Hello, I am a State Certified Commercial Pool Builderin Florida. If you have any questions, please shoot me an email.

Welcome, This site is a great place for information. I am a CPO Instructor and a State Certified Commercial Pool Builder in Florida. I have some great pool service & construction videos on my site. thepoolpros.com

where are you from Florida? Im from the Ft Lauderdale Area.

Chlorination + Filtration = clear water. My recomendation is never to add any of the expensive algacides. Save your money and use chlorine, stabilizer (enough to protect your chlorine from UV destruction), Bicarb and if necessary Calcium. This with proper circulation(meaning ALL of the water...

When combined chlorine is formed it will eventually off gas into the atmosphere, which is the chlorine smell. Whe you have a cover on the pool, it is preventing, or slowing down the provess. By achieving Breakpoint chlorination will speed up the process of the offgas.

The pH of most of the human body is 7.35 - 7.45. Im not sure why they recommended this, except for the higher levels of HOCl as mentioned above.

as far as the breakpoint calcuation, it has become very unclear between different editions. The best description/explanation I have read is on Robert Lowry's Pool Chlorination Facts where he talks about multiplying the combined chlorine by 7.6 to determine the correct amount of FAC to add to...

thank you for the great info. The main reason I wanted to join this site. Chem Geek, i never said that CYA was a strong algacide, I just said it can be used as one. Because its effects when combined with Amonia and chlorine, whcih will create a type of a chloramine, which is a weak algacide...

Re: Informed noob using Borax! Thats what I thought too until I took a few college level chemistry classes and then ran accros this powerpoint from the CDC. http://thepoolpros.com/webfm_send/94

Split off of I just added 20 Mule Borax to my pool a week ago. It was fine where it was originally, but has now spawned a whole new discussion that is off topic for the old location. JasonLion You want to keep enough stabilizer to protect your chlorine levels. 10ppm of stabilizer will protect...

The problem, is because you have what they call "copper fallout" this is because of levels copper ions in the water, eirther by an algacide(yucky), a gas heater, or the source water you are adding. This problem can be solved by addidng Jacks Magic Blue Stuff. 1 quart per 10,000 gallons...

Split off of Chlorine/CYA Chart. JasonLion Im not sure the relavence of this chart. the key is to protect the chlorine that you put into the pool. 10 ppm of cyanuaric acid will protect 1.5 ppm of chlorine from the UV destruction of the Chlorine Molecule. The 1/2 life of Chlorine when...
