Unfortunately, it turns out Henderik is apparently a shill for the company, and is trying to improve their Internet ranking. Found the SEO traffic trying to verify this post in my logs tonight!

Otherwise, this all goes down as yet ANOTHER case supporting the general rule that, "If they are trying to sell "oxygen" for your pool, they are trying to rip you off!
