Just wanted to let you all know with your recommendations we are doing great! The pool is clear and we are feeling more confident.
Our CYN levels are on their way down, just from splashout or backwashing & refilling. 160 down from 200. So we are still keeping our chlorine higher based on the best guess chart.
We got rid of our algae with polyquat and plan to keep it that way!

Our Ph is starting to creep up to about 7.5 but it looks like that is still in your recommended range.

Is there anything I need to be concerned with on the Ph front with a vinyl liner? I didn't exactly understand your page about running high Ph is ok, sometimes, but not always. I guess I'll just keep us between 7.2-7.6 because of our vinyl liner.
Thanks again! I hope others can learn from this post & gain confidence in trying the BBB method no matter what others are telling them. So glad I found the forum & website!
