Vinyl liner pools are one of the most popular construction methods in Canada for many reasons—one being ease of maintenance. For example, it is harder for algae to grow on vinyl than on plaster. However, even the highest quality vinyl liner is still subject to staining and discolouration. Improper water balance, water treatments, and specific types of debris can cause persistent maintenance problems, most notably staining on vinyl surfaces. This article provides a brief overview of how typical staining occurs to help service professionals take care of these persistent maintenance challenges.
As the weather warms up and the swim season starts, pool water quality begins to suffer and algae often start to grow. Some algae are easy to treat and remove; however, other types can be quite challenging to deal with. The three main types are: green, black, and yellow/mustard algae. Green algae is relatively easy to eradicate, but yellow/mustard and black algae are difficult to kill and, as a result, can make the job of a pool service professional difficult.
Water can dissolve just about anything—from sugar to cement. One thing it cannot dissolve, however, is oil… thus the old adage, “Water and oil don’t mix.” The electrons of the water molecule are similar to those of sugar or cement; therefore, the substance will become soluble at some point. On the other hand, the electrons in the molecules of hydrocarbons such as oil are not similar to water and, therefore, they repel one another.
When dealing with pool stains, it is important for service professionals to keep in mind they are not always cut from the same cloth. Therefore, it is critical to diagnose the problem first before providing a broad-spectrum treatment. Take the time to review the origins of common pool stains and determine what the likely cause is for each specific case before determining how it should be treated and removed. This article will provide a quick refresher for service professionals on some of the more common types of pool stains and what the best procedures are to remove them.
Water is an amazing, mysterious, and powerful element. To understand the capabilities of water and its effect on pools it is vital to understand how it travels throughout the world. The water cycle is a continuous loop of the various ways it transforms and renews itself.
As most in the industry know, the buildup of scale in a hot tub/spa can be a pain. Literally. Once the scale has formed, the only thing left to do is grab a mild scale remover and start scrubbing. After draining and several hours of elbow grease, some progress may have been made and the pain will be over…until next time.
Saltwater systems have become extremely popular over the past five to 10 years. The system’s popularity, however, began with pools, to improve the swimming experience while simultaneously reducing the amount of traditional chemicals needed to sanitize the water. Add to this the safety benefit of eliminating the need to store large quantities of chlorine on-site.
Calcium phosphate scale is a new problem creeping into the swimming pool and hot tub industry. However, the problem has long been recognized in the boiler industry. Calcium phosphate scale became prevalent when reverse osmosis (RO) technology was widely applied to municipal waste water. Due to recent water shortages, municipal waste water recycling and reuse has become a major area where this water purification technology has become prevalent. As such, preventative actions have become commonplace for commercial boiler water and now, it seems, it may become standard for treating swimming pool and hot tub water, as well.
