Step 3 – Record these numbers in the spa section of your notes.Typical spa depth is around 42 inches of water.

Step 2 – Measure the depth by using the tape measure at the center of the spa bottom up to the water level.

Step 1 – Measure the total diameter of the spa and divide by 2 to get the radius.

Step 5 – Use our pool volume calculators above with the numbers you have to get the total water volume capacity of your pool.Įllipse, Oval, and Irregular Circular pool shape measurements:.

Step 4 – Record all of these measurements into your notes about the pool.

Use your tape measure from the bottom of the pool up to the water surface.

Get approximately above the deepest point.

Step 2 – Measure the total width of the pool inside wall to inside wall.

Step 1 – Measure the total length of the pool from the inside wall to the adjacent inside wall.

This can also be used for measuring square & rectangle spas. Hence, you will need to perform some simple calculations to figure out the amount of chlorine you need. Different swimming pools feature varying sizes. To achieve this pool chemistry balance, you will need about 0.00013 ounces of chlorine per gallon of pool water. Note: Areas of the pool that are cut out from the main shape will need to be added in to the measurements. The basic chlorine to pool water balance is supposed to range between 1 to 3 PPM. Rectangle & geometric pool shape measurements: If your calcium hardness and cyanuric acids levels are too high, you can decrease them by adding fresh water. Any adjustments made to chlorine or alkalinity do have an effect on pH. Now that we have the tools needed to measure the pool, let’s actually get those measurements, here is how you do it. If you are adjusting for more than one chemical, make additions in this order: Calcium, Chlorine, Cyanuric Acid, Alkalinity, and pH.

You might need a second person to help hold your tape measure.

A tape measure (that is at least 35ft long).

Here are the tools you will need to get all the measurements: The only thing keeping those contaminants from turning your pool into a black lagoon is a sanitiser, and in order for the sanitiser to work, other water attributes must be balanced: pH, alkalinity, and calcium hardness.Now that you have a means of keeping notes on your pool, let’s begin with “How to measure your pool for water calculations”. All you have to do is enter in the respective numbers and the app will magically output the ideal levels you should have to balance the various chemicals in the pool. To calculate if your swimming pool water is balanced check out our Langelier Saturation Index (LSI) calculator. Balanced water has just the right level of pH, Total Alkalinity, Calcium Hardness and dissolved solids in relationship to its temperature. And every time someone swims, they leave behind body oils, hair, dead skin, shampoo.etc. Simply stated, water balance is a term used to describe the ideal condition of pool water. Both are bad for you, your pool equipment and the surface of your pool. The method you use to calculate the volume of your pool depends mainly on the shape of your pool. This calculation will give you the volume of your pool, which refers to the number of gallons that your pool is able to hold. If your water is not balanced it will either become corrosive or form stains and scale. When you identify the exact cubic footage of your pool, you should then multiply the number by 7.5. You are effectively trying to keep your water chemistry stable at all times, either in regular calculated doses or by monitoring a level and balancing it. We know how daunting and convoluted these pool chemicals can seem in the beginning, but once you understand the reasons behind it you’ll see Pool water chemistry is actually quite simple – it’s basically a balancing act of regular treatment. Not only it's crucial in keeping your pool clean and healthy, it's also important that you a lways consult the pool manufacturers guide to ensure your warranty is not voided because of poor water balance. The accompanying Pool Chemistry Calculator allows you to input results from your pool test kit and calculate the required amounts of chemicals to return. Maintaining the right chemistry in your pool water could be the most important job you’ll have as a pool owner.
