Coraline growth

Yes, lots of coralline is low-light coralline, which explains why your fuge has in and your display does not.

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.

Interesting. Thanks for that.. learned something new today.

try some purple up, i lost a lot of coraline when i switched bulbs. i started doseing purple up and within 2 weeks i was scraping it off the glass.

tanks been running 2.5 years, tried purple up I get little patchs, BUt i would expect alot more growth with parms I keep,. I does magnisum alot to keep it up where it should be, I have goptten some coraline from others perhaps I need more.

My pinksih coraline only grows in the display tank where there is minimal light (i.e. behind the LR, under the overflow box, etc).

The back of my tank is painted blue, so it reflects a lot of the light. I bet if it were black, coraline would grow all over it.

One Word: Magnesium

I had my tank running for 3 years w/o coralline, After a visit to Bev's place, and the talk I got about no one measuring or adding magnesium to their tank, I got going on it. Within one month I have a huge patch of it on the back of my tank where the water flow is the strongest. MAGNESIUM! - Thanks Bev

Giz,

OMGosh! My name and magnesium in the same sentence

And in a thread where Willow has posted

That's just going to tick him off again

Willow,

Sorry to poke fun at you, but it's just too easy not to sometimes

Anyway, time to be serious. Who makes purple up and what's in it?

Ok, forget Mg, his level is fine, one thing I noticed is the Ca level is way to high, try slowly dropping your Ca to about 400ppm and maintain it there.

another thing is Alk, what is 4.5 Meq in normal measurements?

I keep mine up around 11Dkh.

isn't it funny I have been touting the merits of Mg for about 3 or 4 years now and Bev starts last year and is famous for it

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.

I get huge coraline growth under my PC's and under my MH and I do dose with MG. It totally covers my equipment 1st but vinigar takes it right off. Every once in a while I scrape it off and let it grow back as you can see on righthand side of 29G
