Default Re: Cladophora algae and Fissidens

Systemic dosing of 2-3ml/gallon of H2O2 worked for me, at those levels it won't kill or hurt fissidens but will turn kill the clado. Keep it up for several days to make sure you get it all. Once in the morning and once in the evening. I haven't tested the limit of fissidens, but its over 3ml/G.
