Thank you!

I have a 21' /5' ABG.

I finally have had some success in getting the chlorine WAY up (I use a Taylor Kit). It's at a little over 15ppm since yesterday afternoon. I added some soda ash .. but the Ph is stubbornly hovering around 7.2. Oddly... my alkalinity actually increased even though we added nothing for that? It's around 70ppm now.

In the interim, the pool HAS gotten more green and my ridiculous husband poured in "IMPERIAL BLACK OUT" because he SWEARS that the chlorine levels alone won't kill our algae. I am frustrated and wondering if I should just wait it out or continue my plan of maintaining shock levels (despite the algaecide) and just vacuuming as needed..
