Greenhair/skimmer

[13thmonkey]

is there a reason why i have green hair algea predominantly growing where my skimmer output is? i have a super skimmer for a 125 gal. it is a hang on tank set up.

Does it only grow there? If so is it really that big of a problem?

well it covers all the rock work there. about a third of my overall tank space. but yes only on the side that the skimmer is on.
