2023年12月10日 · Liquid Chlorine. Household bleach and liquid pool chlorine are the two common sources. They are identical in every aspect except strength, household bleach is typically 6%. Pool chlorine typically sold at pool stores is usually around 12%. Avoid bleach that states splashless, scented, or any type of fabric enhancers (i.e. polymers).

Discover the pool calculator behind the perfect pool, PoolMath. Dealing with pools has allowed TFP to become the original authors of the best calculator on the net. To help you better understand the calculator and keep your water clean and clear, you should also view the following: ABC's of Pool Water Chemistry

2013年8月6日 · So is having an accurate measurement of FC (free Chlorine). The Chlorine to CYA ratio is the single most important factor for sanitized water. Using slow dissolving sticks and pucks that contain stabilizer are constantly changing that ratio. For example: The minimum amount of Chlorine for a pool with 50ppm of stabilizer is 4ppm.

2024年11月22日 · This makes the pool water much less harsh for the swimmer's exposure to active chlorine compounds (hypochlorite and hypochlorous acid). It is important to stress this point—the cyanuric acid concentration determines the amount of active chlorine (hypochlorous acid + hypochlorite ion) available in pool water.

2022年6月11日 · Inside the HASA tank at the interface between the water and the liquid chlorine the pH is closer 12.5. That means your CSI is way over +2.0 which will make any calcium in the water turn into calcium carbonate since there is also …

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7月17日 · So pouring chlorine slowly, and perhaps even pre-mixing in a bucket of pool water to dilute it first, may make a lot of sense for vinyl pools. There are PBs who will swear that vinyl pools are destroyed by bleach, but these may be cases where the chlorine is poured in quickly and settles at the bottom of above-ground pools where there is no ...

2025年2月26日 · Pool stores and the pool care industry recommend free chlorine levels from 1–3 ppm that are often inadequate for sanitation and algae prevention. Their recommendations are based on outdated information that only focused on individual chemical levels as opposed to the ways that the different chemicals in your pool affect each other.

2019年1月18日 · A salt water chlorine generator uses electricity to convert salt into chlorine. As the chlorine gets used up, it turns back into salt, ready to be reused. With a SWG, you are still using chlorine, the SWG simply takes care of adding the chlorine for you. The salt levels used vary somewhat between models, commonly they are around 3,000 ppm.

2019年1月18日 · If your FC is 3 ppm or higher, do not add any more chlorine to your pool. If your FC is less than 3 ppm, add enough liquid chlorine to achieve 3 ppm FC, wait 30 minutes, then retest with the FAS-DPD test. The next morning, ideally before there is any direct sunlight on the pool, perform the FAS-DPD test again and record your daytime results.
