Another algae question

[jstkiddn]

Just wanted to update:

I've been super busy this week and really haven't done a lot of other things to the pool besides brush the walls and vacuum a couple of times. I did add DE to the filter. Let it run over 24 hours right after adding and since have run it at least 12 hours a day. After adding the DE, the difference overnight was AMAZING!! Still have some stuff that needs vacuuming but I think I've about got it licked. I have NOT added any chlorine or bleach. There were just a couple of green spots on the walls I brushed off today, but I think they were leftover from before. The water was so yucky for a while, it was hard to see where I was brushing. Wondering if I should shock again or just leave well enough alone?

I received my Taylor test kit this week and finally had time to use it today. Hopefully I did everything correctly, so here are the results:

Free Chlorine - 2.4 ppm ?? This one was kinda tricky. Used a 25 mL sample Turned pink with 2 dippers. 12 drops to colorless x .02 = 2.4 Right? On step 5 there was NO pink...so no combined chlorine? Right? Whatever THAT is. Since didn't turn pink, I didn't do steps 6 or 7. Is it supposed to have combine chlorine?
Ph - 7.6 or 7.8 (think I'm color blind when it comes to pinks. I have a hard time with this one)
Alk - 100 ppm
Hardness - 100 ppm
CYA - 40 ppm

The water is finally clearing up. I attribute most of this to adding the DE to the filter.

Thanks for reading and hopefully someone will tell me my next step.

BTW - One more question. If I do need to shock by adding bleach, do I add to skimmer or just pour into pool?

Sorry to be so dense, but I just want to make sure I do this correctly. Thanks!!!
