Modular Aquarium Filter Baffle | 2-in-1 Gentle Flow Diffuser for Bettas & Planted Tanks

Tame the current and protect your fish with our Modular Aquarium Overflow Baffle. Standard power filters often create a harsh downward current that can stress sensitive fish, uproot plants, or disturb your substrate. This 3D-printed, two-part system gives you total control over your tank's surface agitation and flow direction.

Key Features:

Dual-Stage Diffusion: Use the Base Overflow Box (Black) to break the initial fall of water, allowing it to fill and spill gently over three sides for maximum dispersion.

Surface Glide Attachment: Snap on the Sloped Extension (White) to redirect flow forward. The curved ramp guides water along the surface, promoting gas exchange without the "waterfall" impact.

Fish-Safe Design: Ideal for Bettas, Axolotls, Fancy Goldfish, and shrimp who prefer calm waters.

Easy Installation: Features integrated mounts for standard suction cups (included) for a secure, adjustable fit under any HOB (Hang-On-Back) filter.

Size: Currently 5in x 2.5in (122mm x 60mm)

Modular & Sleek: Low-profile design that blends into your aquarium background.

Material: 3D Printed with Aquarium-safe plastic (PETG).

Includes: 1 Base Overflow Box, 1 Sloped Extension, and 2 suction cups.
