How AquaMesh / Matala supports filtration

Interconnected fibers form a three-dimensional mat through which water can pass. The structure intercepts debris and provides surfaces for microbial colonization. Lifegard describes the material as being formed from thermo-polypropylene or thermo-polyethylene compounds.

Mechanical filtration collects suspended solids. Biological filtration depends on established microorganisms, adequate oxygen, water conditions, and suitable flow. Adding a new mat does not immediately establish a mature biological filter.

The four AquaMesh / Matala filtration densities

The color sequence below shows a suggested progressive arrangement, following the direction of water flow from the most open grade to the densest. Choose the stages your filter design and debris load require.

1. 1. BlackExtra low densityCoarse stage
2. 2. GreenMedium densityIntermediate stage
3. 3. BlueHigh densityFiner stage
4. 4. GreyExtra high densityDensest stage

Stage 1: Black — coarse mechanical filtration

Black is the most open, extra-low-density grade. In a progressive arrangement, use it first to intercept larger debris before water reaches denser mats. Keep large leaves and heavy solids from overwhelming the filter by maintaining any upstream screens or settlement stages.

Stage 2: Green — medium-density filtration

Green provides an intermediate structure between the black and blue grades. It can collect additional suspended debris and provide surfaces for beneficial bacteria as part of an established filtration system.

Stage 3: Blue — high-density filtration

Blue has a denser structure than green and can serve as a finer mechanical stage. Like the other grades, its fiber surfaces can support biological colonization under suitable operating conditions.

Stage 4: Grey — extra-high-density filtration

Grey is the densest of these four grades and can be placed last in a progressive AquaMesh / Matala arrangement. Monitor it for debris buildup and restricted flow. It is not a substitute for a separately specified micron-rated polishing medium where that level of filtration is needed.

Why use multiple filter mat densities?

Passing water through progressively denser media distributes debris capture across several stages. Larger solids are collected upstream so finer grades receive a lower load of coarse waste. This can help reduce premature clogging of downstream mats.

The outcome depends on proper installation. Fit mats securely, prevent water from bypassing them, and preserve the filter's intended flow path. More media is only useful if the system can still move water through it effectively.

Key features and benefits

• Rigid structure: Self-supporting mats make it easier to arrange distinct filtration stages.
• Mechanical and biological support: The fiber structure collects debris and provides colonization surfaces.
• Open flow paths: Water can pass through the mat while it remains appropriately maintained.
• Reusable construction: Clean intact mats according to product guidance and inspect them before reuse.
• Custom fitting: Mats can be trimmed with suitable tools to suit compatible filter chambers.

AquaMesh / Matala sizes and product codes

Use the following supplied size reference when planning your filter layout. Confirm the selected SKU, dimensions, and color with Lifegard before ordering or cutting.

Choosing and installing filter mats

1. Check compatibility. Match the media to the filter manufacturer's specifications, available space, and intended flow.
2. Measure before cutting. Allow for supports, pipework, and removal during maintenance.
3. Select the densities. Use a coarse-to-fine arrangement where your filter supports multiple stages.
4. Fit securely. Avoid gaps that allow bypass and do not compress the mats excessively.
5. Check operation. After startup, inspect water levels and flow, and make sure overflow protection remains clear.

Cleaning AquaMesh / Matala filter media

Inspect mats regularly and remove collected solids before flow becomes restricted. Follow the manufacturer's cleaning instructions. If a mat is supporting established biological filtration, rinse gently in removed pond or aquarium water, avoiding chlorinated water and cleaning chemicals.

Clean biological media in stages where practical, rather than aggressively cleaning every mat at once. Reinstall mats promptly and maintain suitable flow and oxygenation. Replace mats that are damaged or no longer fit securely.

Best applications

Consider AquaMesh / Matala for compatible koi pond filters, water gardens, filtration chambers, and custom biological filtration units. For aquaculture or larger installations, select the media as part of a system design that accounts for flow, solids loading, oxygen supply, and maintenance access.

Frequently asked questions

What order should AquaMesh / Matala colors go in?

A common progressive sequence is black, green, blue, then grey in the direction of water flow. This moves from extra low density to extra high density. Follow your filter's design and installation requirements.

Which color is the coarsest?

Black is the extra-low-density grade and the most open of these four options. Grey is the extra-high-density grade.

Does AquaMesh / Matala provide biological filtration?

It provides surfaces for beneficial bacteria to colonize. Biological performance depends on an established microbial community, suitable flow, oxygen, and water conditions; new mats need time to mature.

Do I need all four densities?

No. Select grades according to your filter design, debris load, and filtration goals. A four-stage arrangement is an option, not a requirement for every system.

Can AquaMesh / Matala mats be reused?

Yes, intact mats can be cleaned and reused according to product instructions. Replace damaged mats or those that can no longer be fitted securely.
