dark green hairy algae?
so i have had my stem setup for about three months now and jsut started adding ferts saturday. all was going well untill yesterday when i noticed small tufts of hairy deepgreen almost blue hairy algae growing on my plants and only my plants. it isnt growing on any of my rocks or driftwood.
x1 flourish comprehensive
x1 flourish iron
x2 flourish potassium
and that was all since saturday after a 50% waterchange
light is 54 watt t5 6.7k hagen tube x2 over the length of the aquarium
55 gallons standard size 48 long 24 high etc etc
use a HOB filter no carbon just sponge
photo period before algae was 11-12 hours
no co2 or co2 additives such as excel
since algae ive dropped it down to 8, well today even with the reduced photo period the algae has seemed to get worse so im not sure what to do. the algae does rub off fairy easy but seems to be worse in the creveces of the plants I.E at nodes of the stems on stem plants and on rims of leafs.
