properly tune a skimmer - how to?!

[reefwars]

tuning skimmers for me has always been a bit of a pan in the butt to find that sweet spot, i use a marker to mark where it is and i adjust it from that mark so as i have a reference point to work with.when your tuning remember it takes several minutes for your skimmer to really adjust so dont go nuts on your adjusting....my vertex is very sensitive like a quater inch turn makes a huge difference.you also need to decide if you want a wet skim or dry...i prefer dry skim but everybodys got their preference
