A: In accordance with the instructions, S220T requires 250 lbs. of sand specifically manufactured for sand filters. This is usually available at your local pool supply store.
Sand Required: 250lbs

Best of all, the Pro`s full-flow technology reduces your energy costs because the filter operates for shorter periods. The Seven-position valve puts you in control.

The professionals that recommend changing your pool filter sand argue that not only should you replace your sand every 3-5 years, but you should also clean it in the interim. The argument for changing the sand is based on the belief that sand does eventually wear down and become smooth.
Sand filters will often be able to perform for around three-to-seven years, depending on use. If you frequently clean and backwash your filter and only use the pool seasonally, you can expect to replace it after at least five years.
Sand filters have a lower filtering ability than both DE and cartridge filters. Sand filters only remove dirt and debris down to 20-40 microns, allowing smaller particles to pass into the pool water. They`re the least energy-efficient option.
It should take about 1 hour to get 12-18 litres of filtered drinking water. Pathogens and suspended solids are removed through biological and physical processes that take place in the sand.
To calculate the diameter of fiberglass filter sand: For every 0.93 square meters (10 square feet) of filter sand surface, we consider a flow rate of 15 to 20 gallons (60 to 75 liters) per minute. Also, the height of the sand filter is 1.2 times the diameter of the same filter.
Every pool should cycle through all of its water at least once a day, so most pool owners will want to run their pumps for at least 4-8 hours daily.
The rule of thumb is generally 8 hours, although it could be anywhere from 6-12 hours, depending on your pool`s size. Each pool is unique, so to keep your pool pump efficient and effective, you need to figure out exactly what your pool`s turnover rate is.
Be sure to replace the filter media at least every three to four weeks and give the filter housing a quick rinse. If any algae or debris has accumulated in the intake tube, clean that as well.
Conclusion. Fish tank filters and motors are the most important equipment in the fish tank to keep the water clean and fresh. Your filter needs to be on 24×7 to filter and keep an oxygenated air flow.
Aquariums generally take four to eight weeks to cycle. Factors such as the size of the tank and the water`s pH and temperature can affect how long cycling takes. To prevent the cycling process from taking longer than necessary, closely monitor the temperature and pH of your aquarium`s water.
Sand filters should be cleaned at least once per season, preferably in the fall before closing. You must clean your sand filter after encountering bouts of algae.
After the hose fills with water, backwash your sand filter for 2 – 3 minutes or until water runs clear. Shut off pump motor and push T-handle back down into locked position. Turn pump back on and note lower pressure.
The recommended minimum filter surface area is 2.50 cubic feet per minute (cfm) per square inch of filter area. Example 1: 2000 cfm ÷ 250 inches = 800 square inches or 20″ X 40″ filter grill. The maximum allowable filter velocity is 300 feet per minute (fpm) on disposable filters.
It`s essential to make sure your filter works for your pool size. If you buy a filter too small, it just won`t do the job, and you`ll be swimming with bacteria. Buy a filter too big and you`ll waste money on your energy bill every month.
What is the volume of 1 tonne of sand? A tonne of sand is approximately 0.624 m³ or 22.045 ft³. If you divide the mass of sand by its density, you obtain the volume that the amount of sand occupies. In this case, 1000 kg / 1601.95 kg/m³ = 0.624 m³ .
Sand Filters sizes range typically from 1 bag to 5 bag, each bag weighing 40kg.
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.

Some commercial properties require 24-hour a day pump circulation, but as a homeowner, this is not advisable. If you are lucky enough to own an Energy Efficient, Variable Speed swimming pool pump (VSP) then, yes, technically you could run your pump for 24 hours a day.

Keeping your pump and filter system running for at least 8 to 12 hours is the best way to keep your pool safe and clean. Also, keep track of your water level and make sure it is halfway up the opening of your water skimmer.
About every seven years, you should change the sand in the filter. If you`re not using chlorine, you should do it more often, about every three to five years. Chemical cleaning of the sand should take place about once a year usually or twice a year if you use a biguanide sanitizer.
The water must be circulating so the chemicals get distributed throughout the water. You can — and should — add pool shock at night, though. The sun can burn shock off during the hot daytime hours, but you still need to have the pump running to circulate the water.
As mentioned above, it`s okay to run your pool pump whenever it works for you, so long as it is running long enough to turnover at least once during a 24-hour period. So yes, it is okay to turn off your pool at night, but there are several reasons you might not want to in order to make the most of this time.
