Did aluminum sulfate fix my pond?

I mention it in the video but I’m sorry for my allergies. I film videos randomly and when I get the chance. I also happen to have allergies a lot but I don’t really notice it until having to hear myself speak. I will try and remember how annoying it is from now on.
On a better note, I believe the aluminum sulfate has solved my pains! I don’t know if I’m out of the weeds yet but it’s looking promising! I’m doing what I can to get it back to 100% and start pulling slabs from it.
Thanks for watching
