Aqua Medic Overflow Comb 32 Incl. Holder
A gap-toothed comb screens overflow water, keeping fish inside the tank. This 32 cm overflow comb fits across the top of an overflow box, its teeth spaced to let water pass evenly while keeping fish, plants and larger debris out of the drain. It ships with a holder designed to be glued permanently to the overflow, for installations where a removable clip isn't needed.
Key features
- 32 cm comb, ~2.2 cm tooth spacing — sized for standard overflow box widths, letting water flow through evenly rather than pooling at the gaps.
- Includes glue-on holder — for a permanent fitting to the overflow box, rather than a removable clip.
- Keeps fish and debris out of the drain — screens the overflow without meaningfully restricting flow.
- Compatible with Combfix — Aqua Medic's optional flexible holder accessory, if you'd rather not glue the comb in place (Combfix sold separately).

Common questions
Is the holder glued in permanently?
Yes — the included holder is designed to be glued to the overflow box for a permanent fit. If you'd prefer a removable option, Aqua Medic's Combfix accessory or the clip-fit Overflow Comb 40 don't require glue.
What size overflow does it suit?
The comb itself is approximately 32 cm long with roughly 2.2 cm tooth spacing, suited to standard overflow box widths around that size.
Does it stop fish going over the overflow?
It screens out fish and larger debris while letting water pass evenly through the gaps, though very small fry can still pass through.
Is glue included?
No — you'll need an aquarium-safe silicone to fix the holder to the overflow box.
