When summer weather comes around, a favorite outdoor activity for many of us will undoubtedly be swimming. While swimming is wonderfully refreshing, great exercise and can help to keep you fit, it’s important to swim in clean water.
Every pool owner dreams of sparkling clean pool water that is free of living and non-living impurities. And no one wants to swim in a dirty pool. In order to keep pool water clean, you will need to check chemical balances on a regular basis as well as if you need to clean or replace the pool filter replacement cartridge. A chemical imbalance, a dirty or worn filter cartridge, or both, can be the cause of dirty pool water.
If there is a chemical imbalance, it may have to do with the chlorine level present in your pool water. Chlorine is added in the pool water to kill algae and remove other impurities like oil, sweat, etc. that gets dissolved in the pool water from regular use. For that, you will have to test the pool water to determine how much chlorine to add to it.
To know how much chlorine is needed in the pool water first you need to know the amount of water your pool carries.
Stabilized and Un-Stabilized Chlorine
Chlorine comes in either granular or liquid form, but in this article, we will be discussing liquid chlorine. Additionally, chlorine comes in either stabilized or unstabilized form. Each is used for different reasons, so let’s cover that first.
Stabilized chlorine means cyanuric acid is mixed in chlorine to stabilize it. This is done to prevent frequent depletion of chlorine under the effect of UV rays. Unstabilized chlorine is used when the cyanuric acid levels get too high, but chlorine is still needed in the water. It’s important to remember that if you keep adding stabilized chlorine when the cyanuric acid level is high, the pool water will still show low levels of chlorine regardless of how much chlorine you add, so it’s important to test for cyanuric acid before adding any chemicals to the water.
Unstabilized chlorine depletes quickly in sunlight, so it’s a good idea to add it in the evening for maximum effectiveness.
How Much Liquid Chlorine to Add to a Pool?
First conduct a water test to determine the chlorine level. Water test kits are readily available at numerous stores and online, and come with detailed instructions to decipher how to read the results.
An important thing to mention here is that the chlorine that is measured is actually free chlorine, there is no differential.
To determine the amount of liquid chlorine you need to add, first consider the total water capacity of your pool. Most chlorine comes in packing suitable to be used per 1000 gallons of water. If the water capacity of your pool falls outside of that, there are chlorine calculators online to assist you in determining the correct quantity of chlorine to add.
It is recommended to keep chlorine levels maintained between 1 ppm and 3 ppm. Above 3 ppm concentration of chlorine in pool water can cause irritation to the eyes and skin of swimmers.
When adding chlorine, keep the pool pump running for proper dispersion and refrain from swimming until the level is below 3 ppm.
IMPORTANT NOTE! Liquid chlorine is an extremely harsh chemical and must be handled with precaution. It has a higher pH value than the powder form so it is highly likely the pH will need to be re-balanced after adding it. It is also highly corrosive and can cause burns or damage to pool equipment if not used correctly. Always handle any pool chemical with caution and wear protective clothing, gloves, and eye protection.
To get sparkling clean water and a properly sanitized pool you should take care to keep the chemical composition of the water perfectly balanced. Also, check the filter cartridges; dirty or worn cartridges may need replacement. Sta Rite filter cartridges replacement are a good option if the replacement of the filter cartridge is required.
