Green Tint???

[calirob]

Ok guys another question for you!
Tank is 3 months old. 125G with 180# LR. 3-250w MH on for 7 hours daily
Test are always perfect.....
So my question is:
I have no Coarline that I can see BUT when I turn the lights off (I still can see in the tank) and it looks like all the rocks have a Mint Green Tint to them. Almost like an Algea that isn't visible under the lights.
Is this the start to Coarline?
I hope so..I've been waiting....

Mine went from white to light brown to dark brown...then i started to see patches of coraline...

When my rock started, it went white to light green to purple. Just give it some more time, it will purple up.

I have had my tank up now for about 1 month and already have lots of coraline growing on my overflow box and some on the glass..

Lime Green to Purple...Can anybody else tell their story of getting the purple.....
Right now I see some lome green under the rock more than the top...but maybe the light is not lettign me see it during lighting hours..
I hope to have some purple soon, thats all my girlfriend wants to see. Then I've suceeded in the hobby according to her!
