![]() ![]() Not quite as potent chlorine as trichlor, but still strong enough to be an efficient sanitizer and oxidizer. Most of what I have seen on the market in tablet form is 70% strength. That doesn’t make them any safer, it just means you have to handle it accordingly.Ĭal hypo comes in varying strengths, either 65%, 70%, or 75%. So calcium hypochlorite is on the opposite side of the pH scale from the trichlor tablet. Cal Hypo is known as an inorganic form of chlorine, meaning that no other chemicals have been added to the chlorine.Ĭal hypo chlorine tablets have a pH of approximately 11.8 which makes it a very basic, or alkaline form of chlorine. In the industry, we just call it Cal Hypo. Safe handling of Cal Hypo Chlorine TabletsĪnother less common chemical used for chlorine tablets is known as calcium hypochlorite. It is never a bad idea to use gloves when adding tablets to the pool. Extended contact, however, is probably something that is not recommended. Will they burn you? If they are dry out of the bucket, probably not. The high chlorine content and acidic pH, however, make these tablets dangerous to handle without gloves. ![]() So yes, trichlor chlorinating tablets are safe to use in a swimming pool, in fact, they are a great source of chlorine. Being that the pH scale is logarithmic that makes trichlor tablets nearly 1000 times more acidic than our skin can safely handle.ĭiluted in a large body of water, like say…a pool, the low pH and high chlorine content will find a natural equilibrium and if kept within proper ranges will be relatively harmless to us humans. As a point of reference, the human eyes like a pH of about 7.4, and our skin is nearly 5.0. Trichlor chlorine tablets have a pH of approximately 3.0 which makes them a very acidic form of chlorine. Trichlor has 90% available chlorine, which is the highest available chlorine you can get for consumers, which is also why it is such an efficient form of chlorine to use. Referring to a type of chlorine as stable has nothing to do with it being safe for human handling. Trichlor is known as a stabilized form of chlorine, meaning that other chemicals are added to protect the chlorine from being degraded by UV rays, see this article about CYA for more on that. ![]() In the industry, we just call it trichlor. The primary chemical compound used for chlorine tablets is known as trichloro-s-triazinetrione or trichloroisocyanuric. Safe handling of Trichlor Chlorine Tablets Here are some facts about two types of chlorine tablets to keep in mind when it comes to their safe use. The solid form of chlorine such as tablets and granular chlorine can give some a false sense of safety. Like any chemical, chlorine has associated dangers. But, are chlorine tablets safe to use? Why not just put them in the skimmer basket of the pool? What exactly is an erosion feeder? Are there any drawbacks to using chlorine tablets as a primary source of chlorination? Let’s go ahead and answer these questions and dive into the subject of chlorine tablets. While an erosion feeder has a constant flow of water from the pool pump, a floater allows the tabs to slowly erode gradually.Ĭhlorine tablets have gained popularity over the years as a primary source of chlorination for swimming pool owners. Chlorine tablets are designed to be used with both of these systems. ![]() Swimming pool tablets (pucks) are best placed in either a tablet floater or an erosion-style in-line chlorinator. Let’s talk about where you can safely leave chlorine tablets in your swimming pool. As a swimming pool service professional of more than fifteen years, I have seen a number of scenarios, so in this article, I would like to offer some clarity with factual data as support, and I would like to dispel some of the myths and incorrect instruction that has been offered on blogs, vlogs, and social media sites and other forums out there. The subject of where to leave chlorinating tablets safely in a swimming pool has been a source of confusion for swimming pool professionals and owners alike. ![]()
