Coraline growth

But there is coralline that likes higher lighting, so what I would do is talk nice to some fellow reefers, and get some scrappings from tanks with good coralline growth under metal halide. Crush up the scrapings really good, then let fly in your tank, and it will help populate your tank with higher light coralline.

for the most part all coraline will do high light if introduced slowly as not to bleach it (coraline bleaches it is dead). what does happen is the color will change slightly. for example my dark red turned a pink color, my dark purple turned a light purple/pinkish , and my blue turned .... almost a mauve color.

what I would do is every now and then do a little scrape of the coraline in the sump so the spores will get blasted through out the rock in the main tank. it will take a while but it will start growing. I think my tank went 4 months after I killed all the coraline off before it started. then it went very slow for a couple months and now if I don't clean the glass it is solid. the light purple/pink is the dominant color in my tank under two 10K HQI 250 watt SE bulbs.
