Good idea to kill algae first then vacuum. Makes perfect (common) sense to me! I seem to be lacking common sense at this junction of overload.

As others have stated before me, after reading so much sometimes the brain goes into overload and losses the ability to convert to common sense remedies. Especially when your worrying about getting everything just right. I've started taking notes to refer back too.

Two more questions and I think I got it. lol

1. Should I continue to run my filter while shocking or do I want the bleach to sit in the water to kill what ails it?
2. I am also assuming I want to continue my scheduled time for the SWG. I mean having too much chlorine is better than not enough, right?

Purchased the CYA and it's 99% pure. That's a plus, the price tag not so much. Gotta do what ya gotta do I guess. Going to put it in a sock in front of the flowing water to help dissolve. Looks like I need 1# to get my CYA approximately to the 30ppm mark. Rather start slow than have too much and have to drain. Now if the rain would just stop I could get out there and get this process started.

Thanks so much for your help BigDave, you have helped me tremendously!
