What pH is Best for Pools?

Experienced service techs know that the pH in many of their pools generally rises above 7.8 within four to seven days following chemical treatments.  It is a chemistry reality that when water contains 80 ppm to 120 ppm of carbonate alkalinity, and is left alone and untreated by additional chemicals, the pH will rise to 8.0, and sometimes as high as 8.4 and stay there until chemically treated again. 

What does this mean?  It means that thousands upon thousands of residential pools are…

How White Pool Plaster Can Turn Gray

One would think that when mixing white cement with white limestone aggregate, the final pool plaster product would always be white. But that is not always the case.

Unfortunately, white pool plaster sometimes turns gray (or grey) either immediately or a few months after the pool is filled with water. So what causes that to happen?

The concrete/cement industry has documented that late hard troweling can cause a cement surface to darken, mottle, and spot. Also, adding a high…

Why White Pool Plaster Can Turn Blotchy

Both white pool plaster coupons below have been in water for one year. Sometimes the water was slightly aggressive (negative LSI), and sometimes the water was slightly scale forming (positive LSI).

The top coupon was formed with only one percent calcium chloride (CC) added to the mix, and was properly troweled.  It remained a “uniform white” the entire time. 

The bottom coupon had 3% calcium chloride (CC) added, was late hard troweled, and also received some wet (water)…

The Pool Industry Being Duped - Pool Owners Being Scammed

Years ago, pool service techs learned that aggressive water etches quality plaster surfaces uniformly - that it does not pick and choose some areas of the surface to etch, while leaving other areas untouched.

The cement/concrete industry documented that improper workmanship practices can cause cement surfaces to mottle, darken, discolor, deteriorate, streak, and spot.

Yet, in the 1980’s, when pool plastering companies began seeing white spots in some of their recently plastered…

Salt Pool Blamed for Plaster Cracking and Nodules

When a new white quartz pool in San Diego developed numerous shrinkage cracks and very rough and sharp calcium nodules everywhere, the plasterer drained the pool and sanded it, charging the pool owner one thousand dollars for the work. The crystalline nodules began to form again soon afterwards, so the plasterer told the pool owner that a pool plastering expert and consultant would perform an inspection to determine the cause.  The plaster inspector was also a long-time National Plasterers…

Mom and pops are crumbling, the customer is loosing!

NPC Contradictions - What's a Service Tech to do?

On one hand, the National Plasterers Council (NPC) claims that alkaline (positive SI) water during start-up causes a blotchy and smooth gray discoloration you sometimes see in new white plaster pools,1 and that an acid treatment (zero alkalinity) for a week is necessary to lighten the discoloration.2 Yet, hundreds (maybe thousands) of new pools are filled with hard tap water every year and don’t turn gray.  

On the other hand, the NPC also says that aggressive…

"Contesting" Your Success



I have been targeted by a lot of contests lately, and I have to tell you, I find it quite exciting. When I have a chance to win something...and it can really be just about anything...I all of a sudden have a strong and fervent desire to WIN!

Wall Street Journal Responds To "Trashing Pools" - Mentions APSP

Below is the Wall Street Journal editor response to the letter I sent regarding the article they posted titled "Taking a Bath On Your Pool".



Since writing my reply I have spoken to the APSP and determined the data they referenced was supplied by PK Data. If this is the data being provided we should seek to verify that the data is accurate. But the data is only part of the issue. The article was written to be a "ROI" article, yet makes statements… Continue
