It does not matter if you have a swg.
The TFP method is superior in that it empowers the pool owner to very specifically and easily maintain clear and sanitized water without unintended consequences or reliance on overpriced and often ineffective elixirs.
It’s the difference between taking a multivitamin to make disease go away versus having a blood test and specifically treating a disease with a known cure.
It is the difference between driving without glasses and driving with your glasses on
You get the idea.
That’s because TFP was founded on science that shows the relationship between cya and free chlorine — a ratio that should be kept at 7.5% to avoid unsanitary conditions and algae. Some of our founding members worked on research that is now commonly presented, discussed and adopted in the pool industry by associations.
The pool chem industry has been slower to adopt this science (although in recent years many in the industry are beginning to acknowledge this irrefutable research) because they have a dilemma. The products the produce for client convenience require cya to be stable and saleable...chlorine on its own cannot be made into powder format without either calcium or cya. But they feel customers won’t test and dose liquidchlorine daily...they demand products that are slow release and storable.
And just about every other product now manufactured is in response to problems that arise out of this “convenience.” Eg. Algaecide, enzymes, cal hypo Shock, etc. All designed to solve problems created by having too much stabilizer/CYA built up and not enough proportionate free chlorine.
So in truth, if mfgs supported TFP, they truly wouldn’t have much left to sell...just trade liquid chlorine, sequestrants, and maybe calcium. You can imagine what that would do to their profits.
TFP advocates only adding what your pool needs when you need it, and avoiding adding products for which you do not know the ingredients or their effects. That is what keeps TFP pools trouble free. If you always maintain your pool according to [FC/CYA][/FC/CYA] then like me, you will truly never have to shock/slam
SLAM Process your pool again.
5 min a day to keep you and your loved ones protected from waterborne illness, to avoid the hassle of algae, and to enjoy crystal clear water. It’s truly worth the learning curve imho
