Can find cause of all the dirt/sand in the pool

[nicole12]

Nicole,

This thread is rambling all over the place with guesses and no progress.

1. You have never posted any test results....probably irrelevant but it's always a good starting point.

I did post test results at the beginning of the thread:
FC 12
CC 0
CYA 100+
PH 7.5
TA 110


2. Have you actually picked this stuff up between your finger and thumb and determined it's not algae? (gritty, not slimy)

Yes it's gritty not slimy

3. Just as an aside, when you put DE in, and then backwash, you are washing the DE right back out.

I know I was just trying out a suggestion to add the DE to catch the dust I vacuum since I didn't want to vacuum to waste because my pool is so small that it would only be a matter of minutes to lose and inch.

4. Why do you put DE in your filter? (I know the theory.....I'm interested in why you think this pool needs it and how long you've been doing it)

To help to catch the small particles that the sand can't filter out. Today was the 3rd time that I've put the DE in the sand filter.

5. When you fixed the sand issue last year, what was that issue and how did it get fixed?

The main pipe that the laterals screw into was cracked so that was replaced with a new one, each lateral was checked and was in perfect condition. New sand was added.

Those answers will help get us back on track (hopefully)
