2024年7月20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 Their recommendations are based on outdated information that only focused on individual chemical levels as opposed to the ways that the different chemicals in your pool affect each other.

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 …

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 ...

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.

2024年8月18日 · Also, the chlorine/CYA chart doesn't apply the same way in spas as there was a spate of hot tub itch/rash issues, some with Dichlor-only use after 1-2 months with the net result being that it seemed that higher active chlorine levels may be needed to prevent Pseudomonas aeruginosa from growing, especially in biofilms.

2024年12月31日 · Take your chlorine down to 0 and PH down to 7.2; if there is chlorine in the water, it won't hurt; it will just eat up the ascorbic acid, so you will need more to get rid of the stains. Let it decline naturally. Remove tablets, stop adding liquid chlorine, or turn off the SWG.

2023年9月25日 · In the first few days of a SLAM, testing and adding chlorine more frequently can be beneficial to closely maintain SLAM FC level. We recommend 3 times daily at a minimum: morning, noon, and night. If your schedule permits, you may test and add chlorine more often. SLAMing an outdoor pool is most effective when CYA is around 30 to 40.

2023年7月21日 · chlorine clears pools and does not cause cloudiness. The cloudiness can be a reaction to something else in the pool but chlorine (without additives) is not the issue. Your CH is a bit high. It is possible that adding the chlorine temporarily raises the pH just enough to cause some of the calcium to precipitate out.

2022年6月28日 · Using a salt chlorine generator results in the generation of chlorine as well as sodium hydroxide (a strong base) that increases PH. Therefore, if I increase the chlorine generation % of my device, I will also be increasing PH. 2NaCl + 2H2O → 2NaOH + Cl2 + H2 OR Sodium Chloride + Water =...
