Clearview 3″ Jumbo tabs
Slow dissolving and stabilized. For use in erosion-type chlorine tablet feeders. Water flows over the tablets slowly, providing a constant chlorine feed rate. With proper chlorine residual one tablet treats 8,000 gallons every 7-14 days.
Shock Treatment / Super chlorination – How to properly shock treat a swimming pool
Shocking a swimming pool refers to the application of large quantities of chlorine (super-chlorination), non-chlorine shock or hydrogen peroxide. Typically 5-10 times the normal dose is used, based upon actual conditions and needs. The purpose of this large dose is to break down the combined chlorine, organic waste, and contamination and re-establish a positive level of Free Chlorine. Shocking must be repeated, until such time as a stable Free Chlorine reading can be achieved, for at least a few hours. Make sure that a Free Chlorine capable test kit is being used, in order to know when breakpoint chlorination has been achieved. Dragging out this process will only serve to increase the amounts of chemicals required.
Products such as liquid chlorine, sodium dichlor, lithium and calcium hypochlorite, non-chlorine shock and compounded products are used for this purpose.
A pool should be shock treated at the first signs of algae, after heavy rainfall, after periods of heavy bather usage and at the onset of a loss of water clarity or quality. Another common practice is to shock treat the pool every Sunday evening. Typically, this is after a period of high bather demand and will help to re-establish the sanitizer level. A periodic shock treatment helps to prevent the development of sanitizer-resistant microorganisms.
Which Shock Treatment To Use?
There are many different types of shock available, is there a best choice?
The purpose of using a shock treatment is to quickly boost the free chlorine level, usually because of algae problems or high combined chlorine readings.
ClearView shimmer-N’Shock is Sodium dichlor. Fast-acting for super chlorination to control bacteria and algae. Perfect for all pool types, including vinyl and above-ground, as maintenance or shock. pH neutral, will not cloud water, and quick dissolving, 1 pound treats up to 10,000 gallons. Compatible with all treatment systems: chlorine, bromine, copper, silver ionization and chlorine generators. However, it contributes cyanuric acid (CYA) to the water, with each addition. It should not be used, as a shock treatment, if trichlor is being used as a sanitizer or if the cyanuric acid (CYA) level is 100 PPM or higher.
Lithium hypochlorite or Liquid chlorine are the most universal, as neither contributes any unwanted byproducts. Lithium hypochlorite is a convenient, quick-dissolving granular product, but will cost more to use. Both, liquid chlorine and lithium hypochlorite will tend to raise the pH. Check the strength of the sodium hypochlorite. Big box stores appear to be a less expensive choice but are usually are 1/2 the strength.
ChlorFREE 15 is a non chlorine shock. Swim after treatment in as quick as 15 minutes. A
neutral buffered potassium monopersulfate compound that provides superior oxidizing for sparkling clear water. Turns chloramines into active chlorine. Chlor free is non-chlorine and non-bleaching. Compatible with all treatment systems: chlorine, bromine, copper, silver ionization and chlorine generators. Will not raise chlorine to unacceptable levels.
Calcium hypochlorite is cost effective but will increase the calcium hardness of the pool water, with each application. It would not be a good choice if the pool water hardness is 250 PPM or higher. This is NOT a good choice for Southern Utah’s hard water. This is probably the shock that is used most from pool owners that buy their chemicals in a big box store. We do not offer this shock at TROPICAL POOLS.
