Coraline growth

McNasty · #1 03-08-2006, 04:10 PM

Just wondering what some tank and lighting specs are and Coraline growth every one has.

I myself can not grow coraline in my main tank.

Lighting consists of

4 t5
1 400 w 14k MH
1 175 w 12k MH

tank size 90 Gallon

Calcium 475
Alkinity 4.5 Meq
Magnesium 1325
PH 8.2

Now in my refugium , also close to my skimmer i am lighting with daylight compact flouresent bulbs and coraline grows fine.

Can you have to much light for coraline growth?

Weird.. I don't know for sure what's preventing it from forming.. but, I wouldn't be suprised if one day it just took over.

How long has the tank been setup?

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.

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.

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.

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

Lots of coralline growth on a 75g with 2X40w, same tank and 2X96w maybe a little slower.
