Aqua Medic Round Grate 63mm – Clear — Wide clear grate that guards large drains while staying discreet in glass overflows
A large external glass overflow is meant to be looked through, and a black grate in the middle of it spoils the view the builder paid for. Aqua Medic Round Grate 63mm – Clear (SKU: AM41543) is the largest of Aqua Medic’s round grates in the clear version, a round grille that the maker describes as ideal for preventing larger detritus flowing through. The range runs Ø 40 mm, 50 mm and 63 mm (about 1.6, 2 and 2.5 in), and this 63 mm grate, roughly 2.5 in, covers the widest openings: high-flow drains, big strainer pipes and pass-throughs in larger sumps and holding systems. Water flows freely through the grille while fish, snails, frag plugs and lumps of macroalgae are kept back.
The clear grille lets light through and makes trapped material easy to see, so it is obvious when the drain needs attention. Because it is sized by diameter, the opening it will cover should be checked against 63 mm before fitting. A wide grate keeps more open area than a small one, which matters on drains handling the full flow of a large return pump, but anything caught on it still cuts capacity, so overflow levels are worth watching after fitting and again before each service. In multi-compartment holding tanks it lets water move between sections without letting animals wander. The 40 mm clear grate suits narrower openings, and black versions are made where a dark fitting blends better.
Usage & Application
When to Use
- Glass and external overflows: Large clear boxes where a black fitting would stand out.
- High-flow drains: Openings around 63 mm on bigger reef and fish-only systems.
- Large sumps: Keeps bulky debris and stray livestock from pumps.
- Holding tanks: Partitions between larger compartments in shop or fish-room systems.
Placement & Care Guide
- Check the size: Measure the opening against the 63 mm diameter.
- Fit it square: Seat the grate evenly so no gap opens at the edge.
- Test at full flow: Run the return pump at full output and watch the overflow level.
- Keep it clear: Lift out and rinse when debris shows through the grille.
