Pod Block

Pod Block is a stackable copepod habitat designed for reef systems that need a more structured place for pods to settle and stay established.

Each block measures 180 mm (7.09 in) x 80 mm (3.15 in) x 75 mm (2.95 in) and is 3D printed in PETG. The top and bottom feature an interlocking connection pattern that lets you stack multiple units together into a larger pod refuge while keeping the footprint compact and easy to place.

Pod Block is made for use in sumps, overflows, refugiums, and all-in-one chambers where protected habitat can help support more stable pod populations without adding unnecessary complexity to the system.

Key Features

Stackable modular design for expanding pod habitat

Interlocking top and bottom geometry for secure connection between blocks

3D printed PETG construction

Designed for sumps, overflows, refugiums, and AIO chambers

Compact footprint with usable internal shelter space for pods

Why Use Pod Block

Creates a more protected area for copepods inside filtration zones

Makes it easy to build a larger refuge with multiple connected blocks

Adds structured habitat without taking up excessive space

Works as a simple hardware solution for systems that benefit from dedicated pod shelter

Placement
Place Pod Block in a sump, overflow, refugium, or all-in-one chamber where water movement can carry pods through the structure without turning the area into a high-turbulence zone. Seed with live pods as needed and leave the block in place as a dedicated habitat area.
