Too Much Coraline, what to do?

[Trigger Man]

i had that problem way back, I bought purple up, seeded from other tanks, and was gettign very little for coralline. Then one day it started to grow and quickly started covering everything, which in the end became a pain. Go figure, I worked so hard to get it, then when i got what I wanted I no longer wanted as much. Kinda reminds me of GSP i guess

You could probably fit a few more urchins into a 180gal. They're the only thing for sale that I know of that eats coraline algae... Tuxedos are good but I wouldn't bother with rock-boring as mine doesn't move around very much.

I found the best thing to mow down my coralline algae is a long spined urchin. I had a tuxedo and while he did eat coralline he never made much of a dent in it

I've always wondered how those things can even navigate a matured sps tank with all those spines?
