Coraline growth
 

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.

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 :biggrin: And in a thread where Willow has posted :razz: That's just going to tick him off again :agrue:

Willow,

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

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