Best Shock for Algae

[spatt]

Well, I doubted my little Wal-Mart was going to have the HTH kit but they did!

I have run the tests and here are the results. Also, I updated my signature line with my pool specs.

Temp - 86
TC - looks a little greater than 5 ppm but the test didn't go any higher.
PH - 7.6
CYA - 80 ppm
ALK - 120 ppm
Hardness - 700

Doesn't that all look pretty good other than the chlorine and the hardness?

Honestly, I need to get a picture of the "algae". I had a pool guy look at it and he couldn't tell what it was.

I went to my local pool store and followed his directions. I shocked it two weeks ago with bioguard 3 and immediately followed with bioguard banish. I brushed before and after for several days. After a week I cleaned my filter cartridges. I saw no results other than foam on the top of my pool the next day.

Then I was able to go to Leslie's (after reading the forum, I wish I hadn't) and was told to use their Black Algae killer. I added it per the bottles instructions on Thursday last week and brushed. I waited to wash my filter cartridges. Again I saw no difference. The pool foamed again and a green gunk stuck on the water line around the pool. I'm still struggling to get that all cleaned off.

Lastly, my husband got into the pool with a chlorine puck and scrubbed each spot but I still see no difference. And, it's not spreading quickly either. It has stopped where it is so maybe thats progress. Or maybe it's just a stinkin stain and I cant tell (insert hair pulling emoji here)

Thank you for your time - I really appreciate it!
