An elegant handmade glass indicator, usable without any suction cup. Hand made with high quality glass, the CO2 Indicator can be cleaned easily using bleaching agent when dotted with algae. Indicator Solution is sold separately. Rinse glass piece thoroughly before putting it back to use.

Maintaining the appropriate CO2 level is critical in a planted aquarium. Too much CO2 may harm your fish, whereas too little CO2 decreases plant growth and allows algae to take over. The CO2 indicator makes it easy for you to know the CO2 level inside the aquarium by comparing the color of the reagent.

  • Transparent suction cup included

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.

19th August 2016

Ich habe nun mittlerweile 2 dieser schönen, schlichten und unauffälligen Orb Checker in meinen Becken und bin im Großen und Ganzen zufrieden! (read more)

sehr schönes Design
6th April 2016

Dieser Orb Checker sieht nicht nur gut aus sondern ist auch leicht zu handhaben. Für kleine Aquarien unter 30L evtl. nicht so zu empfehlen, da dieser etwas groß wirken kann.

Echter Hingucker!
7th February 2016

Optisch mal was anderes als die üblichen CO2 Checker. Find ich sehr angenehm. Das Einfüllen der Indikatorflüssigkeit ist ist mit den entsprechenden Tools eine Leichtigkeit.
