I have only been keeping a reef for about 2yrs. And I never post. Although I feel as if I have tons of experience due to my looonng hours lurking various groups. When I have problems or concerns, I can usually search around and someone has already had that problem-and solved it via groups. So while my years in the hobby are not nearly that as some of the oldhands around here, and I can probably count my posts on 1 hand, I would not discredit myself as a newbie, or someone wet behind the ears. I find that I am much more informed than 99% of lfs. To sum it all -I believe that good judgement comes from experience, and experience comes from BAD JUDGEMENT-no matter whos bad judgement :wink: So I never take one persons opinion as truth or fact, no matter how much of an "expert" but just take it into consideration with the overwhelming different views found, then based on my own research and observations, form my own opnions.
