What to do if I have done SLAM incorrectly?

Not sure what the bubbles are. Are they coming out of the return?
Try smearing the material you are concerned with on a paper towel.

The bubbles are on the walls all around the pool, not coming out of return.
I’ll see if my son can get some actual “sand” from the bottom of the pool later if it’s not too cold and will report findings...thx!

Do not worry about the bubbles on the side of the pool. Nothing to do with algae or anything you are doing.

This sandy stuff. What happens when you smear it on a paper towel?

It’s still a bit cold for my son to go in...but here is the pic when I smear the stuff from hairnet..it kinda roll up into this...so doesn’t feel like sand?

If it does not smear into a green/yellow color, then it is not algae and is just dirt, etc.

I would suggest you just move on and let the FC come down to target range, add your salt, and fire up the SWCG.

If it persists, then it would be time to check the laterals in your sand filter for a crack.

My son went into the pool and he said it doesn’t feel like sand and just goes poof when he touches it...he couldn’t get a sample out from the bottom for me...how does one check for lateral crack?

As I do not have a sand filter that is out of my wheelhouse. I believe it is pretty obvious when you get the sand out of the filter.

Run for awhile and see if it goes away.

Ok thx!!! I’ll go down to target and see if it gets worse! Thx for your help!
