Cal hypo powder, even I don't need CH but my reading was like nothing.

This year some how after I SLAM the pool this thing on top of water show, close look is tiny bubbles stick together. Even I'm adding water it show out from nowhere. Any one know what it is? While I'm lower my water so # are unknown now. As before after the slam Vinyl pool pH 7.2 +/- Alk 100...

I guess best bet is just replace the whole key union, to remove the handle pin need compressed tool.

Hayward vari flo xl sp0714g11m onsp0714t sand filter

Bummer, I open top of the multi valve, it seems pretty good on the gasket and internal no sign of crack or anything. Could it be the plastic ring right under the handle? It broke as well?

I just noticed this year that when on filteration mode,I have leak on the waste output so I add a valve to close it. Then while I was doing waste out I saw I have very slow flow on my return??? Do I have bad internal multiport? Affect my filteration?

Dose anyone know how much FC dose 3" tab supply per 5k water? Just approximately is ok. Thanks

Hayward t cell? Dose it have any label on the device?

Thanks. BTW what is the highest ppm of salt to keep the equipment safe?

Wow jump in at high FC? Isn't that is not good?

Can you oxidizing shock the pool while SLAM the pool while have enough FC? will this helping speed it up for cloudy pool? thanks
