Mja... Easycarbo innehåller tydligen polymeriserad glutaraldehyd.

Wikipedia har detta att säga om glutaraldehyd: "Though not marketed as such due to federal regulations, the biocidal effect of glutaraldehyde kills most algae at concentrations of 0.5 - 5.0 ppm. These levels are not harmful to most aquatic fauna and flora. Adverse reactions have been observed by some aquarists at these concentrations in some aquatic mosses, liverworts, and vascular plants."

Easycarbo alltså göder växter, men är dödligt för vissa alger och mossor.
