TROPICA CO2 System Nano Complete (Refill)

Description

TROPICA CO2 System Nano (Refill)

A Plant Growth System Nano is a desirable solution for precise CO2 dosage for small aquariums. CO2 addition benefits the growth of all plants and improves colour development.

A complete CO2 system with an elegant nano design
A precise and stable CO2 regulation
A 3-in-1 diffuser, which ensures a maximum CO2 efficiency

How to use the product

Ensure that the regulator is fully off before you mount the regulator on the CO2 cartridge.
Fill the diffuser-chamber with water.
Place the cartridge in the rack, slide the suction cups on the hose and mount the hose to the regulator and the diffuser.
Mount the diffuser with the suction cups at the inner side of the tank near the bottom and place the hose in the back corner.
Leave the diffuser for 24h in the tank to ensure that the ceramic disc is fully moistened.
Open the regulator carefully and count the number of bubbles per minute in the diffuser-chamber.
Wait 5 minutes, adjust and repeat until the number of bubbles per minute is similar to the recommendation in the table.

The table shows recommended dosage (bubbles per minute) in different tank sizes. A 95 g CO2 cartridge contains 50,000 ml CO2.
The most important nutrient for plants is CO2.
The natural CO2 level in an aquarium is 0-0.5 mg/L of water.
Even the slightest addition of CO2 can make a big difference improving the growth and vigour of the plants.
If the aquarium contains only slow-growing Easy-plants, the addition of CO2 gas into the water should reach a level of approx. 3 mg/L to ensure good growth conditions.
For Medium category plants the CO2 requirement is approximately 10 mg/L and for Advanced plants approx. 25 mg/L.
*) If you have a larger aquarium containing Medium or Advanced plants, the lifetime of a nano-cartridge will be too short. In this case we recommend a larger cylinder e.g. 2 kg refillable.
All figures are approximate.

Refilling your Tropica CO2 System Nano in Singapore

This is the replacement cartridge and parts set for hobbyists already running the Nano Complete kit, so you keep the same regulator and 3-in-1 diffuser and only swap what’s spent. For local keepers running a small planted tank, buying refills rather than a fresh unit each time keeps a low-tech nano scape affordable over the long run, which matters when shelf and storage space in an HDB flat is tight.

When fitting a new cartridge, make sure the regulator is fully off first so you don’t vent gas in one burst, then refill the diffuser chamber with water before reconnecting. In our warm 27-29C tanks the plants draw down CO2 briskly, so a cartridge may not last as long as the temperate-climate rating implies. Track usage with a drop checker so you can reorder before you run dry mid-week.

Our full CO2 systems range covers diffusers, tubing and check valves if you want to expand the rig. Beginners can read our aquarium CO2 guide and our drop checker and pH guide to keep dosing consistent between refills.
