What is a high rate sand filter?
A high-rate sand filter that’s backwashed regularly can go many years without needing fresh sand. High-rate sand filters clean water via a process known as depth filtration, meaning that dirt penetrates the sand bed and is captured in the tiny spaces between grains of sand.
Which pool sand filter is best?

When should you backwash high rate sand filters?
A good rule of thumb is to backwash once the pressure displayed on your pressure gauge is 8-10 psi over the starting level. Most pressure gauges on sand filters have a red and green zone. When the needle is close to or within the red zone, it’s a good time to backwash.
How long should pool sand filters last?
When do I need to replace my sand? On average, sand should be replaced every 3-5 years. This may be longer if the pool stays clear, or shorter, if the filter runs all the time. The jagged edges of the sand wear down and become smooth as the sand ages.
What PSI should my pool sand filter run at?
Your filter may be clean and normal at 9-10 psi, but your neighbor’s filter gauge could run higher, and be clean at 15-16 psi. Some systems with very low resistance can run very low pressures, barely registering, while other filter systems can run quite high, pushing 30 psi when the filter becomes dirty.

What size pool filter do I need for a 20000 gallon pool?
Typical D.E. Filter sizes are 36 sq ft, 48 sq ft, 60 sq ft, and 72 sq ft (they also make a 100 sq ft Quad D.E. Filter). So you can easily get away with using a 48 sq ft D.E. Filter on a 20,000-gallon pool.
What PSI should my pool be at?
The pool filter pressure should be steady, operating in a range of +/- 10 psi. When it’s outside this range, very low or very high, then you know that something’s wrong. Some gauges allow you to set the clean and dirty range, or you can write it on the filter tank with a marker.

How often should you backwash a sand filter?
“How often should I backwash my sand filter”? Ensure you do it if there’s an algae outbreak or after a significant storm. A DE( diatomaceous earth)filter system needs cleaning six or more times each year. If you have a sand filter, backwash it every month and tear it down twice every year.
What PSI should pool sand filter be at?
How high should the sand be in a sand filter?
Most sand filters are designed to be filled about two-thirds of the way. This allows for a bit of space above the sandbed, but still catches all of the water flowing through it. This is a good basic rule to follow, but it is still good to know exactly how many pounds of sand your sand filter requires.
Can a pool filter be too big?
Selecting a small one for a large pool will require frequent filter replacements and might even break down under pressure, while the one that is too big will work too quickly and powerfully, and might make the pool unsafe. Therefore, it is essential to size the filter properly.
What size sand filter do I need for a 30000 gallon inground pool?
So for a 15,000-gallon pool, I suggest a 300 sq ft filter, for a 20,000-gallon pool a 400 sq ft filter and for a 30,000-gallon pool a 500 sq ft filter. You can use a smaller filter if you choose, just note that you will be cleaning it often and the water flow may not be as efficient as going with a larger filter.
Can a filter be too big for a pool?
Is sand filter better than cartridge?
If you are looking for a highly efficient solution with the least amount of bacteria and debris left swimming around in your pool, the cartridge filter is your best solution. The cartridge filter can catch finer debris than a sand filter, being 10-20 microns versus 20-40 microns.

What happens if you put too much sand in a sand filter?
Adding too much sand to your pool filter can cause the pressure in your filter tank to rise and negatively affect the performance of the sand filter. If there is too much sand in the filter, it may cause certain components to break when putting the filter back together.
What PSI should my sand filter run at?
9-10 psi
Your filter may be clean and normal at 9-10 psi, but your neighbor’s filter gauge could run higher, and be clean at 15-16 psi. Some systems with very low resistance can run very low pressures, barely registering, while other filter systems can run quite high, pushing 30 psi when the filter becomes dirty.
What pressure should you backwash a pool?
