Aqua Medic Round Grate 40mm – Black

Description

Aqua Medic Round Grate 40mm – Black — Smallest black grate for 40 mm drains, bulkheads and partitions

A standard 40 mm bulkhead or drain hole is sized for water, not for the snail, frag plug or clump of leaf litter that drifts toward it, and the smallest size in a range is easy to overlook until a blockage proves it was needed. Aqua Medic Round Grate 40mm – Black (SKU: AM41531) is the smallest of Aqua Medic’s three round grates, a black grille the maker describes as ideal for preventing larger detritus flowing through a strainer or overflow pipe, or for letting water pass through partitions in holding tanks while keeping livestock apart. Aqua Medic makes the grate in three diameters, Ø 40 mm, 50 mm and 63 mm, roughly 1.6, 2 and 2.5 in, and this is the 40 mm, the size that matches the narrower drains, bulkheads and strainer pipes found on smaller tanks and compact sumps.

Being black, it sits against black overflow boxes, dark bulkhead fittings and black sump hardware without standing out, which matters on a build where every other fitting in view is the same colour. The grate is sold purely by its diameter, so the hole or pipe it is meant to cover should be measured against 40 mm before fitting; a grille always takes up some of the opening’s open area, and trapped debris reduces it further, so the drain behind it needs a little spare capacity rather than running at its absolute limit. In a holding or frag system, the same 40 mm grate works equally well set into a partition, letting water exchange between compartments while keeping snails, frag plugs or juvenile fish on their own side. The 50 mm and 63 mm black grates in the same range cover larger openings, and all three sizes are also made in clear for builds where that finish suits better.

Usage & Application

When to Use

• Small bulkheads and strainers: 40 mm drains on smaller tanks and compact sumps.
• Holding-tank partitions: Water exchange between compartments without mixing livestock.
• Frag and quarantine systems: Keeping plugs and small animals out of a narrow drain.
• Black hardware: Matching black overflow boxes, bulkheads and sump fittings.

Placement & Care Guide

• Measure first: Check the hole or pipe opening against the 40 mm diameter before fitting.
• Seat it squarely: Fit the grate flush across the opening so nothing slips past the edge.
• Allow for flow: Leave spare drain capacity, since the grille reduces the open area.
• Clean regularly: Brush off trapped detritus at each service to keep water moving.
