It is working! It is working! After 2 days of aeration with my rigged fountain, the pH went up to 7.8. I added more dry acid tonight. I only have a bit left. I will see how low I can get it with this method, let the pH raise to about 7.5 again and just leave it. There are only about 5 weeks left anyway.

Now I need an extra hose so I can run the surface skimmer with the "aerator."

I am sooo prepared for next year!
