Why Is My Pool Water Cloudy With Baquacil? [Fact Checked!]

Spread the love

Your pool water may be cloudy with a fine powder called BAK (dibutyl ammonium chloride). The cloudiness is usually a sign that there is something wrong with the water quality. It may also be a sign of microbial activity or a sign that the filter is not working properly. A cloudy pool water cannot be considered “healthy” in any way, shape or form, and you should take immediate action to fix the problem. You can do this by calling in a professional aquatic maintenance company to test the water and take care of any necessary repairs or replacements. You should look into the underlying causes of the cloudiness before making any rash decisions. This article will tell you everything you need to know about your pool water’s clarity, including the various causes and the proper way to fix it.

What Is BAK?

BAK is short for dibutyl ammonium chloride, and it is a commonly used quaternary ammonium compound (QAC) that is extremely effective at removing microorganisms from water. It is used in many swimming pools to maintain the health of the water and the pool environment. BAK is available in liquid or solid form, and it is usually found in tablets or granules for easy dissolution in the water. When dissolved, BAK creates a thick, protective coating on the surface of the water that inhibits the growth of microorganisms.

Why Does My Pool Water Become Cloudy With BAK?

When you pour a glass of water in the bath tub, there are usually several layers involved. The first is the surface layer, which is composed of water molecules that are closest to the surface of the water. This surface layer is about one nanometer thick and is in constant motion due to thermal agitation. The next layer down is the bulk layer, which is generally thicker and less agitated than the surface layer. The bottom layer is the gel layer, which is composed of thickened water molecules that are bound together by weak van der Waals forces. Gel layers do not move around as much as liquid layers, but they are still in constant motion due to thermal agitation. The gel layer is only a few angstroms thick.

When you add BAK to the tub mix, it usually stays dissolved in the water for only a short while before precipitating out as solid particles. This happens because BAK is extremely prone to forming insoluble compounds with other substances, and there is usually another molecule available for immediate dissolution. When this happens, the BAK and the other compound will form a kind of “ball” that will eventually settle to the bottom of the tub. When this happens, you have BAK sediment at the bottom of the tub. The reason for this is that molecules of BAK have a tendency to attract other molecules due to van der Waals forces, causing them to form insoluble compounds. This is why BAK tends to stay “suspended” in the water for only a short while before precipitating out as solid particles. Once the BAK settles to the bottom of the tub, it has nowhere to go except up, and this is why it usually stays at the bottom of the tub for the rest of its existence. This is why your pool water becomes cloudy when you add BAK to the tub because the BAK molecules are constantly precipitating out of the water and causing it to become clouded. This is why your pool water becomes cloudy even if you leave the tub for a few hours because the BAK has not had enough time to settle out, causing the cloudiness to remain visible. This is also why your pool water should be cleaned regularly because the BAK can settle out of the water over time and accumulate at the bottom of the pool due to the “buoyancy effect”. This is why your pool water should not be consumed, and it is also one of the reasons that your pool water becomes murky during extreme weather conditions. When the air is humid and warm, the BAK will remain in suspension much longer and will stay at the bottom of the pool for much longer. This is why during those conditions the water becomes “greasy” as well due to the “oily” compounds that BAK creates when it comes into contact with water. The BAK molecules readily react with the water and form compounds that become trapped in the gel layer. This trapped gel layer prevents the water from mixing with other compounds in solution, creating a milieu that is more stable and conducive to life. This is why BAK is usually added to the tub when it is already hot or warm so that the BAK molecules have enough time to come to the surface and settle out before anyone drinks the water.

Where Do The Solids Go Once They Have Settled To The Bottom?

Once the BAK molecules have settled to the bottom of the tub, they will no longer stay dissolved in the water due to their insolubility. This is important because the BAK molecules have accumulated at the bottom of the tub and will no longer be present in the water in sufficient quantities to keep the microorganisms from multiplying. When this happens, the water will become less “sterile” and more susceptible to microbial growth. One important thing to note here is that the BAK molecules do not biodegrade in any manner, shape or form, and they will simply accumulate at the bottom of the tub or pool until they are removed via “filtration” or “suctioning”. This is why the water needs to be cleaned regularly and why you should not consume the water if it is cloudy with BAK even if it does not appear to be contaminated in any way. This is also why you need to check for signs of microbial activity annually during the cleaning process, and if this activity is detected, then the water should be treated with an antimicrobial agent such as chlorine or chloramine. Chloramines are more stable than “free” chlorine, which is why they are more commonly used in conjunction with pool disinfection systems. Chloramines are also more efficient at removing “bugs” from the water because they have a higher “bleaching” (killing) efficacy than free chlorine.

Proper Cleaning And Disinfection Of Pools

The cleaning and disinfection of pools is an important process that involves the filtering of water through various mechanisms such as gravel, sand, or sponge filters. During this process, various chemicals are added to the water to ensure that it is safe for swimming. Most commonly, this involves the addition of a “sanitizer”, which kills the microbes that are in the water. Sanitizers such as chlorine or chloramine also create cloudy water, and this is why they are mainly used in conjunction with BAK in order to achieve greater “sterility” of the water.

When the water is free of microbes, it can then be considered “clean”, and this process is usually referred to as a “de-chlorination”. The excess chemicals in the water are then removed via “waste water treatment” (for municipal pools) or via “solar disinfection” (for private pools), yielding a clean, healthy pool with no visible signs of microbial activity. Pools should be cleaned at least once every week or every other week, and sometimes this process needs to be adjusted according to how many times the pool is used. Pools should undergo this process every year, regardless of whether or not they have been cleaned during the previous year. During this process, the water should be checked for signs of microbial activity and for the presence of any gas bubbles that could arise from decaying matter at the bottom of the pool. If this is the case, then the water should be treated with additional sanitizer to ensure that it is safe for swimming.

When a pool is properly cleaned and disinfected in this manner, it will have the appearance of a bright, clean pool with no signs of microbial activity. Pools are usually cleaned and disinfected just after winter, when the temperatures are at their lowest, which prevents the growth of microorganisms in the water. When temperatures rise again in the spring, so does the growth of microbes in the water, and this is why the water needs to be cleaned and disinfected once more before swimming can take place. This process usually takes place in the summer, when there is the most sunlight, so that the water can rapidly heat up and aerobic bacteria can multiply rapidly.
