Our Verdict

The Hayward ProSeries S166T is our top pick sand filter for above-ground pools. The 16-inch top-mount tank takes 100 lbs of number 20 silica sand per Hayward, flows a design rate of 32 GPM, and covers pools up to roughly 15,000 gallons. It uses the same proven ProSeries platform that lasts 15 to 20 years, and parts are available everywhere. You supply the pump, which is exactly why it outlasts every bundled combo.

Pros

  • 16-inch tank covers most above-ground pools up to roughly 15,000 gallons
  • Takes only 100 lbs of sand, so initial fill is cheap and manageable
  • 7-position top-mount multiport valve includes a Waste setting for vacuuming algae
  • ProSeries platform has 15 to 20 year lifespans with universally available parts

Cons

  • Filter only, so you need to pair a compatible 1 to 1.5 HP above-ground pump
  • Undersized for large 24-foot rounds and big ovals, which need the S244T instead
  • Multiport backwash routine has a learning curve for first-time sand filter owners

Why Sand Is the Right Media for Most Above-Ground Pools

Sand filtration wins on above-ground pools for two reasons: the media is cheap and the routine is minimal. A full sand charge costs 15 to 50 dollars and lasts 5 to 7 years. When the filter loads up, you turn a valve, run water to waste for 2 to 3 minutes, and you are done. There is no element to pull, hose off, and soak, which matters on a pool that lives outdoors under trees and pollen.

Sand also forgives neglect. If the pool turns green over a vacation week, you shock it, vacuum the dead algae to Waste, and backwash the rest out. A cartridge in the same situation clogs within hours and has to be cleaned repeatedly until the bloom is gone.

Cartridge still makes sense in two cases: you are on metered or well water and cannot spare 150 to 250 gallons per backwash, or you want finer filtration, since cartridge catches 10 to 15 micron particles versus 20 to 40 for sand. If you are weighing both media types side by side, our roundup of the best above-ground pool filter overall covers sand and cartridge in one list. This page ranks sand systems only.

One more scope note before the rankings. Two of the picks below bundle a pump and three are filter-only tanks. If you specifically want a matched pump and filter in one box, we compare those head to head in our best above-ground pool pump and filter combo review.

Sizing a Sand Filter by Pool Gallons

The math is simple: your filter system should turn over the entire pool volume in 6 to 8 hours of runtime. Divide pool gallons by 360 to get the minimum GPM for a 6-hour turnover.

Pool SizeApprox. GallonsMin. Flow NeededRecommended Tank
12 to 15 ft round3,400 to 5,30010 to 15 GPM12 to 14 inch
18 ft round7,60021 GPM14 to 16 inch
21 ft round10,40029 GPM16 inch
24 ft round13,60038 GPM18 to 24 inch
15 x 30 ft oval12,00033 GPM18 inch
18 x 33 ft oval and up15,300+43+ GPM22 to 24 inch

Always buy one size up from the minimum. An oversized sand filter runs at lower pressure, backwashes less often, and polishes water better. For the full sizing method, including square footage and turnover worked examples, see what size sand filter do I need.

Product Rankings

1. Hayward ProSeries S166T: Best Overall

The S166T is the small sibling of the famous S244T, and for above-ground pools it hits the sweet spot. The 16-inch top-mount tank takes 100 lbs of number 20 silica sand per Hayward, which is one bag lift-and-pour session rather than an afternoon. Design flow is 32 GPM, enough to turn over pools up to roughly 15,000 gallons inside a normal daily run, and the 7-position multiport valve gives you Filter, Backwash, Rinse, Waste, Recirculate, Winter, and Closed.

The reason to pick Hayward over a cheaper tank is the platform. ProSeries filters have been built largely unchanged for decades, so every pool store carries the O-rings, spider gaskets, and laterals. A blow-molded tank of this quality routinely runs 15 to 20 years.

Standout: longest service life on this list with the cheapest ongoing parts supply.

Honest downside: it is a filter only. You need a 1 to 1.5 HP above-ground pump such as a Hayward PowerFlo, and plumbing it with 1.5-inch fittings takes an hour of setup that a combo unit skips.

Fit: pools up to roughly 15,000 gallons. Tank and sand: 16 inch, 100 lbs. Flow: 32 GPM design rate.

2. Intex Krystal Clear SX2800: Best Pump and Filter Combo

The Intex Krystal Clear SX2800 (sold under model numbers like 26647EG) is the strongest single-box answer for Intex, Bestway, and other soft-sided pools. Pump flow is 2,800 GPH with a system flow around 2,100 GPH, or roughly 35 GPM through the sand bed, and Intex rates it for above-ground pools up to about 12,800 gallons. It connects to standard Intex hose fittings, includes a 24-hour timer, and sits directly on the ground next to the pool.

Sand load is small, about 55 lbs, though Intex specs vary by model year, so verify the quantity on your unit’s label before buying bags. Our guide on how much sand for an Intex sand filter breaks down the exact fill for every Intex model, including the larger SX3000.

Standout: genuinely adequate flow in a plug-and-play package, which almost no bundled kit filter can claim.

Honest downside: the integrated pump is the weak point. Expect 3 to 6 seasons rather than the 15-plus years of a standalone Hayward tank, and when the pump dies you replace the whole unit.

Fit: pools up to about 12,800 gallons. Tank and sand: compact tank, about 55 lbs (verify label). Flow: 2,800 GPH pump, roughly 2,100 GPH system.

3. Rx Clear Radiant: Best Complete System Value

The Rx Clear Radiant line pairs a molded sand tank with a matched above-ground pump on a single base, sold in 16 to 24 inch tank sizes with 1 or 1.5 HP pump options. The 16-inch version takes around 100 lbs of sand and suits pools to roughly 15,000 gallons, while the 22 and 24 inch versions cover big ovals. Confirm the sand weight against the label for your exact tank size.

Radiant systems cost noticeably less than buying a Hayward tank and pump separately, and unlike the Intex combo, the pump and filter are separate components, so a failed pump can be swapped without discarding the tank.

Standout: standalone-style hardware at combo pricing, with a replaceable pump.

Honest downside: Rx Clear is a smaller brand, so spare valve parts usually mean ordering online rather than walking into a pool store, and the bundled pumps are louder than premium Hayward or Pentair units.

Fit: roughly 8,000 to 20,000+ gallons depending on tank size. Tank and sand: 16 to 24 inch, about 100 to 250 lbs by size (verify label). Flow: roughly 30 to 50 GPM by configuration.

4. XtremepowerUS Sand Filter System: Best Budget

XtremepowerUS sells 13 and 16 inch sand filter systems with a bundled 0.75 HP pump, usually at the lowest complete-system price you will find. The 13-inch tank takes roughly 45 lbs of sand and the 16-inch around 100 lbs, with flow in the 2,400 GPH range depending on configuration. Check the listing and tank label for your exact model, since specs shift between production runs.

For a 12 to 18 foot round pool on a tight budget, it does the job: real sand filtration, a working multiport valve, and a pump, often for less than a Hayward tank alone.

Standout: price. Nothing else delivers a full sand filter system this cheap.

Honest downside: fit and finish. Owners report weeping unions, thin tank walls, and a pump that is loud and short-lived compared to name brands. Thread-seal the fittings during assembly and treat it as a 3 to 5 season purchase, not a decade one.

Fit: pools up to roughly 10,000 gallons. Tank and sand: 13 or 16 inch, about 45 to 100 lbs (verify label). Flow: around 2,400 GPH.

5. Hayward ProSeries S244T: Best for Large Above-Ground Pools

For 24-foot rounds and 18 x 33 or larger ovals, the 24-inch S244T is the answer. It holds 200 lbs of number 20 silica sand, flows 48 GPM, and is rated for pools up to 24,000 gallons, which is more capacity than any above-ground pool needs. That headroom means low operating pressure and long stretches between backwashes. It also took the top spot in our all-types above-ground filter roundup, where we cover its pump pairings in detail.

Standout: never undersized. It handles pollen season, heavy bather loads, and algae recovery without pressure spikes.

Honest downside: overkill for pools under about 13,000 gallons, and the 200 lb sand fill plus separate pump purchase makes it the most expensive setup here.

Fit: pools up to 24,000 gallons. Tank and sand: 24 inch, 200 lbs. Flow: 48 GPM.

What Sand to Buy

Every filter on this list runs on number 20 silica sand, graded 0.45 to 0.55 mm. Play sand and paver sand are the wrong grade and will pass straight through the laterals into your pool. Alternatives like glass media and zeolite work in these tanks too, with finer filtration and lighter fills. We compare brands and media types in our best pool filter sand review.

Setup Outline

The install is the same across brands, with minor variations for combo units:

  1. Set the tank on a level pad of pavers or compacted gravel, close to the pool but outside splash range.
  2. Fill the empty tank about halfway with water to cushion the laterals, then pour sand in slowly to the labeled weight.
  3. Rinse spilled sand off the valve threads, install the multiport valve, and connect the pump and hoses.
  4. Backwash for 2 to 3 minutes before ever filtering, then Rinse for 30 seconds. This flushes sand dust that would otherwise cloud the pool.
  5. Turn to Filter, note the clean starting pressure, and backwash again whenever pressure rises 8 to 10 PSI above that baseline.

Step 4 and the ongoing routine trip up more new owners than anything else. If you run an Intex unit, the valve labels differ slightly from standard multiports, so follow our walkthrough on how to backwash an Intex sand filter the first time through.

Frequently Asked Questions

What is the best sand filter for an above ground pool?
The Hayward ProSeries S166T is the best sand filter for most above-ground pools. The 16-inch tank takes 100 lbs of sand, flows 32 GPM, and handles pools up to roughly 15,000 gallons, which covers the majority of round above-ground pools. For pools larger than about 15,000 gallons, step up to the 24-inch Hayward S244T. If you want a pump included in the box, the Intex Krystal Clear SX2800 is the best combo unit.
How much sand does an above-ground pool sand filter need?
It depends on tank diameter. The 16-inch Hayward S166T takes 100 lbs per Hayward, the 18-inch S180T takes 150 lbs, and the 24-inch S244T takes 200 lbs. Intex combo units take much less, around 55 lbs for the SX2800. Always confirm the exact quantity on your tank label or manual before buying, because overfilling causes sand to blow back into the pool.
Can I use a sand filter with an Intex or Bestway pool?
Yes. Intex sells its own Krystal Clear sand filter pumps that connect to Intex hose fittings directly, and they also work on Bestway pools with the right hose adapters. A standalone filter like the Hayward S166T can also run an Intex pool, but you will need 1.5-inch plumbing adapters and a separate pump, so most soft-sided pool owners are better served by the Intex combo.
How long should an above-ground pool sand filter run each day?
Long enough to turn over the full pool volume at least once every 24 hours. Divide your pool gallons by the system flow rate in gallons per minute, then divide by 60. A 10,000-gallon pool on a 32 GPM filter needs just over 5 hours. In peak summer or during algae treatment, aim for two turnovers per day.
Why is sand blowing back into my above-ground pool?
The usual causes are the wrong sand grade, an overfilled tank, or a cracked lateral at the bottom of the tank. Use number 20 silica sand only, fill to the exact weight on the tank label, and if sand keeps appearing after a fresh fill, open the tank and inspect the laterals for hairline cracks. A brief puff of sand right after backwashing is normal.
