i've noticed that you'll find that in this hobby...lol
in my case, i use information here, and also talk to my LFS..
my LFS takes care of the tanks at a local casino, and maintain a few of the local pro ball players tanks..so they dont view me as a cash cow...and they have alot of expierience..
so, you might want to look around your area and find someone similar..
my thoughts are, i can get alot of opinions here, but if my LFS steers me wrong, i can go "have a chat" with them...lol
