KORALLEN-ZUCHT Cyano Clean 50 ml

Still just as effective, now that there is no more cyan, I use it as a preventive measure. Products that do not work like other so-called miracle products sold in the south of France at an exorbitant price and that do not work! (Translated review)

Very good, for me, it's the most effective product, my 800-liter tank was infested with cyano, a treatment of several months with Korallen-Zucht cyano clean and they disappeared! I tried other products much more expensive (French product made in the south) ... which I will not disclose the brand without results!!! (Translated review)

in process (Translated review)

Still being tested, but already in 3 days, a clear improvement (Translated review)

Nothing to say perfect (Translated review)

In trial too early to evaluate its effectiveness... still so much cyano after 5 days of use :( (Translated review)
