Pool Filter Sand Guide

To keep your water pure, it can be important to buy the best pool filter sand available. It can come in different forms and when you buy a quality product, it can help the sand filter work smoothly, ensuring clean water for you to enjoy. When you get this right, it traps the unwanted debris so it doesn’t make its way into your pool but some are better for filtering tiny particles than others.

This is why we have created the following buyer’s guide. By the end of it, you’ll know how to make a smart decision.

What To Look For In Pool Filter Sand

Size

The size fo the pool filter sand will determine how effective it is. Look for a product that is 0.45 – 0.55 mm. This will ensure it can hold onto the finer debris and anything too big will mean too many particles are escaping and finding their way through. 

Jagged Edges

Most sand in this variety should be known for its jagged edges, but they should also stay that way for longer. When they start to smooth, they cannot keep hold of the small particles that are supposed to. 

Over time, this will naturally happen but you should get 3 years as a minimum before you need to consider changing the sand.

Non-Toxic Formula

Although you aren’t going to get this with natural sand, some alternatives are often used instead. Even if it is made from crystalline silica, it still needs to be safe from contaminating your water. 

Multi-Purpose

Although it sounds obvious, most brands are fine to use for above ground sand filters and in-ground pool filters. Both filter types need sand to be effective and although they cannot tell the difference, differences like the flow rate and tank size mean you need to check the sand is right for your filter.

Some brands can also be used in a fish tank since it is clean and appropriately sized. This is useful since it means you can use the leftover sand and not leave it for 5 years although you should check that it is fine to add to a fish tank first.

Benefits Of Using a Sand Filter

One of the main reasons a lot of people use a sand filter is that they are easy. Maintenance is low when they are up and running so you don’t have to be an experienced pool cleaner to get to grips with them.

The sand doesn’t need to be changed often so when you have the right level you don’t have to touch it for years. This makes it an affordable way of keeping the pool water clean.

Another benefit is that they are good at their job of keeping small particles out of the water. No one wants a dirty pool and a sand filter is one of the most effective methods of keeping it clean.

How Long Does Sand Filter Sand Last?

When you have added it, pool filter sand lasts around 3 – 5 years. Several factors can make it last longer, most notably how frequently you have your filter running. 

If it is constantly on, then you might find that you. need to change to pool filter sand sooner. It loses its effectiveness when the edges of the sand become smooth instead of jagged which is how it manages to trap tiny particles.

How Much Pool Filter Sand Do I Need?

This depends on the size of the filter and the pool. Also, the model you have will determine the amount of sand you should use. It is usually easy to find out which is best as the manufacturer’s manual will tell you how much is ideal to keep the water clean.

Ideally, there will be a minimum of 6 inches between the top of the sand and the roof of the filter but again, it is best to consult the manual before filling it up. 

Can You Put Too Much Sand In A Sand Filter?

You can, water should have plenty of space to flow through the sand or it won’t be able to do its job. This is where you will find your rinse cycles to not be as effective and the water will not be as clean as you might expect.

What Is Pool Filter Sand?

Basically, it’s sand! However, there is a difference. Pool filter sand has been carefully selected to ensure it traps ultra-fine debris and stops it from entering the pool. 

It is pricer than your regular sand-box brands which can make it tempting to go cheaper and use, pool filter sand is a lot finer for a reason and you cannot switch to another type.

Traveling through the filter, pool water flows through sand, and because they are so fine, it traps small particles and is filtered out. A regular sand particle is larger and will not trap the tiny particles as small as 20 microns sometimes.

Does Pool Filter Sand Remove Algae?

Yes, the good news is that algae will be trapped by the sand when you buy a product that can block particles of around 20 microns. This is because algae tend to be approximately 30 microns. 

Still, this doesn’t mean that algae spores cannot find their way into your pool water if you aren’t on top of the chemical levels. Even a small amount can spread fast which is why it is important to stay on top of the maintenance of your pool. 

Why Do People Use Sand Filters?

One of the main reasons they are so popular is because they are affordable. There are fancier models available that use different methods but are more expensive. 

A sand filter is low maintenance yet effective way of keeping minute particulars out of your pool water on a budget.

Can I Use Normal Sand In A Pool Sand Filter?

In short, no! Because pool filter sand is finer, it will trap the small particles. This is something that larger sand will not be able to do and you could even end up damaging the filtration system when using the wrong product.
