ok the best i can describe it is black hair algea. it completly covers my leafs on almost all my plants and cant be taken off the leaf without ruining the plant. it doesnt seem to be killing the plant just making it look really bad. i have a 10 gallon with 22 wats of lighting and no co2. and i also have a 5 gallon tank with 22 watts of lighting but it is raised off the tank so it isnt such a concentrated amout of light. both seem to be having the problem. i also have a 20 gallon but that one isnt nearly as bad as the rest. the 20 gallon only has 15 watts. can light be causing it? if so what can i do to counter it? i have a pic of what it looks like. i have giant hygro in all my tanks and that is the one it is doing it on i think because it has larger leaves.
