My tank was born in June of 09. I started it out all wrong with show coral instead of live rock "Long story - Bad Teacher" i have since removed most of the coral pieces and replaced with about 90 lbs LR added in the last 4 months. (Have more on order). I am using Spectrapure RO/DI and got my ASM G2 skimmer last night and got it up and running fine. This morning the collection cup was half full of "Ghost Buster looking slime". I feel I have everything in order EXCEPT for the lack of coraline and also there is always noticeable debris always floating around inside my tank???? Is this typical or should the water look invisible or crystle clear? Maybe the four Koralias are too much for my 180G???? I have my LFS dude to check my water every two weeks and he says my Alkalinity and Calcium levels are a Reefers dream and I'm being impatient. I see threads here all the time describing beatiful coraline and the purple back walls in just a few months Heck, Purple Up won't even work......what am i missing??
