So I went back and reviewed that very long thread. I also pulled up the
MSDS for Bio-Klenz as well. Maybe
@JoyfulNoise can interpret those ingredients for us? I'll be honest, I'm a bit skeptical. The OP of that thread struggled for quite some time and IMO there were some questionable issues along the way, or at least in communication throughout the thread some details appeared unclear. AG is a respected expert at TFP and his insight on hot tubs is well known. Some of the Ahh-Some related products have huge benefits for hot tubs, but those have unique demands compared to a pool. Not sure we can put them in the same boat.
What I can say is when it comes to excessive chlorine demand in pools, the
SLAM Process process is 99.9% effective when followed properly. Organic matter simply cannot survive in a body of water that is properly chlorinated, or with an elevated chlorine level during a SLAM. Of course this is your pool so you are free to purchase any try such a product, but before you do I would investigate that cover in the pool to ensure nothing is growing behind it. Keep in mind TFP has coached thousands of pool owners through their algae/organic issue and we never recommend such a product, at least not that I can recall.
Because of your location, I'm also going to tag
@mgtfp and
@aussieta for some local eyes on your issue. Let's put all our heads together to ensure you get all the advice needed to resolve your chlorine demand issue.
A quick re-cap for any new followers:
CYA - 40
FC 16 - falls to about 11-12 overnight
FG pool with no drain or accessories, but does have an unknown cover against one wall (pending examination).
