All swimming pool owners want to maintain the quality of their pools. If you have the right pool filter, the pool water will remain clean and hygienic. You can choose the best option by checking out the pool filter size chart. When the pool filter is not convenient it is crucial to ensure the safety of your swimming pool. Many people purchase a bigger filter thinking it will work well. However, it is not a good option and can be a threat to your pool. Large pool filters can be expensive and can deteriorate the quality of the filter system.

How to Choose the Right Pump Based on the Pool Filter Size Chart

If you want to maintain the quality of your swimming pool, choosing the right size of the pump is important. When you choose a bigger size than usual, it can be costly. You can measure the size of your swimming pool and purchase the product easily. When you have a medium or small-sized pump it can help you lower your energy bills. Your pool must function properly. This will help keep the bacteria and algae away.

How to Choose the Right Size of Filter

When you have the right-sized pump, your pool will remain clean. Many people purchase a small-size filter but it will generate a lot of pressure on the filtration system. It can even cause the filtering material to break down. While the filter may become ineffective too. There is no doubt it can build up some pressure in the pump. Moreover, it will be difficult for the filtration system to filter out dirt and dust. The small fibers can build up in your pump resulting in damage to the entire system.

Formula for Calculating Pool Depth

It doesn’t matter what the size and shape of your pool area are. All you need is to calculate the average pool depth without any difficulty. It is not difficult to calculate the average pool depth with the pool filter size chart. You have to use a simple formula and find the average between them.

The formula for getting your result is not difficult. Pool owners can find the shallowest and deepest part of the pool. When it is done, you have to find an average between them. Suppose the deep end is 12 feet while the shallow end is 4 feet, the depth will be 12+4 = 16 and 16 ÷ 2= 8.

How Much Water Does Your Pool Hold?

If you want to pick the right size pool filter you need to think carefully. You must determine the amount of water your pool holds. This is an easy-to-handle process especially if you have a rectangular pool. In any case, if the design of your pool is intricate, it can be difficult to handle. There are around for different shapes of the pool that include the following:

1. Rectangular pools

You will have to measure the length and width of your pool first. All you need is to remember the formula from your elementary school which is A=L x W (Surface Area= length x width). You can use it to find the surface area.

When it comes to the average depth you can multiply the average depth by the surface area. It will give you the total volume. Or you can wrap it all into one formula by using L x W x D = V. This happens to be the volume of your pool. If your pool is L shaped you have to add the volume together.

2. Round pools

If you want to determine the surface of your pool it will require a different formula. The surface area will be (SA) = pi (which is 3.14) x the radius squared (r2). So now the formula looks like SA = 3.14 x r2. The next step will be to calculate the average depth of your pool. Make sure you multiply it by volume.

3. Oval pools

There is no doubt that oval pools are difficult to handle. You will have to measure the longest and shortest diameter along with the average depth. The formula for this calculation will be longest diameter x shortest diameter x average depth = volume.

4. Kidney shaped pools

To determine the right size of pool filter, you will have to find the longest and shortest width of the pool. Moreover, you need to understand the length of the pool too. Kidney-shaped pools are different as compared to other types of pools. You can use this formula to calculate the volume: Volume = (longest width + shortest width) x length x average depth.

Method to Determine the Right Pool Filter Size Chart

Here is another method to determine the right pool filter size.

1. Gallons per minute

Once you are done calculating the total pool capacity in gallons, the next step is to calculate the gallons per minute. This will show you how much a pump can handle. Most pool owners try to run their pool for more than 8 hours. It is necessary to determine the gallons per minute first.

2. Feet of head

All pool owners must take a lot of things into consideration. The piping between the pool and pump is known as the feet of the head. If you have more of it, GPM will automatically decrease. Apart from that, you have to take into consideration all the fixtures and valves present inside the piping. You must have a rough estimate of the pipes between the pump and the pool.

3. Choose your pump

It is necessary to know the GPM and feet of the head before you start hunting for the right pump. You can choose a reliable pump that offers the best solution for your swimming pool. The GMP capacity of the pump is not very difficult to calculate.
