Thanks for reply

I am using HTH shock for the time being 56% CalHypo but also ordered 24 lbs Doheny's pool shock 66 % CalHypo. Once I receive it I'll use that product and will report the results.

I'm also having bubbles in the return do you know of a good product to reseal the connections without taking them apart? I wrapped shopping bag and it seemed to slow it

I bought Rectorseal's Tplus2 from HD would that work or what product should be used ? Would appreciate suggestions

Thanks
Matt
