Quite as, how do I determine the size of my pool filter?
Filter Size to Pool Size The formula is Length x Width x Average Depth x 7.5, for rectangular pools. For oval pools, change the multiplier from 7.5 to 5.9.
However that may be, how big of pump do I need for a above ground pool? For round above ground pools up to 24 ft. ( pools with less than 15,300 gallons) use a 1 HP pump. For round above ground pools over 24 ft. (pools with more than 15.300 gallons) use a 1.5 HP pump.
Futhermore, what size pool filter do I need for a 20 000 gallon pool?
A 20,000 gallon pool would use a 300 sf cartridge filter.
How much is a sand filter for an above ground pool?
Inground pool sand filter prices range between about $450 to over $1,200, depending on the size. Above ground pool sand filters are often cheaper at starting costs in the $300 to $500 range.
So, when considering some of the more popular sizes of above ground pools, a 24-foot round pool has roughly 13,593 gallons of water and a 15 x 30-foot oval pool has about 10,000 gallons. This means for a 24-foot round pool, you need a pump that circulates 27,186 gallons per day.
Oversizing a swimming pools filter is unlikely to cause problems but having a huge pump and a small filter can result in accelerated wear and tear. A larger filter with a smaller pump reduces the work the pump must do to keep the swimming pool's water clean.
Calculations. Multiply the diameter by the diameter by the depth by the water by the number 5.9 to determine the volume. For a 15-foot round pool that is 4 feet deep, the fomula would look like this: 15 x 15 x 4 x 5.9 = 5,310 gallons of water.
The difference between the A/C and B filter is the height. The B filter is nominally 10" high and the A/C is 8" high. The B filter is meant for 2500 GPH pumps. ... The B filter is meant for 2500 GPH pumps.
Cartridge Filter Cartridge filters can screen out twice as much dirt and debris as a sand filter. Its larger filtration area allows the water to progress through the cartridge removing smaller particles. Maintenance is much easier in that there is no need for a back-washing step.
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.
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.
Pool owners often mistakenly believe if they choose a 2 HP pump over a 1 HP pump, they are getting double the performance. This is simply not true. ... For instance, a pool with water features (deck jets, waterfall, etc) tied into the main pool pump might require a higher horsepower to provide enough flow.
No. The reason being is that there is no true “minimum flow rate” of a filter. The tank may take longer to fill up if we have a ½ HP pump on a 800 pound commercial sand tank but the filter will still scrub the water to the same standard.
