The Colombo 3 In 1 CO2 Diffuser consolidates three essential functions - check valve, bubble counter, and diffuser - into a single compact component. Its crystal-clear acrylic construction delivers complete visibility of CO2 flow dynamics and bubble production within your aquarium system. The integrated check valve prevents water backflow, whilst the bubble counter provides real-time visibility of CO2 enrichment, for accurate monitoring. The fine-mist diffuser maximises CO2 dissolution for superior plant growth.

Available in medium and large sizes to suit different tank volumes, the Colombo 3 In 1 CO2 Diffusers are compatible with most standard CO2 systems, allowing effortless integration into most setups. Designed for straightforward installation and hassle-free operation, Colombo Diffusers are an excellent choice for aquascapers seeking reliable, CO2 diffusion without unnecessary complexity.

Palletised Deliveries
Some large oversize products, typically items weighing more than 30kg, may require delivery via pallet and as such will arrive as a kerbside delivery only. The drivers in these instances are unfortunately not permitted to assist with the pallet beyond the drop off, and cannot aid in bringing packages into the property.

Pond Planet will contact you to book in delivery on a suitable working day. Delivery will generally take place between 9am and 5pm. To ensure there are no delays with delivery, please include a contact number when placing the order.
