Algae ?

[chem geek]

Pool water chemistry school doesn't mean that they know all there is to know nor that everything they know is accurate. Even the NSPF CPO course has some errors and a lot of omissions. I write about this in the following post:

I am also going through the IPSSA Basic and Intermediate Training Water Chemistry manuals and they have similar errors and omissions.

The biggest problem is a complete lack of understanding of the chlorine / CYA relationship which is a primary principle of BBB that keeps all our pools algae-free at low cost.

Sadly, the pool biz is filled with as much mis-information and false advertising as the vitamin and supplement biz.

Ben started this site because the pool industry and pool chemical industry regularly distributes information that is false and mis-leading. Even the EPA has blatantly incorrect guidelines for chlorine levels. Just some examples:

1) you need calcium in your water even with a vinyl pool: FALSE!
2) If you get "chlorine lock" you need to drain your pool and refill: FALSE!
3) Bleach adds to your total dissolved solids and therefore should NOT be used: FALSE!
4) Phosphates are a serious problem and you need phosphate removers if you want a clear pool: FALSE!
5) The bigger the pump, the better: FALSE!
6) Nature2 will save you money by cutting your chlorine use in half: FALSE! (the cartridges cost double the cost of the chlorine you save)
7) You lower Total Alkalinity by using the "Slug" method of adding a lot of Muriatic Acid in one place: FALSE!

That's a sample of 7 things that are pushed on you by the industry that are false and I can think of half a dozen more, easily.
