If your CYA is truly 140 (you won't really know until you test yourself with the TF-Pro you are ordering), you need to lower the CYA by drain/refill or a no drain water exchange.
The only chemicals you need are liquid chlorine and muriatic acid.
Return everything else.
While waiting for your TF-Pro to arrive, add 3-5 ppm of liquid chlorine daily.
