That WAS very informative and quite interesting!
I switched over to this 29 on October 22nd, and in a little over 3 months, I have more coralline than I had in a year in my 14. I'll have to post comparison pics in my diary thread. The purple is all over my rocks and on the back walls, there is lots of purple and green coralline, more concentrated where the intake grates are. I've been pretty happy with how fast it's growing in my tank. Of course, I also dose 2.5ml of Purple Up every other day too, so wonder if that has anything to do with it?
Purple up will only help if your magnesium levels are in check, and alkalinity but thats an obvious one. Magnesium often goes unchecked but is a very important element in the process of coral propogation.
It has been shown that coraline algea prefers the blue'er spectrum of light. So running your actinics for a while before your daylights and for a while after the daylights shut off can help. You should see an increase in growth of your coraline. I read that somewhere online and switched my light schedule to run at least an hour of actinic only morning and night and I noticed an improvment of my coraline growth.
