Category: Aquarium CO2

Apart from light, aquatic plants need nutrients, not only nitrogen, potassium, phosphate and trace elements, but also carbon, which is essential for life. This is supplied not only by carbon dioxide in the air, but also by CO2, which is produced and carried in natural waters by microorganisms. In our biotope in the living space, however, there is often a lack of CO2, which can usually be seen in the sparse growth.  

Plants with a good CO2 supply are vital and show a more intensive colours. Increased oxygen production benefits the fish, shrimps and snails - the aquarium ecosystem in the living space looks more attractive and is more stable.

  • For improved growth of easy and medium plants
  • 60 days CO2 for a low cost
  • Safe to use
  • Easy to refill and recycle

Ellie C. ★★★★★

The pressure gauge is really handy for seeing exactly where the system is at, and I've got my rotala growing like crazy now. No more guesswork with liquid carbon dosing.

Claire ★★★★★

The regulator feels solidly built, and the bubble counter makes it easy to dial in a consistent rate for my 20-gallon tank. My Amazon sword finally stopped melting and is putting out new leaves.

Olivia ★★★★★

My rotala was pearling within two days of hooking this up, which I honestly didn't expect from a starter kit. The bubble counter makes it easy to see the CO2 is actually flowing, and the whole thing fits neatly behind my 20 gallon without looking like lab equipment.
