I'm sorry but the benefit of purple up over normal stable calcium levels, is i'm sorry to say...and mean this with no ill will...all in your head.

I have thick coraline everywhere, the thickest though was always out of direct light....and by thick i mean it looked like the LR was melting off coraline..some places i could have chiseled 3 inches in and would still be at coraline...mind you that was on a tank that had flourished for years and years...coraline doesn't walways seem to grow in everyones tanks either...some immaculate tanks seem to have none, but the above was my opinion and some of the general consesus on coraline i have read over the years. But everyones tank is a completely different environment compared to even the tank in the nxt room. But with regards to purple up it is not snake oil, just overpriced. There are quite a few different types of coraline i've noticed over the years...although if they are different in any other way than the growth pattern they show i'm not sure.
