Pro-SE Series Complete Kit is a set of our most popular dual-stage ProDid you know!? The Pro-SE Series CO2 Regulator comes with a 5 year warranty and lifetime support! Why not to scape like a boss? SE CO2 Regulator, CO2Art In-line Diffuser and our best quality CO2 accessories. This System will provide you with all the necessary equipment to start injecting CO2 via an external canister filter.
The dual-stage construction of the Pro-SE CO2 Regulator minimizes the increase in output pressure as pressure drops in the gas cylinder and will prevent end-tank-dump keeping your livestock safe and the CO2 level stable.
This fantastic Pro-SE Series Complete Kit includes our best-rated In-line diffuser, allowing you to save more space inside the tank for lush and beautiful plants! This In-line diffuser is equipped with a replaceable ceramic membrane, producing tiny CO2 bubbles. It’s designed with Fine Mist Technology providing you with the best dissolution rates.
The Pro-SE Series Complete Kit contains also high-quality CO2 resistant polyurethane tubing which is compatible with all CO2Art products. It’s available in 5 colors and 3 lengths.
We also include the CO2Art Drop Checker Kit in all of our CO2 Complete Kits. The Drop Checker is a visual indicator of CO2 levels present in the water column. If the color in the drop checker glass chamber is lime green, the CO2 level in the water is safe for the aquarium.
