CO2 Drop Checkers are used for long-term monitoring of the CO2 levels in the aquarium. A CO2 reagent is filled into those CO2 Drop Checkers and will change the color according to the amount of dissolved CO2 in the aquarium water. Green will indicate a proper CO2 value, yellow will indicate to much CO2 and blue will show not enough CO2.

Please note that the required CO2 Drop Checker reagent is sold separately and does not come with this glass CO2 Drop Checker.

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.

High quality
26th February 2018

It takes more time to show the CO2 level in the aquarium, maybe about 3 hours, but this is not such a problem.

Very nice accessory for our tanks!

Very nice looking glassware. No more problems with suction cups, it just hangs from the edge of the tank. (read more)
