Dirt, Dead Algea, or Sand?

[Lastrites]

Hello Everyone,

This is my 2nd season using the (TAYLOR 2006) testing kit and the (BBB) method. I have had nothing but success ever since thanks to everyone here. The reason why I am here today is within the last few weeks we have had countless rain storms in our area and I discovered what appears to be dirt in the bottom of my pool. Hopefully, someone can identify what it is exactly with the pictures provided?

I have been on a weekly schedule with brushing and vacuuuuming since owning my pool until last week when I discovered the dirt. Since then, I have been brushing and vacuuuuming the pool daily with even using a sock wrapped around the skimmer basket to catch the fine particles the filter misses. After every session, I drain and carefully clean my cartridge filter before reinstalling and starting over the following day when the nightmare reappears. I am loosing my mind and a lot of water here!!!

FC=5
PH=7.6
TA=80
CH=200
CYA=30

These are my current water readings and my numbers usually stay around the same every evening when tested. Any suggestions are appreciated

Spotless after vacuuming!

Can you get hold of some of it? Algae feels slimy and dirt/sand feel gritty.

What is the CC test result?

I suggest you go ahead and raise the pool to shock level tonight and do the OCLT to determine if it is organic.

If it is indeed organic, you will have a head start on the shock process. Otherwise, no harm done.

Butterfly,

Tonight's readings,

FC=6
CC=0
PH=7.6
TA=80
CH=200
CYA=30

I decided not bring the pool up to shock level tonight until I preform the OCLT. I don't want to waste any bleach if I don't have to. I will update you first thing tomorrow morning with the new test readings and I guess we will go from there. I will also dive in and try to swipe a sample in my hand to feel the texture.

Thanks!

Early morning reading,

CC=0
PH=7.6

Once the sun comes up and I can see the bottom of the pool I will jump in to give you a description of the texture.
