Lots of calcium but no Coraline!

[daugherty]

most all my coraline is on the under sides of things

[NewbReefer]

what kinda lighting do you have Daugherty?

[daugherty]

four 96w pc and 1-175w 14k mh on a 50gal tank

[NewbReefer]

very nice, is that a fixture or a retro kit you put together? what brands?

[daugherty]

the pc's were a retro from custom sea life that i got about 8 years ago and the mh is a retro also not shure from where i dont remember. but i get great growth from my corals ecexpt the mushrooms that i have they stay pretty small and the coraline that i do get on the back of the tank turns white. but i have started to get some orange coraline.

[NewbReefer]

wow! orange? now thats a coraline color i've never seen before. very neat.

[daugherty]

it is strange it starts to grow quickly then it all turns white then starts to grow again over the old growth it is really different.

Suppliers of coralline covered live rock would of course try to povide rock that would please the majority of its purchasers, sadly if you provide good and intense light you are not of the majority. The majority provide pretty dismal lighting. As a resort the suppliers provide rock that allows those with dismal lighting to still be successful. This typically means corraline covered rock that does not require intense lighting, IE. rocks from depths of 30 or 40 feet or more. I do not in general have any coraline on the tops of most of my rocks in the top half of a 2 foot deep tank running 250 HQI halides with PC actinic supplemental. I myself would be very happy to pay some one to send me coraline scrapings from the tops of rocks that are kept under intense lighting. Any color or thickness.

indeed, so then does it just take a long time to get that coraline to grow in IE? or is it a different type of coraline that if you dont have introduced into your tank your SOL unless you can find someone to give you some to seed from?

[daugherty]

as far as i know you need to find rock that is not very deep in the water or someone that has it already i have looked for the rock on the net but have never found anything yet.
