A tank, a media bed, and a valve with six or seven positions · review
A 400 W system publishing both flow and head, with a 25-litre tank, IPX5 protection, a 1.9 m mains lead, and an operating note telling you to fill the whole circuit before switching on.
The bottom line A solid middle of the shelf with one unusually good habit: it tells you how to start it. Flow with head, IPX5, a weatherproof housing and a stated cable length make it readable, and 8.5 metres of lift is what decides whether a system can sit where you want it. The unpublished media charge is the row that matters most on a filter that arrives empty.
A sand filter system delivering up to 10 200 l/h with a maximum lift of 8.5 m, from a 400 W pump, for pools up to 35 000 litres. The tank holds 25 litres and is stated suitable for all filter media including filter balls. The housing and lines are a robust plastic described as weatherproof, rated IPX5, with a 1.9 m mains lead and a pressure display.
The listing carries an operating note: fill the entire system with water — including the filter tank and all hoses — before switching on, so the water circuit is complete.
Fill the entire system with water before switching on.
It belongs in a manual and it is printed in the listing, which is where somebody about to buy will actually read it.
A pump run dry is a pump damaged, and a sand system has a tank and several metres of hose that all have to be full before anything primes. It is the commonest first-day mistake on this shelf.
10 200 l/h against 8.5 m.
The lift figure is what decides siting: a system that has to raise water three metres from a sunken pool to a terrace is working against three of its eight and a half before any hose or medium is counted.
Three systems in this family publish both figures. This is one.
The media charge. A 25-litre tank is a volume; a sand purchase is a weight, and the conversion depends on the medium.
Bestway, in the same family, publishes 36 kg at grain #20 for a 38.5 cm tank. This listing publishes a tank volume and leaves the sack to be worked out — and the page leaves the row empty rather than working it out on the maker’s behalf.
The German, French, Italian and Spanish Amazon stores sat between 156 € and 170 € at the single check this page is built on.
The British Amazon catalogue holds the reference with no seller standing behind it.
The American Amazon store gave back nothing, so the buy button there lands on a search instead of a blank page.

Because a pump run dry damages itself, and a sand system has a tank and hoses that have to be full before the circuit will prime. Publishing that in the sales copy rather than only in the manual is a small act of honesty, and it is the sort of instruction that gets skipped.
Protection against water jets. The X means dust ingress was not rated. For a pump standing in a garden it is the relevant digit, and three systems in this family publish it where the rest publish nothing.
Not published. Twenty-five litres is a volume and a sand charge is a weight, and the two do not convert without knowing the medium. The page leaves the row empty rather than converting one into the other.
A 35 000-litre pool where the head figure decides whether the siting works

10 200 l/h, 400 W, 20 l tank, 60–65 dB(A)/m
The only filter system on this shelf that publishes a noise level with a distance — 60 to 65 dB(A) at one metre — alongside 10 200 l/h from a 400 W pump and 800 g of filter balls.
Best for: A system sited near a terrace, where the decibel figure is the deciding one
6 056 l/h pump, 4 920 l/h through-flow, 38.5 cm tank, 36 kg sand
The listing that states its media requirement in full — 36 kg of #20 quartz sand or 1 000 g of filter balls, neither included — alongside two flow figures, a 38.5 cm tank and both hoses in the box.
Best for: A first sand system, where knowing exactly what else to order is worth more than a headline flow
9 000 l/h, 7.5 m head, 250 W, 7-way, 32/38 adapter
A 250 W system publishing both ends of its curve — 9 000 l/h and a maximum head of 7.5 m — with a seven-position valve, a pressure gauge, IPX5 and adapters for both hose sizes.
Best for: A mid-sized pool where knowing the head before ordering matters
