Dennerle Co2 QuickTest


$ 49.00 until FREE shipping


This one of my favorite new products. Simply add water to the test tube and shake and then compare to the color char to see how much co2 is in your planted tank. This kit has two tests. You only have to measure the water, the reagent is already inside of the tube.

Useful, but only two tests

This test accurately and quickly provides information on the saturation of CO2 in one's aquarium. My only complaint is that, when I bought, I failed to realize that only two tests come in a pack and that there are no refills. I contacted Dennerle directly, and they said there were no current plans for refills, either. With that in mind, it's hard to recommend these other than for an occasional spot test. Service from Aquarium CO-OP, however, was excellent and I highly recommend them as a source for aquarium supplies.
