minimal coraline growth

[mvm]

I've had my 34 cube set up for quite a while, and the coraline hasn't really taken off, but all of my sps are growing well. Are they out competing the coraline. My last test:
cal ~400
mag ~1100
kh 10

Am I missing something? I have a 250 W lumenarc with a phoenix 14k bulb. Is my lighting too brite? The tank is BB and there is none growing on the bottom glass either...

You might think about raising you cal just a little other then that may go scrape off someone else's tank

took mine 4 months with purple up 3 times a week, finally its really growing all over

raise your mag a little, don't use purple up, and lower your phosphates. Give it time.

Yeah, I'd say the lower magnesium may be the real key. Up it a little.

Flying army has all you need. Lol

I definetely could scrape a ton off and save it for you. Just let me know if you want some and I'll try to catch as much as I can when I go on my scraping rampage!

I tried that and it worked really well. I also ended up with tons of little feather dusters.
