I am usually ok with a little cyano on my fuge, but there is a ton, I am going to by pass the fuge currently and run some chemi-clean in it and let the power heads do their thing, I might throw my hob skimmer on it to not tax the other skimmer when let it flow back into the system.
my light cycle is about 12 hours on the fuge with the h380, my nutrients are pretty low at .25-5ppm nitrate (dosing to raise) and .08 po4
