I'd probably just use 28K for dosing purposes. It doesn't have to be exact.

Your alk is ok. Your pH is a little high. You can use a little muriatic acid to lower it. Small additions. Probably a pint or so at a time added slowly in front of a return jet. Glasses, gloves, be upwind of fumes, pour close to water surface to avoid splashing. After a few hours of circulating, test pH and redose until you get the pH where you want it.

I think your CYA is probably ok if it was kept in a closed container in a garage. I'd go ahead and use it before buying more. Add some slowly to the skimmer while the pump is running and then let your pump run 24/7 for the next 4 or 5 days. After a week, retest and then see where you are. I'd probably start with about 7lbs. That should take you to about 35ppm. You can adjust it up a little later if you need to. Better to have to add more instead of overshooting target since CYA can only be removed by doing a partial drain and refill. Most people like 40-50 for CYA so if you target 35, that gives you a little wiggle room. Don't backwash for a week either or otherwise, you'll just be throwing out any undissolved CYA.

I don't know what the super blue stuff is but don't put it in the pool. DEFINITELY do NOT put the algae treatment in the pool. Contrary to popular belief, it is copper that turns blonde hair green, not chlorine.

To save your reagents, use the 10ml water sample instead of the 25ml. 0.5 is good enough accuracy for pool testing results and it will make your reagents last longer.

Hope this helps!

EDIT -- Forgot to talk about chlorine. Until that CYA dissolves, you'll have to add bleach a couple or three times per day. Aim to get to about 5 or 6 each time you add it after testing. After the CYA registers, you should be able to go to testing and dosing in the evenings only.

Another EDIT -- Just remembered that you have a SWCG. Check your manual for CYA level requirements. I think most manufacturers want the CYA around 70 or 80.
