Ziss Aqua ZD-200 CO₂ Diffuser – Adjustable Micro Bubble Diffuser for Aquariums up to 200L

The Ziss Aqua ZD-200 CO₂ Diffuser is a high-efficiency diffuser designed for aquariums up to 200 liters, delivering ultra-fine CO₂ bubbles even at low pressure. Ideal for planted tank enthusiasts and aquascapers, it ensures optimal CO₂ distribution for lush, healthy plant growth.

Unlike traditional diffusers, the ZD-200 does not use a ceramic membrane. Instead, it features a unique felt ring that can be easily adjusted to control bubble size. Simply tighten or loosen the ring to increase or decrease bubble fineness. The ring is detachable, allowing for hassle-free cleaning and long-term use.

This smart diffuser also comes with an integrated bubble counter, so you can monitor and fine-tune your CO₂ input with precision. Built from durable polycarbonate resin, the ZD-200 is lightweight, compact, and virtually unbreakable, making it ideal for both hobbyists and professionals.
