The tabs are ok except that your CYA is already high enough and those tabs add CYA. Go ahead and leave the ones in the floater that are already there, but then don't put anymore in. You can save the tabs to use for a short time if you go out of town again this summer or upon opening next year if you need to add some CYA.

Keep your pool at shock level. Also, keep an eye on the pH since those tabs are acidic and will drive the pH down. Go ahead and put it on circulate.
