What you need to consider before choosing a sand filter with your saltwater pool system

Before you choose a sand filter, there are certain things you need to consider. 

1. Pool Size

What is the size of your pool? And yes, it does matter in choosing your sand filter because the sand filter must be sufficient enough to purify the saltwater pool else, you will be at risk of getting an unclean pool. So, it is better if you get a more powerful pool filter if your pool is large.

The larger the pool size, the larger the capacity of the pool filter. For instance, a 20,000-gallon saltwater pool needs a 20-inch sand filter tank to do the job and it goes on in that format. 

2. Check the pool type

What type of pool is it? Is it an in-ground or an above-ground pool? This is because your sand pool may not be suitable for your above-ground or in-ground pool.

However, most pool owners have indicated that sand pool filters are usually better for in-ground pools. But we suggest you look into this for your convenience because sand filters can be good for both pool types. 

3. Filtration energy

You need to also select a sand filter that is capable of filtering a tangible amount of water per hour. Such that it would complement with the pool size and the time invested in running the pool.

So, if for instance; your pool size is about 30,000 gallons, then it means you need a filter that can at least filter about 3,000 gallons of saltwater per day since the pumping time can be around 10 hours.

4. Your location

Your location is also as important as anything else. Because the sand filter is prone to crack or spoilage during frosty climate seasons. So, if you live in a location where the weather is usually frosty, then you need to sort out possible ways of removing the sand filter, and transferring it into the house or somewhere safe since the pool is not in session.

Also, you need to consider that you will need to replace the sand in the filter during seasons like this. So, consider the climatic condition of your location.

5. Cost

Expenses are quite important, and should, as a matter of fact, be the first thing that you should consider while considering a sand filter. Well, this is because even though sand filters are affordable, you need to consider the size of your pool in order for you to know the size and type of sand filter to buy.

And as a result of this, prices tend to increase because of their size. However, you should get ready to spend at least $400 to $1000 on a sand filter in addition to the installation fee.
