Filter pumps and pool protection at entry price
Two of the four items here are filtration and two are protection, which is a reasonable summary of what an above-ground pool actually needs beyond the pool itself.
The sand system’s timer is worth singling out. A timer decides how many hours a day the water turns over, and turnover — not peak flow — is what keeps a pool clear. A high hourly figure on a unit that runs two hours a day does less than a modest one running eight.
The underlay and the cover are dimension products. The underlay is quoted at its own size rather than the pool’s, and those differ by the margin you need under the rim. The reviews state which measurement each page is giving.
13 200 l/h, 12 m head, 30 kg tank, 1–24 h timer
The largest system here: 13 200 l/h against 12 m of head, a tank taking up to 30 kg of sand, a timer adjustable from one to twenty-four hours, and self-priming operation.
Best for: A 40 000-litre pool where the system is expected to run on a schedule and be left alone
