What to Check Before Buying Best Pool Shocks?
Maintenance of the swimming pool require a lot of effort and the usage of different products. One of such products is a pool shock that helps in deep cleaning the pool water and maintaining the chlorine level.
Here is a quick guide on how to purchase the best pool shock:
1. Type of Pool Shocks
The pool shocks are available in three different types. They are available in granular form which is often recognized as a powdered shock.
This is the strongest category in pool shocks available in the market. This is quick in dissolving and gets burnt by UV rays without increasing the pool’s cyanuric acid level.
The products are sold in regular stores as well as the swimming pool supply stores. You are advised to buy it from swimming pool supply stores because they sell authentic products.
The finest recommendation in this shock is the Zapp It ProPool Shock as it comes with high chlorine content that eats away the bacteria in no time.
This type of shock dissolves rather slowly. It is available in powdered form and lasts for more time in the water.
The formula comes with a stabilizer that increases water’s cyanuric acid level. This can be considered as a shock treatment or for the pool’s chlorine level maintenance.
It is best to use the shock in the evening and swimming can be resumed as soon as the chlorine level is back at normal.
Potassium Mono Persulfate
Basically, this is more like a pool water cleanser because it is based on an oxygen formula that helps in removing the contaminants in the water.
It helps the chlorine to work at its best and keep the pool water oxidized.
In a nutshell, the best pool shock treatment is with calcium hypochlorite. This is a little strong and requires proper attention as you use but it’s highly effective as well.
2. Type of Pools
There are different kinds of pools installed in the households. This gives birth to the requirement of different pool shocks, individually for different pool types. You can only buy the best pool shock for the money if it is compatible with the pool type.
Basically, this is a plastic form made of ethylene and chlorine and thus, polyvinyl chloride is created. The common name for this is PVC.
The material is extruded and long rolls of flexible and thin material are used to line above ground or in-ground pools.
While the pool is made of chlorine, it is important to maintain a level for the pool to retain its plasticity. Over-chlorinating will also cause bleaching of vinyl liners when chlorine sits on the bottom of the pool without dissolving.
There are three types of oxidizers that easily get dissolved in vinyl pools without causing any damage. Also, you don’t have to pre-dissolve them in a separate bucket.
Non-Chlorine Shock This oxidizer contains 100% potassium which is simply a mixture of different salts. This is a safe option to choose for vinyl pools.
You can simply pour it into the pool and enjoy swimming right after. It takes a quarter of the time that chlorine takes to sanitize the pool.
Shock and Swim: In this, calcium hypochlorite is formed with high-pressure compaction and granulation techniques.
As a result, tiny granules are formed that have to be dissolved in pool water. It takes not more than 15 minutes to make water swim-ready.
Lithium Pool Shock: This kind of pool shock has the cleanest burning and fastest action. They don’t bleach the vinyl liners and also leave any messy residue behind.
In the making of this pool, the molded shell of fiberglass is used which is further coated with Gelcoat. The surface is quite durable and less affected by chlorine.
The application has to be careful. This way, you can reduce the staining and fading of fiberglass. Two types of oxidizers are used to treat the pool.
Instant Liquid Chlorine: This is basically a highly granulated form of calcium hypochlorite. While it does require pre-dissolving, it is highly safe and suitable for usage. It is best to safely pour the mixture through the specially designed bottle.
Super Shock & Swim: Super shock is an advanced version of regular shock used in the pool. It has fast dissolving action with balanced pH levels and does not leave any residue.
The pool is made of a gunite shell and covered with a layer of plastic that is waterproof. The plastic is also sometimes mixed with quartz, pebble, or bead to have additional color, strength, and texture.
The usage of oxidizers depends on the composition of the plastic layer. Some effective options are listed below:
Pool Shock: It is the lowly priced pool shock that has around 65% of chlorine in it. Such are among the strongest form of pool shocks. For best dispersion, you should mix it in the bucket and apply it after sunset.
You can use Doheny’s 7701 pool shock as it has got fitting content of chlorine to clean these pools.
Assure Multi–Shock: The finest oxidizer for concrete pools is Sodium Dochlor that has added clarifiers and stabilizers. The oxidation demand is reduced and the pool is protected from active molecules.
Cal-Chlor Sanitizing Granules: Well, this is the most powerful pool shock among all with 68%chlorine. It is a recommended choice for commercial users plus this is available in large packs. This is for instant application for algae and fecal incidents.
