What Type Of Chlorine For Your Above Ground Pool
Liquid chlorine is often used in large commercial pools and is delivered into large 50-gallon vats. This chlorine composition shows its basically highly concentrated bleach. This is something that is only recommended for use if you know what you are doing as it requires a metered constant drip.
Granular chlorine or shock is typically used for super chlorination or shocking your pool. This form of chlorine is expensive and burns off quickly. The purpose of this product is to dissolve and kill rapidly, then disappear. It allows you to clean up a mess and swim safely shortly after. Using this as your daily chlorination product is not the best of ideas as it will drain your funds quickly.
Shock Pool With Algae
You do not want to see the full extent of damage algae can cause to your swimming pool. The dull appearance and the astronomical drop in chlorine concentration within the pool become even quicker with algae.
Algae consist of a wide range of eukaryotic, phototrophic, and oxygenic microorganisms that use energy and light as a source of growth. Algae is different from plants because they do not possess any tissue differentiation.
Any pool with algae is an eyesore and very much dangerous to health. That is why it is crucial to act fast whenever they are perceived to be within the swimming pool.
However, just a dose of fresh chlorine can eliminate this inimical threat to your pools survival.
These are the main types of algae: Blue-Green Algae , green pond algae, filamentous/string/hair algae, bryozoans, diatoms, red pond algae, chara/muskgrass, golden algae.
The Different Types Of Chlorine
Whether you choose to go with tablet, powdered or liquid chlorine, know that these come in either unstabilized and stabilized variants.
Without turning this into a chemistry lesson, Id like to cover the basics when it comes to the different types of chlorine, and more importantly what each one means for you as a swimming pool owner.

Quick Dip: How To Shock Your Swimming Pool Using Liquid Chlorine
Shocking your pool water is one of the keys to keeping your pool sparkling and ready to swim in. Failing to shock your pool water can lead to algae and bacteria build-up. This creates a swimming pool that is not only uninviting, but hazardous to pool patrons as well. Just because your water is clear, does not mean it is safe to swim in! This is why a high-quality pool testing set from LaMotte or Taylor is an essential part of every pool operators kit!
Shocking a pool with liquid chlorine or a granular pool shock kills or inactivates pathogens and algae. Shocking will also oxidize other unwanted materials inhabiting the pool water. By raising the chlorine level in the pool to the correct level, and holding it there for the prescribed amount of time, this effectively disinfects the water. This article covers shocking your pool with two of the most popular shock products on the market today sodium hypochlorite and calcium hypochlorite .

Does Liquid Chlorine Raise Ph

A: No. It does not raise pH. When dissolved in water, liquid chlorine enables Hypochlorous acid and Sodium hydroxide , which helps the level rise. However, when the Hypochlorous is deflated by UV, it births hydrochloric acid . The rate of this HCl is almost the same as the amount of NaOH therefore, any net effect on pH is nearly nothing or completely zero.

Can You Buy Liquid Chlorine
There are lots of options on the market for liquid chlorine. Prices will vary depending on the brand you choose and the size of the product you purchase. For the strength of the liquid chlorine, you may not need as much as you normally would with chlorine tablets. Most commercial pool owners will use a pool supplies company to have larger containers of chlorine delivered to their location.
Should You Use Liquid Chlorine Or Tablets For Regular Chlorination Of Your Pool
For outdoor pools an ideal combination in the summer months is to use liquid chlorine along with 1 x 3 tablet per week. This will maintain the chlorine levels without raising the stabilizer levels too high.
I wouldnt use chlorine tablets exclusively though as your stabilizer levels will get too high and youll need to drain your pool to remove it.
The amount of liquid chlorine and tablets you use will depend on the volume of your pool.
For indoor pools, stick with liquid chlorine or other unstabilized chlorine.

Is It True That Chlorine Tablets Can No Longer Be Used In Commercial Swimming Pools
Tablets have come under increased scrutiny in recent years. Chlorine tablet use is now highly regulated in commercial swimming pools, given safety concerns due to over-dosing of product over time. For the same reason, discerning pool service professionals and residential pool owners are opting for Liquid Chlorine sanitizer, which has been proven to be both safer and more effective in disinfecting residential pools and hot tubs. Sodium hypochlorite products, such as those marketed by HASA, contain no cyanuric acid that can actually make chlorine less effective to clean and disinfect pool water. Also, there is no calcium byproduct, which can lead to the formation of damaging scale.
Liquid Chlorine Vs Powder Chlorine
Ive taught you all I know about liquid chlorine today, but that doesnt necessarily mean it is the best choice for your pool. That choice is up to you, so heres the basic differences:
Liquid chlorine has a higher pH level than its powder form. It’s used primarily by commercial pool owners or pools with a lot of activity, and it’s cheaper than powder, so when it needs to be added in bulk to large pools, it makes more sense economically.
Liquid chlorine is also unstabilized, so in outdoor pools, you’ll usually have to add cyanuric acid with it to protect it from the sun and to keep it from corroding your pool.
Powder chlorine is a little more expensive than liquid, but it has a lower pH level and you can buy it in stabilized form so that you dont have to add much cyanuric acid, if any, with it. This makes it a little easier to use.
There are a few types of powder chlorine: di-chlor, lithium hypochlorite, and calcium hypochlorite.
They each have their own advantages, but calcium hypochlorite is the most popular and most effective.

Should I Use Liquid Chlorine Or Tablets To Shock My Pool
Liquid chlorine is a much better choice than tablets for shocking. It is going to go to work right away and get your chlorine levels high in a short time. Saying that, it is an expensive way to do it. Calcium Hypochlorite is a much more cost effective way.
Because chlorine tablets are slow releasing, theyre not very practical for shocking your pool. It would take a lot of tablets and a lot of time for your pool to reach a level that would work as a shock. In addition, with chlorine tablets containing stabilizer, your CYA levels in your pool would skyrocket if used as a shock.

When To Use Liquid Chlorine
Liquid chlorine is mostly used in pools that have a high level of swimmers. This type of chlorine will get your pool chlorine levels back to where they need to be faster than other types of granular chlorine. Even though this chemical may seem like the best choice, there are a few things about it that could cause you to think twice about using it.
The first problem is that liquid chlorine has a high pH of 13. When you add products with a high pH to your pool, you will need to add cyanuric acid to your pool to help lower the pH and bring it into range. The cyanuric acid works as a stabilizer to ensure that the products you just put in the pool will stay in place and truly clean it.
Another issue with liquid chlorine can be pits potency. With the choices you have on the market, the liquid chlorine will be one of the strongest, and therefore it can be a bit damaging. If you have a vinyl liner pool, you may notice that the continued application of liquid chlorine is starting to stain or fade the pool walls.
In addition, liquid chlorine has been known to erode and break down pool walls. Typically if you follow the proper procedures when putting the liquid chlorine in the pool, you shouldnât have these issues. Itâs just important to know the downsides of the liquid chlorine before making this the choice for your pool.
What Are The Differences Between Using Trichlor Tablets Vs Liquid Chlorine
Trichlor tablets came to popularity due strictly to a perceived convenience of application, but they actually offer certain setbacks for pool owners over time, as a result of a residual chemical by-product left behind after continuous use.

How Much Chlorine To Add To Pool
The basic chlorine to pool water balance is supposed to range between 1 to 3 PPM. To achieve this pool chemistry balance, you will need about 0.00013 ounces of chlorine per gallon of pool water.
Different swimming pools feature varying sizes. Hence, you will need to perform some simple calculations to figure out the amount of chlorine you need to shock your swimming pool.
To determine exactly how much chlorine to add to the pool, you need to calculate the size of the pool. On average, a round ring pool 15 feet across and 48 inches tall will hold approximately 4,978 gallons of water. On the other hand, an in-ground pool can hold over 31,000 gallons of water.
To determine the number of gallons in the swimming pool, measure and multiply the width, average depth and, length, then multiply the value you get by 5.9 for around pool, 6.7 for an oval pool, and 7.5 for a rectangular pool.
After determining the number of gallons in the swimming pool, the next step is to figure how much chlorine to add to the pool to bring the level to a healthy point. To do this, you will need to use a pool test kit. If you find that the chlorine level is already 1 ppm and you prefer it higher, you will need to add 0.00013 ounces per gallon to raise the level by 1 ppm.
