Overview
Legend Sol™ CO2 Diffuser Acrylic Series is a premium in-tank CO2 atomizer designed to provide exceptional carbon dioxide dissolution while maintaining a clean and modern appearance inside the aquarium. Combining a durable acrylic diffusion chamber with a precision nano-ceramic membrane, Sol™ transforms pressurized CO2 into an ultra-fine mist of microscopic bubbles that dissolve rapidly into the surrounding water.
Efficient carbon dioxide delivery is one of the most important factors in achieving healthy aquatic plant growth, vibrant coloration, and stable long-term aquarium performance. The nano-porous ceramic membrane utilized in Sol™ creates significantly smaller bubbles than conventional diffusers, increasing the surface area available for gas exchange and improving overall CO2 absorption efficiency.
Unlike fragile glass diffusers that can be easily damaged during maintenance, the robust acrylic construction offers improved durability while preserving excellent optical clarity. The integrated bubble counter and diffuser chamber design allow aquarists to monitor CO2 delivery while simultaneously maximizing diffusion performance within a single compact unit.
The replaceable ceramic membrane simplifies long-term maintenance and helps ensure consistent performance throughout the life of the diffuser. Combined with the integrated check valve system and corrosion-resistant stainless-steel support structure, Sol™ provides a reliable and elegant solution suitable for both beginner planted aquarium enthusiasts and advanced aquascaping systems.
Directions
Position the diffuser inside the aquarium in an area with moderate water circulation to ensure efficient distribution of dissolved carbon dioxide throughout the aquarium. Connect the CO2 tubing securely to the integrated inlet and verify that all connections are properly installed before operation.
Before introducing CO2 pressure, allow the ceramic membrane to remain submerged in aquarium water for approximately two hours. This soaking period enables water to penetrate the microscopic pores of the ceramic membrane and improves diffusion efficiency during initial operation.
For best results, adjust the regulator to a working pressure of approximately 2 bar or higher. Once pressure is applied, several minutes may be required before carbon dioxide begins passing uniformly through the ceramic membrane. During the first hours of operation, larger bubbles may be visible around portions of the membrane. This is a normal characteristic of new ceramic diffusers and will gradually improve as the membrane becomes fully saturated.
Over the first twenty-four hours of operation, the diffuser will progressively produce finer and more uniform microbubbles as all ceramic pores become fully conditioned. CO2 levels should always be adjusted gradually and monitored using a suitable CO2 indicator or drop checker to ensure safe conditions for fish, shrimp, and other aquatic livestock.

Maintenance
Over time, algae growth, mineral deposits, and organic residues may accumulate on the ceramic membrane and reduce diffusion efficiency. When bubble size increases noticeably or CO2 output becomes less uniform, cleaning should be performed.
Remove the ceramic assembly and immerse it in a solution consisting of equal parts household chlorine bleach and water. Allow the membrane to soak until deposits have dissolved completely. Cleaning duration will vary depending on the severity of contamination.
After cleaning, rinse thoroughly with clean water and allow any remaining chlorine residue to dissipate completely before reinstalling the diffuser. Once properly cleaned, the ceramic membrane will typically regain near-original diffusion performance.
Regular maintenance helps preserve maximum atomization efficiency and extends the service life of the diffuser.
FAQ
Why does the diffuser produce larger bubbles when first installed?
New ceramic membranes contain microscopic air pockets that must be displaced by water. During the initial conditioning period, larger bubbles may be produced until the membrane becomes fully saturated. This process typically completes within the first twenty-four hours of operation.
What advantages does a nano-ceramic membrane provide?
Nano-ceramic technology creates significantly smaller CO2 bubbles than conventional diffusion materials. The increased surface area allows carbon dioxide to dissolve more efficiently into the water, improving plant availability while reducing gas waste.
Why is a minimum pressure recommended?
The microscopic pores of the ceramic membrane require sufficient pressure to distribute carbon dioxide evenly across the entire diffusion surface. Stable operating pressure helps maintain consistent bubble size and diffusion performance.
Is the diffuser suitable for shrimp aquariums?
Yes. Sol™ can be safely used in aquariums containing shrimp and sensitive livestock when CO2 levels are adjusted responsibly and monitored appropriately.
How often should the ceramic membrane be cleaned?
Cleaning frequency depends on aquarium conditions, lighting intensity, nutrient availability, and algae growth. Reduced diffusion performance, larger bubble formation, or visible deposits on the membrane generally indicate that maintenance is required.
Can the ceramic membrane be replaced?
The diffuser is designed with a removable membrane assembly, allowing worn or damaged ceramic elements to be replaced without replacing the entire diffuser.
Why is the bubble counter integrated into the diffuser?
The integrated design allows aquarists to monitor CO2 delivery directly at the point of diffusion while reducing the number of separate components required within the aquarium system.
Safety
For aquarium use only. Keep out of reach of children. Use only with properly regulated pressurized CO2 equipment. Excessive pressure may damage aquarium equipment or tubing connections. Always verify that all tubing, fittings, and connections are secure before operation.
Monitor aquarium inhabitants carefully whenever CO2 levels are adjusted. Excessive carbon dioxide concentrations may cause respiratory distress in fish, shrimp, and other aquatic organisms. Increase CO2 gradually and maintain appropriate water circulation throughout the aquarium.
Do not expose acrylic components to strong solvents, abrasive cleaners, or excessive mechanical force. Although more durable than glass, acrylic surfaces may become scratched or damaged if handled improperly.
Disconnect the CO2 supply before performing maintenance, cleaning, or membrane replacement. After cleaning, rinse all components thoroughly before returning the diffuser to service. If cleaning with chlorine-based products, ensure all residual chlorine is completely removed before reinstallation.
