Baquacil usage?

[waterbear]

Okay,

I have had pools for several years and have learned a tremendous amount from these venerable pages!

I just had an in ground kidney shaped pool - about 17,000 gallons put in and the construction company started me on Baquacil. I know I know, I didn't know about these pages before then, so based on the fact that it's already there, I'm determined to give it the old college try.

If you are interested, I will keep everyone here up to date on the progress of the pool.

I do have a question or two though. The pool company, and brochure are recommending the following:

1. Algistat & Santizer: Polyiminoimidocarbonly-iminoimidocarbonly-iminohexamethalenehydrochloride.

Is this POLYQUAT?
Did a web search and found out for you that it is a synonym for PHMB (biguinide, BACQUACIL, REVACIL, SoftSwim) as I suspected!
Here's the link

2. Algicide: Ammonium Chloride
DIMETHYL BENZYL AMMONIUM CHLORIDE is a quaternary algaecide (the stuff that foams---not polyquat--and probably what they are referring to (SoftSwim algaecide is listed as 40% Quaternary Ammonia Compound on the BioGuard website, Revacil uses polyquat according to the MSDS on the Mareva website, Bacquacil has 3 different algaecides...no idea what is in them)
3. Oxidizer: Hydrogen Peroxide.
Standard oxidizer for biguinide!
That's it, they also recommend backwashing with Sand Filter Cleaner 2x per year, adn the sand should last 3 years.
Revacil says once a year, Bacquacil says twice a year, Softswim doesn't say (sort of expect that from Bioguard)
I don't see PHMB anywhere in here.....no Biquinide......

Just a fancy chemical name for biguinide to confuse and make it sound very impressive, i guess
Hope this info is helpful!
