The TetraPlant CO2 Optimat provides an economical and controlled way to enrich the water with carbon dioxide.
It is simple to install and refills are available. The in-tank dispenser is simply filled with CO2 from the canister and the carbon dioxide gas dissipates into the aquarium throughout the day.
The release of CO2 not only produces lush plant growth but also prevents lime scale deposits on the glass and plant leaves. Additionally, it can help to keep the pH values within a favourable range.
The 11gm CO2 canister is suitable for tanks up to 100 litres in size
- Easy way to enrich aquarium water with CO2
- Aquatic plants develop more strongly
- Healthy plant growth enriches the water with oxygen improving fish health
- Prevents lime deposits on leaves and glass
- Consists of 11g CO2 depot, diffusion tube and connection tube
- CO2 container contains enough CO2 to allow in-tank diffuser to be filled approximately 50 times
- CO2 Depot available as a refill
- For aquariums up to 100 litres

Could you tell us if the pocket of gas left each evening in the diffuser pipe of the Tetra c02 Optimat, which your instruction manual says is oxygen and nitrogen, would be harmful to fish or plants if left unvented. The reason for the question is the position of the diffuser pipe in our aquarium is not easy to get to, and therefore turning it upside down to release this gas pocket is very difficult. When the diffuser pipe is filled each day does the new CO2 gas push out the remaining oxygen and nitrogen gas from the day before? We note in the instruction manual it says the diffuser pipe must be placed 5 to 15 cm below the surface of the water. But there is no explanation as to the effects of placing it 5 to 15 cm below the water. Does the tube Empty quicker at five then it does it 15 etcetera?We Replied:
Dear Mr Bertram, Thank you for your question The nitrogen and oxygen gases that can accumulate in the CO2 diffusion pipe are certainly not harmful to fish. 70% of the air we breathe is nitrogen gas, which is inert. Fish can experience problems with gas supersaturation but this only occurs when large quantities of gas are forced into the water, or when groundwater is brought to the surface quickly which does not allow the gases time to depressurise. Neither of these circumstances are relevant here. The only issue the presence of these gases in your diffuser could cause would be that they could displace the CO2 thereby lowering the effective dose into the tank with each application. Regarding the placement of the diffuser in the tank, the 5-15cm depth is optimal, too high and too much of the CO2 gas can be lost to the air at the surface, too low and the elevated water pressure increases the loss of CO2 from the diffuser. Hence our trials have shown that the quoted figures were optimal. Should you wish to contact us further or to place an order, please call us on 0121 355 7701.
