Can’t maintain Chlorine levels

I have a brand new pool. 1 year old. I have an in-line chlorinator and Ozone. My pool only needs to be around a 1-2 ppm. I use these Clorox tabs and it doesn’t work. Every week I check it and there’s no chlorine and I have algae. My CYA is 90 so I’ve decided to switch to liquid chlorine without CYA. It’s been really hot and my pool takes sun all day but why aren’t my levels staying up. I can’t figure it out and I’m very frustrated. Any advice would be much appreciated

Welcome to the forum!
How are you testing your pool water chemistry?
IF the CYA is really 90, a healthy water exchange with fresh is needed to get your pool water chemistry back in order.

I suggest you read ABC's of Pool Water Chemistry.

You need to keep your FC much higher than 1-2ppm. Don't believe the ozone hype. You need to follow the FC/CYA Chart to ensure the water stays safe and clear. Of course at this point you should replace water and follow the SLAM Process.
