Everyone who owns a pool knows how important it is to keep it clean and in good condition. An integral aspect of any swimming pool system, a pool filter aids in the removal of dirt, debris, and other impurities from the pool water. The media a pool filter uses to collect debris as water passes through it is an essential feature of the device.
The low cost and great effectiveness of sand as a particle filter make it a common media choice for pool filters. Picking the right sand for your pool filter can be a challenge, though, because there are so many varieties on the market.
What is pool filter sand?
Sand ideal for use in pool filters is known as pool filter sand. Pure, unprocessed silica sand that has undergone washing and screening to remove contaminants is its raw material. The final product is excellent sand suitable for use in both in-ground and above-ground pools.
Types of Filter Sand
As a side note, you should never filter your pool water with sand-pit or regular construction sand. These are the three options available to you.
- Glass filter sand
This pool filter sand, naturally composed of crushed recycled glass, traps particles as small as microns. If you’re dealing with an algae issue, this pool filter sand is ideal.
Despite its negative environmental effects, silica sand remains the only viable choice. You have the option to invest in glass sand if you are ready to pay a bit more money. The use of recycled glass in its construction reduces its negative effect on the environment.
- Zeolite filter sand
There is very little that can flow through this pool filter sand, which originates from pure volcanic rock. What’s more, zeolite is the only material that can help keep pool water chlorine-balanced. Renewing and reusing it lessens red, stinging eyes. It goes by the name Clinobrite and has an impressive 10-micron filtering capacity.
- Silicone Quartz Sand (Silica Sand)
Commonly referred to as “silica pool filter sand,” this naturally occurring product is made from broken quartz. Its filtration capability registers at 20 microns, yet it is presently the most common and inexpensive filter sand.
What to Look for in Pool Filter Sand
A few important factors need consideration when selecting pool filter sand. Among them are:
- Purity
After washing and screening, look for pool filter sand that is free of contaminants. Finer sand is preferable for filtering out impurities.
- Amount Required
The amount of sand your filter needs is directly proportional to the pool’s dimensions and the filter’s specific model. Measure well to be sure you have enough sand.
- Compatibility
Pool filter sands may not work with certain models. Contact the maker of your filter to be sure the sand you buy is compatible with it.
- Grain Size:
The type of filter you have will determine the appropriate grain size for the sand used in the filter. Typically, you want a grain size of 0.45 to 0.55 millimeters.
The advantages of using pool filter sand
Using pool filter sand instead of other filter media has many advantages. Listed below are a handful:
- Efficient Filtration:
Sand used in pool filtration systems is excellent at removing dirt and other pollutants from pool water.
- User-friendly:
The sand used in these filters is simple to maintain and replace. Empty the existing sand and replace it with fresh.
- Affordable:
Pool filter sand is typically more affordable than other filter media, such as diatomaceous earth or cartridge filters.
- Longevity:
In certain instances, the sand can last as long as five years. In the long term, that translates to less upkeep and lower expenses.
How often do you need to change the sand in a pool filter?
The standard recommendation is to replace the filter sand in your pool every 5 years. This time period can vary, though, based on factors like how often you backwash the pool and how frequently you use the pool overall.
A poorly balanced and maintained pool will put extra strain on the sand filter, requiring more frequent sand medium changes.
With proper maintenance, chemical balance, and infrequent use, pool filter sand can last up to seven years.
Signs that it’s time to replace the sand filter
The sand filter in your pool may require replacement if you observe any of these symptoms.
- Unusual Algae Growth:
The sand filter may not function properly if algae grow in areas where it normally doesn’t.
- Poor Water Quality:
A slightly greenish or cloudy hue to your pool water could indicate that your pool filter sand isn’t doing its job properly.
- Noisy Filter:
Debris and sand buildup inside the sand filter could be the cause of any unusual noises it has been producing.
- Leakage:
You may need to replace the sand filter if you find that water or sand is leaking out from around it.
- High Water Pressure:
A pressure reading that is much higher than normal on your pressure gauge could mean that the sand filter needs replacement or cleaning.
Is a bigger pool sand filter better?
Your pool filter can impact the efficiency of your pool sanitation system and how clean your pool is. You need a pool pump to run water through any filter to clean pool water. The system is the set-up that includes the pump and the filter. A pool’s water stays debris-free and clean thanks to filters that gather tiny particles like hair, dirt, dust, oils, and more. The bigger the filter, the less often you’ll have to clean it, and the better job it will do.
Is it better to use a DE pool filter or a sand filter?
The response to this question will vary. The filtering system you choose will depend on your specific needs. If your pool water isn’t already somewhat murky or green, though, a sand filter might be all you need. To use and keep up with, it’s dead simple. A DE filter is the way to go if pollen is a major problem in your pool. It’s becoming more common in some regions and quickly causes the water to turn green. This filter is unique in removing pollen from water while also purifying it. It accomplishes this goal without resorting to a cocktail of chemicals.
Tips to keep your pool filter sand in use for a longer period
For the sand filter to last longer, it’s recommended to backwash it once a month. This will aid in removing the particles that become stuck in the filter and hasten their wear and tear. Consider these additional suggestions if you want your sand pool filter to last as long as possible.
Clean your skimmer
You need to clean the skimmers’ filters regularly to keep them clear of debris. Clogged filters diminish filtering efficiency.
Make your sand filter work efficiently
You can extend the life of your sand filter by running it daily at a slow but steady pace. Depending on the pool and the type of filter, the ideal operating time for a pool filter is eight to 10 hours.
Checking your sand filter regularly
Flattened pleats, tears, and fraying are indications of deterioration that need inspection on a regular basis in the filter. Quick detection allows you to head off any issues before they escalate. You can clean or change the filter to make it last longer.
Conclusion
There are many different kinds of pool filter sand, and they all have advantages and disadvantages. By considering what you need, what your pool requires, and how much money you have to spend, you may discover a product that works for you and your pool. Whether you prefer natural alternatives to typical pool filter sand or vice versa, what matters most is selecting a product that works well with your filter and offers durable filtration efficiency.
