Added Stabilizer to bring CYA up to shock but no luck

[bmoreXHotPro05]

Hey guys,

I've struggled mightily this year trying to balance my pool chemical levels so I had to resort this.

Current readings are as follows:
FC: 0
CC: 0
PH: 7.3
AK: 100
CH: 290
CYA: 20

I just put in 4 pounds of conditioner and cycled it through Wed to today. That bumped my CYA up to 30, so I shocked it with 5 lbs of HTH granular chlorine. I normally use liquid chlorine, and the local discount store has the Austins Pool Tech Shock, but that has not been working for me.

What are your suggestions on how to stabilize and maintain a reasonable FC level?

Welcome to TFP!!!

First, what test kit are you using?
What does the water look like?

What is the ingredient in the "shock" you are using? That is either raising your CH or your CYA, both of which is not good.
If you can not hold any FC, then you likely need to follow the ShockLevelAndMAINTAIN Process.

Welcome to the forum.

Chlorine is a consumable item and is consumed by organics in your pool and UV from the sun. Your chlorine has been consumed by a combination of those two things and needs to be replenished.

read "The ABC's of Pool Water Chemistry" up in Pool School.......it's a great place to start learning how to manage your own pool water. Asl lot's of questions and we'll help as much as possible.

What does your water look like?

I'm using the Taylor 2006 kit. The past 4 years I've been able to maintain my pool but for some reason this year is a different story. The water is not crystal clear but it is fairly clear, with a few spots of dead algae that I just cleaned up.

Add 10ppm of FC to the pool with bleach and test the FC and CC in 30 minutes and report back.

Took the FC reading after 30 min & at the hour mark and registered 10PPM.

Seems that most of your chlorine loss is likely due to the sun as a result of having a low CYA. You should probably raise the CYA a little and then slam the pool.
