Aquarium Water Change Diffuser for Rimless Fish Tanks (Black, Medium)
- This water change diffuser converts strong water flow into a wide, gentle stream to prevent splashing and overflowing. The internal sponge filter provides an additional layer of flow diffusion, protecting substrate, plants, and decorations while making every water change clean and controlled.
- Universal & Secure Fit: Equipped with an adjustable screw clip, this diffuser easily attaches to rimless aquariums (glass or acrylic). The clip accommodates various tank thicknesses for a firm and reliable hold.
- Scratch-Safe, Durable PETG Construction: Made from high-quality PETG material, 3D-printed for precision and durability. The diffuser is gentle on delicate tank surfaces while providing long-lasting performance for daily use.
- Protects Substrate, Plants & Decorations: By diffusing water flow, the diffuser prevents disturbance to delicate plants, substrate, and decorations. Ideal for betta fish, shrimp, and aquascapes where a gentle water change is essential.
- Easy to Use, Clean & Store: Disassembles in seconds for compact, space-saving storage. Quick rinse and reuse, making routine aquarium maintenance effortless.

Directions
Step 1: Insert the included plastic screw into the adjustment slot. For first-time use, the screw may feel slightly tight. This is normal and will loosen with repeated use. Loosen the screw to create enough space for the aquarium rim. Step 2: Place the diffuser onto the edge of the aquarium, aligning it with the tank rim. Step 3: Hand-tighten the plastic screw until the diffuser is firmly secured in place. Do not overtighten. Step 4: Position the water hose above the diffuser and begin the water change.
