| Re: Purple up??? i have it also, and aragamilk which is made by the same people. i got the purple up for free in a raffle. i can't really tell much of a difference between the two. ground up calcium carbonate skeletons and whatnot. not sure if any of it actually works to get the coraline growing. i've been reefing for about 3.5 years and have never had much coraline growth despite having correct water parameters for it. i wont say that it hurts anything, but there are better products to spend your money on. |
