new home owner -- new pool owner -- clear as MUD

To see sigs, I think you have to go back to the user control panel somewhere in the settings and enable it. I don't have time to look for it right now. See if you can find it and if not let me know and I'll look for it a little later.

CYA to 25 and then use feeder til it hits 50 is fine.

Backwash your filter. Always turn the pump off before you move the handle on the multiport. First move it to backwash. Watch the discharged water and backwash until the discharge (not the little sight glass) looks clean. Usually takes mine about 1.5 minutes or so, maybe a little less. Turn pump back off, put handle on rinse for about 15 seconds. Turn pump back off and put it back on filter. Note the clean pressure. That will be important to note because the way you tell it is time to backwash is whenever the pressure rises 5-10psi over the clean filter pressure. I have always backwashed right onto my lawn for years and it has never hurt it at all.

EDIT -- You don't have to add the CYA so slowly or it will take a long time to get it to register and during that time, you'll have trouble keeping chlorine in the pool. Go ahead and add it all to the sock. 9 oz. is only going to give you about 5ppm. It's going to take a little over 3 lbs. to add 25ppm. So, you need more than 33-oz.
Out the door for a bit to run some errands but I'll check back in on you later this afternoon.
