N-Fit M adapters are designed to make your N-Clear M Filter drop-in ready for supported tanks.

For unused standard 4-inch filter sock openings, use the N-Fit 4″ Filter Sock Opening Cover.

N-Fit Adapter M1012

Innovative Marine 30, 40, 50 AIO. Use the bare adapter without the two water blockers.

N-Fit Adapter M1212

For installing the N-Clear M in Innovative Marine SR 60, 80 and 120 AIO tanks when the original mounting adapter is missing. This optional adapter is designed for the N-Clear M, not for holding a standard 4-inch filter sock.

N-Fit Adapter M1216

Waterbox 65.4 AIO and the older Waterbox 50 Peninsula (not the Waterbox 50.3 rear-chamber AIO)

N-Fit Adapter M1218

Fits most 7″ × 4.5″ rectangular filter sock openings, such as the Eshopps Mariner series

Fit requirements

Adapter fit depends on the complete chamber geometry, support surface, depth, and clearance—not opening width alone.

Other tanks

If your tank uses a standard 4-inch filter sock opening, the N-Clear M usually drops in without an adapter. For unused openings, use the N-Fit 4″ Filter Sock Opening Cover. For other tanks, reach out at support@naturedimensions.com with the exact tank model plus clear photos and measurements of the filter area.
We’re constantly expanding our adapter lineup to support more tank models.

Custom adapter orders: Before we make a custom adapter, we will send you the exact adapter design and measurements. Please double-check that the design fits your tank before we produce it.
