Spa Test Strip is used for pre and post testing. It helps maintain a good balance of alkaline and acidic water for proper equipment protection and comfort. It also allows maintain a pH balance, ensuring that the pH is maintained in the tank. Both of which lead to healthier, more microbe free water in the spa.
The basic idea behind both methods is to add or remove a specific sanitizer ingredient to the spa water, and monitor what that sanitizer ingredient does to the water. TA is the most commonly used and most effective of the sanitizers. The purpose of a spa test strip is to show if the selected sanitizer is removing the unwanted chemicals from the spa water. The two types of sanitizers are:
PH Test Strips: These strips are used to show if there is alkalinity, total alkalinity, or hardness. They use two different chemicals as additives to the water: Bromine and Chlorine. Both of them produce different results with the water. Usually they will produce a reading of either low pH or high pH. Each of the pH strips has an indicator symbol on one end, while the second end of the strip does not have a symbol.
pH Test Strips without chemicals: When you buy these test strips, read the instructions. Some strips have five different levels of pH, while others only have three. The strips use baking soda, guarana, or potassium bromine as their bromine additive. The same chemicals are used, but they are combined differently. The result is the same - you can't determine how much of each chemical is needed to change the pH. You have to weigh the chemicals to see if it's going to be enough to change the pH.
High-PH Test Strips: These test strips have an indicator symbol that will tell you if the strip is full. Usually the symbol will be red, meaning the strip is almost full. If the strip is empty, it will say "broken". Obviously you wouldn't want to use this type of strip in your spa water because the bromine won't enter into your skin.
Low-PH Test Strips: These test strips have a different formula than the high-PH strips. They will be green, indicating that the strip is very close to being full. However, there will be a small amount of extra bromine, which is what is used to change the pH. Usually the amount of extra bromine is less than that in the high-PH test strips. So, these test strips are better for people who are going to use bromine in their spa water.
Combination Strips: Spa test strips that are designed for combination purposes can be found. Most of the time the chemicals in your spa water will be at their most harmful level when you first get them. This means you need to add some baking soda or a solution to the spa water before you shower or bath. Once you add the baking soda, you can do an immediate PH change. The baking soda also helps to sanitize the shower and bath area.
Spa Test Strip Products are sold in most pool stores. There is a good price for the strips as well. When buying the strips, you can buy them in bulk, but if you're only testing a few pools then it may be cheaper to buy them individually. Always make sure you get your strips from a reputable online pool store, as they are more likely to have the best prices and product selection.
