Oase AquaSkim 20 Pond Skimmer

Surface skimming equipment for removing leaves, pollen and floating pond debris

Oase AquaSkim 20 Pond Skimmer is a practical pond skimmer for pond building, filtration and maintenance work. Surface skimmers and surface intakes remove leaves, pollen, foam and floating debris before it sinks and breaks down in the pond. They are a useful addition to many koi ponds, formal ponds and larger garden ponds where surface waste collects quickly.

This skimmer product is used to remove floating debris from the water surface before it sinks. Correct positioning, suitable flow and easy basket or chamber access are important for reliable day to day use.

The important point with pond pipework is compatibility. A fitting may look simple, but the size, pipe type, pressure rating, thread, bend angle and future access all affect how well the finished system works. Choosing the correct part at this stage helps prevent leaks, reduces unnecessary restriction and makes the pond easier to service later.

This product is listed under the Oase range where applicable, but it should still be selected by connection size and application. On mixed installations, always check whether you are working with imperial pressure pipe, metric waste pipe, flexible hose, threaded fittings or rubber connectors before ordering.

Where this part is normally used

• pond surface debris removal
• koi ponds with skimmer lines
• formal ponds near trees
• filter systems that benefit from surface draw
• ponds where leaves and pollen are a regular issue

This page is written for real pond use rather than general plumbing only. Pond systems often combine gravity lines, pump-fed lines, waste outlets and service connections in one area, so it is worth planning the layout before gluing, tightening or burying anything permanently.

Choosing the correct size and connection type

Before ordering, check the outside diameter or internal hose size of the pipework you are connecting to. A 2 inch flexible hose connection is not the same thing as a 2 inch imperial pressure pipe fitting, and 110mm waste pipe is different again. If the part uses a BSP thread, check whether the connection is male or female and whether a washer, seal or thread tape is required.

On pump-fed systems, undersized pipework can reduce real flow and increase pressure on the pump. On gravity-fed systems, pipe size and smooth runs are even more important because the system relies on water level difference rather than pump pressure. Larger koi ponds, drum filters and bottom drain lines should be planned with generous pipework wherever possible.

Installation advice

Skimmers should be positioned where wind and pond circulation naturally move floating debris. Allow access for cleaning baskets, strainers or chambers and make sure the connected pipework or pump has enough flow for the model used. On koi ponds, a skimmer line is often planned alongside bottom drain circulation so surface and floor waste are both managed.

Keep future maintenance in mind. A clean installation is not just about hiding pipework; it should also allow valves to be turned, unions to be undone, strainers to be cleaned and equipment to be removed without cutting the system apart. Where a part may need regular access, avoid burying it or boxing it in permanently.

Key benefits

• Helps create a neater and more reliable pond plumbing installation
• Useful for ponds where leaves, pollen and floating debris collect on the surface
• Supports better long term maintenance when the layout is planned correctly
• Helps avoid mismatched fittings, unnecessary restriction and awkward future repairs
• Can be combined with the correct matching pipework, valves, connectors or accessories

For small fittings, it is worth checking the whole pipe run before ordering so you do not end up missing the joiner, reducer, valve or connector that makes the system serviceable. This is especially important on filter bays where access can become tight once the equipment is installed.

Advice from That Pond Guy

When we specify pond plumbing, we look at the full system rather than a single fitting on its own. Flow rate, pipe diameter, bends, valves, access space and maintenance all matter. If a pond is difficult to isolate or service, even good equipment can become frustrating to maintain. Taking a little longer to choose the correct fitting usually saves time later.

If you are unsure whether this is the correct part, compare it with the related pipework above and check the size of your existing pipe, hose or threaded connection. For new koi pond builds, filter upgrades and more complex plumbing, it is usually worth planning the complete pipe route before placing the order.
