Do You Need to Change Your Swimming Pool Sand?

Do You Need to Change Your Swimming Pool Sand? 


This might be a question you are asking yourself if your sand filter is not filtering the swimming pool water correctly.

Well, how do you know that the filter is getting clogged and not working properly? Well, you know by the condition of the water.  If you think it’s time for a sand change, then it might be good to first understand how a sand filter works.

With a sand filter, each grain of sand (not beach sand) has special features that attaches to the sand to the dirt in the swimming pool water. As the water passes through the filter, the sand filters out any particles in the swimming pool that should not be there. The small pieces of debris attach to this special sand and are removed from the pool water. After all, you don’t want to swim in a pool full of debris.

The sand that is put in a pool filter is specifically pool sand.

If you were to use regular sand in the filter, it might destroy the filter.

Time for a Sand Change
It may be time for a sand change when you notice that the filter is taking a long time to filter the pool water.  Or, if you turn on the filter and the water gets clogged up quickly. This most likely means, it is time for a sand change.

A sand change is a time consuming process. When your pool professional tells you that it is time for a sand change, you need to plan a few hours for the sand change.  The pool professional will have to remove all of the old sand and replace it with the new sand.

Make sure that your pool professional fully empties out all the old sand and then rinses out the filter completely before putting in the new sand.   You don’t want to have any of the old sand combining with the new.

And, it is wise to wear long yellow rubber gloves.   The sand filter bowl is made of fiber glass. You want to wear gloves because if you don’t, your arms will itch and your skin will feel tingly from the fiberglass.

I know from experience that it is better to wear the long yellow rubber gloves.

Changing out the sand in a sand filter is a messy process. But, once it is complete, your filter should b much better and you will have clean pool water.

If your sand filter is more than 12-15 years old, than a sand change may not solve your problems.  You may need to just go ahead and install a new filter.

If money is an option, go for the filter. A sand change is going to cost several hundred dollars because of the cost of the sand and the labor time involved.

That is money that you can spend towards the purchase of a new filter.

Installing a Sand Filter

When installing a sand filter, you should make sure before any purchase is made that you consult a swimming pool professional. A good professional will give you a recommendation on the right size sand filter for your pool.

The size of the filter is important. If the filter is not sized right, then you will continue to have problems at your pool. Your pool will not stay clear and there will always be continual issues due to the clarity of your pool water.

This also goes for when you purchase a filter that is too large for your swimming pool; It needs to be properly sized for your pool.

It may also be that a sand filter is not best for your pool. There are two other options. You need to consult a swimming pool professional, not just someone who works behind the counter at the local swimming pool store.

When a new sand filter is installed, fresh pool sand is placed in the filter. When the filter is turned on, then the sand filters the dirty pool water. The sand grains attach to any dirt and then the clean water is filtered back into the swimming pool.

This process of filtering starts as soon as the new filter is started or the sand is replaced.

The process of installing the filter and filling it with sand can be done in a few hours. And once you turn on the filter, the process starts.
