xPremium CO2 Diffusion for Planted Aquariums
The TWINSTAR CO2 Diffuser is built to endure busy setups while delivering precise, ultra-fine CO2 bubbles for freshwater tanks up to 120 gallons. Crafted from crystal-clear acrylic, it stays nearly invisible in your aquascape while its top-mounted, highly porous membrane ensures CO2 exits through multiple pores on top and along the sides. The result is a more even diffusion that helps nutrients reach plant tissue where they’re needed most, without overpowering the water column.
Designed with a focus on practicality and reliability, this diffuser pairs with all CO2 systems, including DIY configurations. The generous diffusion area and fine pearl-like bubbles help create a steady stream of carbon for your aquatic plants, supporting lush foregrounds and healthy mid-tones in your tank’s appearance. While outcomes depend on your setup and plant load, many hobbyists find the diffuser to be a flexible, low-maintenance upgrade that blends into the tank’s design as it works.

Setup and maintenance tips
Before first use, immerse the diffuser in water for about 10 minutes to displace trapped air. If you notice larger bubbles forming at the bottom, ensure the unit is fully primed before running CO2.
If bubble diffusion slows, remove the suction cup to prevent damage and follow maintenance guidance: soak the diffuser in a bleach solution for 10–30 minutes, then rinse thoroughly to remove any residue before re-installing.
Ideal use cases
