It is not advisable to use play sand in your pool filter. The larger particle size and different chemical compositions of play sand mean that much of the dirt and debris in your pool water will just pass through the filter. It just isn't very effective at cleaning your pool water.
The Bottom Line
It's a bad idea to use anything in your pool filter except sand specifically processed and sold for that purpose. Play sand simply won't keep your pool as clean as it should be.
Silica pool filter sand is the most commonly used type. It's inexpensive, easy to find, and can filter particles down to 20 microns, which is approximately 0.0008 inches. Silica sand is made with ground quartz, and it has rough edges to help trap particulates.
The most obvious difference when you compare these types of sand is the size of the grains. Pool filter sand has a much smaller particle size. They are no more than half a millimeter in diameter. This small size allows them to trap even very fine matter.
Masonry sand or Play sand won't work in a pool filter, use only a high quality Pool Filter Sand. Pool Filter Sand, is specifically graded silicone quartz, . 45-. 55 mm in size, otherwise known commercially as #20 silica sand.
QUIKRETE® Filter Sand is used for swimming pool filtration systems designed for use with silica sand.
Pour sand carefully into the pool sand filter until laterals are fully covered. For this unit 3 bags should leave at least 6" space between the top of the sand and the top of the filter. Level sand as you pour and make sure the center pipe remains centered in the opening.
Too much sand and your filter will likely not run correctly or may break when reassembling. Too little sand and you will have cloudy water no matter how much your filter runs. For this reason check your filter manufacturer's specs.
The best way to remove the sand is to either use a portable wet/dry vacuum or just scoop it out with a small can. Once the old sand has been removed, hose out the inside of the tank to clean the filter out. Once this water is drained, replace the drain cap and fill the tank 2/3 full of water.
This product is capable of really keeping a person's swimming pool nice and clean. It comes in 50-pound bags that are easy to pour and easy to use, and they are always ready for use. This filter media does a fantastic job of filtering dead organic components and other forms of sediment out of swimming pool water.
The most common media used is sand filtration. The recommended type is No. 20 grade silica sand, with specification of 0.45 to 0.85mm (0.018 to 0.033 inches) with a Uniformity Coefficient less than 1.75. Too fine of a grade of sand will clog too quickly, and too soft of a sand will break up and also cause clogging.
You need chemicals with a sand filter because they require sanitization, phosphate removal, pH adjustments, and alkalinity alterations.
Question: Is sand supplied in the filter when it is delivered? Answer: The sand does not come with the pump.
The most commonly used pool filter sand is #20 silica sand. It comes from ground quartz, which creates sharp silica grains with jagged edges excellent for trapping particulates from passing water.
Changing the pool filter sand is a bit of a pain, especially in the back region, but a bag of pool filter sand costs around R90 at your local Builders Warehouse, and you should only need two bags for most pool filters.
If you see it blowing out into the pool, something is broken. The most common problem is a cracked lateral, which is one of the perforated pipes at the bottom of the filter that catches water that has circulated through the sand.
As pool filter sand is considered a hazardous material, you should not simply throw the sand away in your trash can. To properly dispose of the sand, you need to call a disposal expert or take it to a disposal site.
Replacement sand for your sand filter typically costs around $25 per 50-pound bag, and your filter may require 100 to 600 pounds or more depending on the size and model. More than likely, you'll need about 350 pounds of sand for an average-sized inground pool filter.
The filter flow rate must be rated at least the same GPM as your pump, or higher. With pool filters, it's best to err on the larger size so it can handle the power of your pump. A helpful rule of thumb is to choose a filter with at least 1 square foot per 10,000 gallons pool capacity.
How Often Should You Backwash a Pool Sand Filter? As a general rule of thumb, you should backwash and rinse your filter about once a fortnight. The optimal time is right after you vacuum the pool. However, if your pool has had a lot more use than normal, it may be necessary to backwash once a week.
Answer: Get as much of the debris and algae as you can out manualy (net, vacuum). You can also vacuum the sand, but make sure you vacuum to waste so it does not damage your pump/filter again.
This pump has a flow rate of 3,000 gallons per hour, creating a system flow rate of 2,450 gallons per hour and making it a perfect fit for any size Intex above ground pool.
