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.

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.

Stabilized Vs Unstabilized Chlorine

Stabilized chlorine is that which comes with cyanuric acid as part of its ingredients. Cyanuric acid is also known as a stabilizer, and it will help to keep the chlorine from losing its effectiveness so quickly. When you use unstabilized chlorine, it will have a much shorter time in the pool before it starts to lose its effectiveness.

Many people then wonder why it would make any sense to use unstabilized chlorine. The reason behind this is that you are using too much stabilized chlorine your pool could reach a point of chlorine lock. This is when the choline you are putting in your pool is no longer working to keep the pool clean.

In addition, some pools, like indoor pools or those in the shade most of the time, will have some issues with the sun not burning off enough chlorine. So essentially, if you use stabilized chlorine in these pools, your levels could remain too high at all times. You can avoid this issue by using unstabilized chlorine in the indoor or shade-covered variety of pools.

It is important to know that while outdoor pools do need cyanuric acid, too much will actually make your chlorine ineffective. So, if your pool already has high CYA levels, it might be a good idea to use a chlorine that contains no stabilizer, such as liquid chlorine, until your CYA levels drop.

    Liquid Chlorine or Granular Chlorine Compared – Shock Your Pool

    chem geek said:You can use rains to dilute the water even with the cover on — just feed the water from the top of the cover into the pool that then overflows to a drain . That’s what I do over the winter, mostly to keep salt levels in check. One has to be a little careful since the pool water can get dirty from what is pumped on the cover, but it’s not too bad .

    chem geek said:Once you’ve killed off any nascent algae growth, then maintaining a minimum FC of around 11 ppm with the 150 ppm CYA would probably have a low chlorine usage losing only 15% or so per day so perhaps 1.6 ppm FC per day. The higher CYA level protects chlorine loss from sunlight even with the proportionately higher FC level. The main risk is if you ever have to SLAM the pool — it will take extraordinary levels of chlorine to do that. This is why we normally say that 80 ppm is a maximum CYA level.

    Does Liquid Chlorine Contain Stabilizer

    Liquid chlorine is an unstabilized chlorine and does not have any stabilizer in it. This means that if used in a pool that is located outside and the water has no stabilizer or conditioner already in the water, the UV rays in the sun will degrade the chlorine in about 9 hours.

    This would mean you would need to add more liquid chlorine manually to your pool after each full day of sun. Obviously this isnt ideal for practical reasons or for your wallet. Thats a lot of trips to the pool store.

    The solution is to make sure you either add a stabilizer like cyanuric acid or in addition to using liquid chlorine you use a stabilized chlorine tablet like Dichlor or Trichlor.

    Clearwater Chlorine Granules 5Kg Bulk For Pools And Spas

    After cleaning the pool and adjusting the pH level, you have to proceed further to add the chlorine into the pool. Most of the shock treatment packages will direct you to add 1 lb. of shock per 10,000 gallons of the pool water. This can be fine for any normal conditions. But if your pool is severely attacked by algae, then you will need to take other steps.

    The best technique for the pools that are severely attacked by algae is to provide shock treatment unless until the water of the pool starts to turn blue-ish. Here is the chart that you have to use for shock treatment based on the color of the pool.

    For light green pools, use 1 lb. of shock treatment per 10,000 gallons of water. So, for 25,000 gallons of water in pool, use 2.5 lb. of shock treatment.

    For medium green pools, use 2 lb. of shock treatment per 10,000 gallons of water. So, for 25,000 gallons of water, use 5 lb.

    For dark green colored pools, it is better to use 3 lb. per 10,000 gallons of water. So, for 25,000 gallons of water, you have to use 7 lb.

    So, if you had a question in your mind regarding how much liquid chlorine to shock a pool with algae, you probably have now gotten the answer. Youll have to calculate the amount of water you have in your pool and determine the color of the pool.
