yes, i'm aware of the "control" factors such as 0 phosphates, a good skimmer, clean up crews, water changes for nutrient export, reasonable lighting lengths, etc...but....for whatever reason I have a spot in one area of my tank that continuously grows the stuff no matter what I do (i.e. vacume it, pull out the algae)...so I was thinking of maybe a seastar or goby or "someone" to help keep it in check. My LR and equipment are always kept very clean by my hermits and snails, and whatever growth they miss on the glass I get myself...?
