2024年11月22日 · An outdoor pool under a cage or cover does not need as much CYA as an outdoor pool in full sun. What are the Correct CYA Levels for an Indoor Pool or Spa? CYA is not required in an indoor pool or spa. It does two things: it buffers the harshness of chlorine and protects the Free Chlorine from the sun's UV rays. Bathers can benefit from CYA ...

2011年5月26日 · Use the pool calculator to determine how much stabilizer will add 20ppm of CYA to your pool. That should get you up to about 30ppm which is low for super hot climates but also a good starting point until you can get an accurate reading for CYA. Then, assume you have 30ppm CYA in the pool and set the pool calculator for that number.

2025年2月26日 · With no CYA stabilizer in your pool, FC will be quickly consumed by sun exposure instead of doing its job to oxidize organic material like bacteria and algae. If your FC level drops too low in your pool, you risk allowing algae to grow. The more stabilizer present in your water, the more free chlorine you need to sanitize your pool effectively.

2009年5月3日 · Split off of Increasing CH and CYA, which order and best application. JasonLion I would reccomend putting the CYA in a filter sock, used panty hose, or something similar and place the contents in your skimmer basket. It takes time to dissolve. Pouring it directly into the skimmer and allowing...

2016年7月31日 · Normal FC consumption in a pool is 2-4 ppm per day so it will drop by that amount daily, possibly a little more with higher FC. It is safe to swim with FC up to shock level for your CYA. Shock level on the [FC/CYA][/FC/CYA] is less harsh than a public pool with FC of 1 ppm and no CYA.

2009年5月4日 · The chlorine gets consumed but the CYA stays behind so, sooner or later, you WILL have an overstabilized pool! (FC is normally consumed at a rate of 1-2 ppm per day in must pools but it can be as high as 3-4 ppm during the heat of summer and a lot of usage so it's entirely possible for a pool to go from no CYA to too much CYA in one short swim ...

2007年6月25日 · While my pool is clear...but my brother-in-laws pool is the one in question. He does have an algae problem that he's been fighting all year, which is due to having no measurable amount of CYA in his pool. He recently bought a new container and added that...we'll wait and see what it goes up to. itabb...thanks for your thoughts.

2009年6月17日 · Nevertheless, there is a pool service in Arizona and surrounding states that uses 100 ppm CYA since they only visit the pools once a week and they raise the FC to 14 ppm when they visit and it drops to around 4 ppm when they come again the following week.

2023年9月25日 · SLAMing an outdoor pool is most effective when CYA is around 30 to 40. Below 30 you lose too much chlorine to sunlight. As CYA goes up, SLAMing requires more and more chlorine, which starts to get impractical around 80 or 90. With CYA above 90 we recommend replacing water to decrease CYA before you start the SLAM process.
