Reduced flow into the ReefMat, a kinked or collapsed section of hose, or a hose that's gone cloudy with biofilm that a wipe-down won't shift. A restricted inlet is also a common cause of a roller filter advancing fleece more often than it should — the sensor reacts to a slow chamber fill, not just a clogged mat.

This hose is sized for the ReefMat 1200. The ReefMat 250 uses a different part (R35483); the ReefMat 500's inlet hose is a separate part again — check with us if you're not sure which model you're ordering for.

Push-fit onto the unit's USA/metric connector, no tools required. Check the full hose run for kinks and biofilm at every fleece roll change — restricted inlet flow is easy to miss until the filter starts advancing fleece too often.

• Genuine hose connector kit (R35470) — fresh seals if you're replacing the connection as well as the hose.
• Red Sea ReefMat 1200 — the filter this hose is made for.

How do I know if my inlet hose needs replacing?

Look for kinks, splits, or a hose that's gone cloudy with biofilm that won't wipe clean. Reduced flow into the unit or more-frequent-than-usual fleece advances are also signs worth checking the hose over.

Will this fit a ReefMat 250 or 500?

No. The ReefMat 250 uses a different part number (R35483) and the 500 uses its own hose — this listing is for the 1200 only.

Does a longer or shorter hose change the flow rating?

The hose diameter, not length, is what the unit is designed around — keep the run as short and kink-free as your plumbing allows.
