead stuff. You need to kill all of it.
It sounds like you're not maintaining adequate chlorine for your stabilizer level. Can you post test results? And how are you chlorinating?

The pucks raise the CYA level, which may or may not be a good thing. The "shock" could be adding more; there are at least three different powders that are called shock and two of them do. They also mess with the pH. In brief, you might be making a bad situation worse. Anyway.... the solution remains the same as before I can't improve on the answer you got before.
I have the Aqua Chem 6 way test strips for now. (I know better test kit) but anyway my results are
total hardness-100
total chlorine-0
free chlorine-0
pH-7.2
total alkalinity-120
stabilizer-50

total chlorine-0

If you believe those strips, your CYA is 50 so your minimum FC should never dip below 4 and you should target more like 7 every day. Your CYA will be slightly higher when those pucks are done dissolving, so 8 FC might not be a bad target for you. Pool School - Chlorine / CYA Chart
Not to step on Richard's toes here (since I would listen to him like gospel) but you need to add chlorine (preferably bleach or sodium hypochlronite).
You can use the Pool Math link on top to calculate how much you need to add. Plug in the numbers for number of gallons of water in your pool, FC = 0, ph = 7.2, etc. For your target for FC you want 8. Then mouse over to the right hand section and specify what kind of chlorine you plan to put in. The calculate will then tell you how much to add if you put your mouse over the appropriate metric.
Desperate situations like yours need to be addressed acurrately and swiftly. You can not do either at this point in time without a test kit. You are right in the middle of a bloom and unless you take your pool by the rafts and kick this bloom out of your pool, you're going to watch it take over.
You need a TF100.
Post accurate test results.

You may not want to hear it but this is what you need to clear your pool. Well be here when you decide to do it the right way.

As Richard said, read the Chlorine CYA Chart to determine what your chlorine level is for your CYA level. Never let the chlorine drop below the minimum level for your CYA level or algae will grow.
