cloudy blue water

Thanks will do

So finally my pool is Crystal clear. I can see the bottom perfectly so thanks for your help with that. The water is nice and blue. However, there is a bunch of sand at the bottom. I put my robot in and it picks up nothing. I tried vacuuming it but its not picking up. When you touch it with something it just moves around in the water. I tried brushing it but it made the pool cloudy again for a few days then when it cleared, it was still there. What to do?

Good job on clearing it up!

The behavior of the sediment in your pool doesn't sound like sand. Are you sure that's what it is? Check your free chlorine level in the evening, and then again early morning. Is it dropping or is it stable? Go ahead and check CC, too.

I would check it tonight. What else could it be?

There are lots of things it could be. I'm thinking it may be dead algae. One thing I learned here is to keep it at shock level until all 3 of these conditions are met:
- the water is crystal clear (you have a checkmark on this one)
- the free chlorine (FC) does not drop by more than 1 ppm overnight. This must be tested around dusk and then dawn because UV from the sun will cause FC loss.
- the combined chlorine (CC) is less than 0.5

And then, shock one more day just to be sure :)

If you already meet these criteria, then the cloudiness is caused by something that's not organic and isn't oxidizing.

I googled dead algae and show come pics. It looks like my pool. It could well be that. Thanks I would of never thought of that. I checked the chlorine and its zero. I don't understand why when I I keep putting chlorine tablets.

I keep hearing put bleach. Are they talking about actual bleach like Clorox? I know this might sound like a stupid question but I'm curious on what they mean by bleach.

Btw what else can I do to get rid of it? Shocking? Or vacuuming?

Yes, when folks say put bleach, they're talking about bleach like Clorox. It's cheap, but the bottles are bulky, and you have to poor it slowly at one of the return jets so it gets mixed quickly and doesn't splash on you or your clothes.

the reason the chlorine is going down to zero is because it's getting used up--probably getting rid of the dead algae. Just keep it at shock level until it meets those 3 criteria above. Test every evening and morning, and eventually, it will start holding its level over night. The crystal clear water is a really good sign; you're definitely progressing.

Thank you. Ill try bleach and keep putting chlorine and shock.
