The ProPools Picks

Best Overall Fit for Most Above Ground Pools

CaliMar 19" Sand Filter System + 1 HP Pump (5-1776-002 | 57844)

View this Item

• Why it earned the spot: A practical “sweet spot” size for many above-ground pools, with standard 1.5" connections and included hoses.
• Best for: Owners who want proven sand filtration with straightforward maintenance.
• Consider before you buy: Sand filters require occasional backwashing, which uses some water. Confirm your pool uses common 1.5" hose connections.

Best for Bigger Pools / Faster Recovery After Heavy Use

CaliMar 23" Sand Filter System + 1-1/2 HP Pump (5-1787-002 | 57845)

View this item

• Why it earned the spot: Larger tank and higher sand capacity for longer intervals between cleanings and stronger performance under heavy bather load.
• Best for: Larger round/oval pools, frequent parties, high debris areas, or quicker clearing after storms.
• Consider before you buy: Bigger systems can mean more backwash water per cleaning—plan your water-level management.

Best Upgrade: Energy Savings + App Control

Doughboy (HII) ESPA-SilenPlus Variable Speed Pump + Sand Filter Combo (Bluetooth)

Choose your size:16" Combo|19" Combo|23" Combo

• Why it earned the spot: Variable speed control and built-in Bluetooth for app-based pump control.
• Best for: Owners who want more control, quieter operation, and the flexibility to run longer at lower speeds.
• Consider before you buy: Variable-speed performance is best when you’re comfortable running the pool more hours/day at lower RPM.

Best Budget / Smaller Pool Fit

CaliMar 13" Sand Filter System + 3/4 HP Pump (5-1735-002 | 62371)

View this item

• Why it earned the spot: A cost-contained entry into a CaliMar sand system with standard above-ground hookup approach.
• Best for: Smaller pools and lighter bather loads.
• Consider before you buy: For larger pools, a 19" system is often a better long-run fit for fewer cleanings.

Mini Buyer’s Guide: How to Choose the Right System

1) Size it by “turnover”

• A practical goal is to size circulation so the pool can filter roughly every 6–8 hours. Bigger pools need more flow (or longer run time).

2) Choose the filter style that matches your maintenance preference

• Sand: Common, durable, and easy to maintain via backwashing.
• Cartridge: Often clearer water with no backwashing, but you’ll clean cartridges periodically.
• D.E.: Highest clarity potential, with more hands-on maintenance.

3) Avoid a common mismatch

• Don’t pair a very strong pump with an undersized filter tank. It can raise pressure and increase cleaning frequency.
