What's your secret to getting all the coraline algae to grow in your tank? You did say only 2 months old right? My 29BC has been up and running for over 1.5 years and I don't have any.
What kind of salt are you using, what chemicals are you adding, have you made any mods to it like pump/lighting etc etc?
I just swapped my tank around over a week ago, took out all the livestock and corals, removed the old rock and replaced it with nice fiji rock and swapped out the crushed coral for a nice shallow sand bed. Tank looks so much better now and I just started using Reef Crystals salt on Monday. I was orginally using premixed saltwater from my LFS and I believe they were using Crystal Sea salt which I've heard is pretty good but after 1.5 years...you would think I would have some purple in my tank. I had a tuxedo urchin which I've heard will eat coraline but I would think I would have seen a little bit at least.
I'll have to post some pics of my tank. I even modded out the center chamber by removing the bio balls, replaced with rubble rock and then some chaeto and added lighting for it to grow, replaced the stock pump with a maxijet 1200 with 2 koralias in the tank for good flow.
