As the summer of 2014 nears its mid-point, drought-stricken areas of California, Arizona, Nevada and Texas continue to place an ever greater emphasis on water conservation. States, counties and cities in arid regions are implementing drought reduction regulations. Many of these are restrictions on the draining and re-filling of pools as well as chemicals being used in the water. Below are some tips for pool professionals to help keep the water quality at its best and reduce the need for pool draining and refilling.
• Reduce Evaporation!
In warmer and dryer areas the annual rate of evaporation can be as high as 6-8 feet per year. When water evaporates, only pure water escapes the pool, leaving behind minerals and chemicals. The faster the evaporation rate, the faster the build-up of solids in the pool, leading directly to the need for draining and replacement of chemicals.
So not only does evaporation mean the direct loss of water from the pool, it degrades the remaining water and hastens the day when that water will have to be intentionally drained.
Many regulatory agencies in drought regions are requiring the use of a solid cover or a liquid cover to reduce evaporation water loss. Solid covers are very effective at reducing evaporation, and even a liquid cover can reduce evaporation up to 50 percent.
• Manage Hardness and TDS
There are certain chemicals that will affect Calcium Hardness and Total Dissolved Solids (TDS) more than others. For example, Calcium Hypochlorite leaves calcium behind in the water, which can build up over time and advance the need for draining. During times of drought it may be advisable to avoid the use of Calcium Hypochlorite based shocks.
Tri-chlor or Di-chlor will leave behind cyanuric acid so it may be best to avoid these as well. Any form of chlorine or shock will leave solids behind in the water. While this can’t be avoided, it is best to try to avoid what may lead to a more immediate need to drain and dilute. A better option for shocking in drought-stricken areas may be liquid chlorine or a non-chlorine shock.
• Keeping Phosphates Low Can Help
Phosphates are a part of TDS so if phosphates are regularly lowered then TDS build-up will be reduced. Higher phosphates can lead to many water quality problems that advance the need for draining and more frequent backwashing. Thus a phosphate removal product can help keep phosphates in check and improve the overall water quality.
• Proactive Removal of Organics
Another vital way to ensure quality water is to proactively remove the build up of non-bacterial contaminants using a clarifier. Efficient removal of organics and suspended materials helps to keep the water clear and ensures that other chemicals are free to complete their intended purpose.
• Remove More Add Less
In drought times the water care mantra needs to be “Remove More, Add Less.” When using any chemical, stop and ask yourself: What is this leaving behind in the water? Oxidizers, clarifiers and phosphate removers are all products that improve water quality while removing contaminants that can cause problems. Avoid over-chlorinating as much as possible. Be aware of how chemicals effect water balance, and choose chemicals that are more neutrally based. Also, avoid cleaners and metal products that contain phosphates. As a pool pro taking the time to be proactive and aware of how chemicals affect the water will help you get through drought times with minimal need for draining.
The 2008 Summer Olympics in Beijing was a highlight in the swimming world — 24 world records were broken and Michael Phelps took home eight gold medals. These events were held at the Beijing National Aquatic Centre, colloquially known as the Water Cube.
Despite the grandeur of the Olympic games, the...
A sand filter is filled with sand, right?
That used to be true, but more pool professionals across the country are filling sand filters with a granular mix of crushed, recycled glass — despite its higher cost. Reasons for this media migration range from performance to convenience to the desire to help the planet (or at least make customers feel like they're helping the planet).
AQUA spoke with three pool companies across the country — one from the West, one from the East and...
Although some members of the industry are unaware of the fact, the U.S. government regulates pool and spa chemicals and sanitizing equipment through an involved process designed to ensure these products’ safety and efficacy. It’s helpful to know something about the regulations and the process by which manufacturers achieve approval (registration) for their products.
The EPA is the branch of government that handles this function. The Agency refers to organisms like algae, bacteria...
