The Bleu3D PodTopia™ is a high-density copepod habitat designed to maximize the number of safe spaces where pods can hide, reproduce, and thrive inside your aquarium system.

While maintaining the same compact 2" × 2" footprint, PodTopia dramatically increases pod habitat density by incorporating twice as many openings as the original PodHaven design. This creates a dense network of protected micro-channels that allow copepods to establish stable populations away from predators.

Place PodTopia in a sump, refugium, or low-flow area of your system and it quickly becomes a thriving micro-ecosystem. When it's time to feed, simply remove the block and release a concentrated burst of pods directly into your display tank.

Key Features

Ultra-Dense Pod Habitat

PodTopia features twice the number of habitat openings compared to PodHaven, creating significantly more protected spaces for copepods to colonize and reproduce.

Expanded Surface Area

With approximately 148 square inches of internal habitat surface, PodTopia provides an extremely efficient environment for growing and sustaining pod populations.

Oversized Retrieval Loop

A larger integrated loop makes it easy to attach a string or line, allowing quick retrieval from deep sumps or refugiums.

Perfect for tanks where the sump chamber may be 18 inches deep or more.

Drop It In — It Sinks Instantly

PodTopia is built with a solid internal structure, allowing it to sink immediately and stay planted on the bottom of your sump or refugium.

No floating. No drifting. Just drop it in and let the pods move in.

Reef-Safe Construction

Manufactured using 100% PETG, a durable and reef-safe material suitable for long-term saltwater aquarium use.

Ideal For Pod-Eating Fish

PodTopia helps maintain the live food supply needed by fish that rely heavily on copepods, including:

• Mandarin dragonets

• Scooter blennies

• Leopard wrasses

• Six-line wrasses

• Other pod-hunting reef fish

Maintaining a strong pod population is critical for these species, and PodTopia helps create a renewable pod reservoir within your aquarium system.

How to Use

1. Place PodTopia in your sump, refugium, or low-flow area.

3. When ready to feed, remove the block and shake or rinse it in the display tank to release pods.

4. Return it to the sump so the pod population can rebuild.

PodTopia vs PodHaven

PodTopia is designed for reef keepers who want maximum pod habitat within the same compact footprint.
