Hi, I am new to pools and everything about them. We had a beautiful fiberglass 40x 16 diving pool put in this summer with a SWG Intellichlor.

Overall the pool company disappeared literally after the job was done 8 weeks to complete, they were in no rush. I digress.

Anyway, I have been trying to manage it myself for the last 6 weeks.

Lately, the last 5 weeks the water bubbles when you jump into it and the fizzes last longer and longer. There is no bubbles in the pool when you roll back the autocover.

The fizzes fade in about 30-60 seconds, but it really happens quit a bit. I have checked the pump for leaks etc. No air visibly being in the returns. It is like jumping into club soda, it actually fizzes and you can see it.

I tried clarifier, proper amount for pool size and volume

I have had high TA initally, the pool company never balanced it or anything, they actually kind of dissappeared

I have added dry acid to try and lower the TA on and off all summer.

Todays readings

PH 7.0
TA 120
Cy 0
CL 3

Help. I do have never put algaecide in it.

Thank you. Does it have to do with the carbonates and the TA etc?
