I can't get the chlorine level up

[Debs2830]

I have an 18" round pool.
All the other required numbers on the pool are good.
Ph 7.5
Cya is at 50
But my chlorine is at 0

And the water is like hazy. Not dirty. I don't see any visible algae. I run the filter 24 hours.

I shocked the pool with the HTC brand. And 12 hours later, still at 0.
I vacuumed and brushed the walls,just in case.
The next night I shocked it again. I also added clarified this time after a few hours.
Maybe I'm at 1 or 2 but still the water is not clear.

What am I doing wrong and what else can I try?

When you say you "shocked" the pool...was that a liquid or powder?? What kind of equipment are you running? Can you please fill out a <Signature line> under <Settings> ? Pool size, vinyl, type of pump, filter, how you test <which kit?> and how you normally chlorinate.

Hazy water certainly needs more Chlorine... possibly a SLAM process SLAM Process

Go put 179 ounces of liquid chlorine from Lowes or HD and pour it in while brushing the entire pool. Test in 30 min with pump running. See if that gives you some FC

I usually shock with crystals.

I poured in 150 oz. of liquid chlorine.
After 30 min ,still nothing.
But I'll give it more time.

How are you testing your pool water chemistry?

 

[Debs2830]

Clorox scan strips

 

[mknauss]

Ok. So your data is not accurate. I suspect your chlorine could be very high and bleaching out the strip.
TFPC does not provide guidance with test strip or pool store data.
Get a proper test kit. Test Kits Compared

You know what one of the many issues with test strips is? High chlorine levels can bleach them out and it will read zero. That may or may not be what's going on here (no way to tell if all you have are test strips) but imagine if you're just pushing the chlorine level even further through the roof because you're working off of bad data.

And if that's not the problem, we're going to need reliable data to help you figure it out.

I also checked the liquid testing with the 5 drops.
It's barely clear. Not turning yellow

Well that's good and bad. Good that the FC level isn't secretly though the roof. Bad that you still have a problem with your water and no way for us to help you diagnose it.

Never add granular chlorine when trying to get rid of algae- it contains half the volume of yet more CYA....which raises your goal FC level.

Liquid Chlorine only.
