Aquarium Overflow Boxes
How to choose aquarium overflow boxes
Sub-type fit matters.
Fish Supplies like overflow combs protect shrimp, while the coolant tanks in this Pet Supplies range serve radiator builds.
Tank size drives the call.
Hanging drip boxes fit small aquariums, while wall mounted acrylic boxes suit larger fish tanks with circulating pumps.
Material changes the job.
Acrylic is light and clear, but silver metal serves expansion tanks that need leak resistance.
Colour affects upkeep.
Black combs blend into a tank, while silver boxes make a blockage easy to spot.

What's good
- Hanging drip flow boxes keep small aquariums silent without bulky hardware.
- Wall mounted acrylic return boxes let you run a circulating pump without using floor space.
- Overflow combs stop shrimp and small fish from getting pulled into the filter intake.
- Silver coolant expansion tanks give DIY builders a universal reservoir that resists leakage.
Things to watch
- Hanging boxes suit small tanks only, they cannot match the flow of wall mounted systems.
- Acrylic scratches faster than silver metal and shows algae growth more clearly.
- Universal coolant tanks need DIY fitting, they are not ready to hang on a fish tank.
- Black combs hide dirt, so you may miss a clog that an acrylic box would show at a glance.
Care & maintenance
Rinse acrylic overflow combs in old tank water each week to stop the weir blocking.
Wipe silver coolant reservoirs with a dry cloth to keep the metal free of grime.
Pull compact filtration drawer trays out and rinse the media to keep the flow quiet.
Check silver and acrylic engine coolant containers for cloudiness, as scratches trap sludge.
