The CO2 Orb Counter guarantees a precise control of your CO2 supply. As it is made of glass, this CO2 bubble counter blends into your CO2 equipment smoothly and unobtrusively. With its help you can realise the optimal number of CO2 bubbles for perfect water plant growth.

The included attractive glass check valve does not safeguard your CO2 supplying system but prevents water from leaking from the bubble counter.


  • with high-quality ceramic membrane
  • made of glass
  • compatible with pressurised gas cylinders and limited compatibility with biological CO2 supplying systems (biological CO2 supplying systems need to produce at least a pressure of 1 bar)
  • with connection for commercially available 4/6mm CO2 tubing
  • transparent suction cups included


  • fill the bubble counter with water
  • use tubing to connect the CO2 supplying system with the check valve
  • connect the check valve to the lower part of the bubble counter (the check valve should be rather close to the bubble counter)
  • connect the outflow of the bubble counter with the CO2 diffuser or reactor

Installation order

  1. CO2 Bottle
  2. solenoid valve (if available)
  3. CO2 proof check valve (to protect the CO2 system)
  4. Glass check valve
  5. Bubble counter
  6. Diffuser

We recommend to use soft silicone tubing to connect the glassware in order to reduce the risk of glass breakage. The piece of hose used should be kept as short as possible in order to avoid unnecessary CO2 losses.
Silicone hose is not pressure resistant and therefore can not be used for connection to the pressure regulator.

Aquasabi is our own brand, under which we offer high-quality products with a very good price-performance ratio. Carefully selected CO2 diffusers, CO2 bubble counters or lily pipes are just some of the items we sell under this brand and which will surely add to the value und the beauty of any aquascape. For this reason, many aquascapers and planted tank enthusiasts use products by Aquasabi.

Besides the good price-performance ratio, our main focus is on the satisfaction of our customers. This is the reason why our doors are always open for those who need help with our products.

When it comes to special aquatic plants, water plants from Aquasabi are just the thing for you. We offer rarities from our own cultivating tanks or import them specifically. These plants are otherwise hard to come by, and most of them cannot be purchased from other shops. We have high quality standards, which make Aquasabi plants a good choice for aquascapers, planted tank enthusiasts and aquatic plant collectors who want to enrich their tanks with rare aquatic plants. Special mosses, particular stem plants, hard-to-come-by ferns or very rare forms of the genus Bucephalandra are only a few of the plants we are proud to offer.

Klein aber fein...
17th August 2014

... ist dieser Counter, ein wenig fummelig in der Installation, wenn der Schlauch aber erst mal sitzt, sitzt er ;OD Nicht so klobig wie andere Counter, fällt bei meinem 250 Ltr. (read more)

klare Kaufempfehlung

Hab das erste mal Glasware bestellt und ich muss sagen ich würde sie immer wieder bestellen. Blasenzähler gut verarbeitet und man sehr gut die Blasen abzählen. (read more)

Greifer der Saugnäpfe zu kurz
25th September 2017

Glas ist gut verarbeitet, aber die Greifer der Saugnäpfe sind für den Counter zu kurz, da die Glaskugel so breit ist, dass die Greifer nicht an die Glasrohre heranreichen.
