If you saw the title of the article and you are here reading it thinking that we are going to tell you that you do not need to shock the pool, then you misinterpreted the intent of this article.
A big problem associated with shocking the pool is that too many pool owners do not shock their pools often enough. But perhaps the biggest problem associated with shocking the pool is that too many pool owners do not use enough shock when they do shock their pools. When you don't use enough shock, the shock you added will do nothing...that is simply throwing your money away. So yes, there are times when shocking the pool is a waste of money.
When your water looks good - when its clean and clear - and when you have an ideal sanitizer level and you're merely shocking the pool as part of your maintenance schedule, then you can largely follow the label instructions and add one pound of shock pound per x-gallons of water.
NOTE: x-gallons is typically 10,000 gallons or 15,000 gallons, depending on the chemical manufacturer, the type of shock, and the amount of available chlorine within that shock product.
For example - using a 30,000 gallon pool in the example:
Again, this is for when your water looks looks - its clean and clear - and the sanitizer levels are ideal and you're shocking the pool for maintenance purposes.
But what about when the water is not clear? What about when the sanitizer level is not ideal?
This is where a test kit will really really help you. In fact, every pool owner should be using a Taylor test kit to test all of their chemical levels. A Taylor test kit will tell you if you need to shock; and if you do, some simple math will tell you how much shock to add.
When the water is unclear and the sanitizer level is not ideal, you will need to shock the pool to reach breakpoint. Rather than engaging in a prolonged and boring science and chemistry lecture, just let it be understood that reaching breakpoint is adding the amount of shock needed to revive your sanitizer when the water is unclear and the sanitizer level is currently not within its ideal range.
We can teach you how to shock to reach breakpoint when your pool water is unclear.
When you shock the pool to reach breakpoint, you must use the amount of shock required. If you just use 1-2 pounds of shock but your pool requires that 5 pounds of shock or perhaps more are needed to reach breakpoint, then whatever shock you added to the pool will do nothing of real value; it may do nothing at all...except waste your money.
If you just add an arbitrary amount of shock without knowing how much shock you need to add, then you just wasted the shock that you added and therefore wasted your money. While there are plenty of ways to save money as a pool owner, skimping on shock is certainly not one of them. You must use the correct shock and the correct amount of that shock.
If you under-shock, then it is virtually like you did not even shock the pool at all. When you need to shock the pool - and you will need to shock the pool often each year - then make sure to use the required amount of shock. We can get you the correct shock and the correct amount of shock.
