View Full Version : Coralline Destroying Live Rock??????

This quote came from a guy in Lisbon and I forgot his name, however, the thread was about coralline algae. This comment is about the growth of it destroying the live rock.
"coralline not all that good! In my tank it over took all the rock and the glass I use 150 pounds in my 75g as most of my filter with the power heads blowing on it when coralline covers all the rock it covers the holes in the rock stopping most of the filtering in the rock."
Has anyone heard of this before and is it tue???
I have a truckload of this stuff growing in my tank and if it is true then I need to slow this stuff down somehow.
Randy does this make sense and do you think it has any creedence?
Regards,
Pat

here is a pic of coralline under the scope. <a href="http://photobucket.com" target="_blank"><img src="http://i5.photobucket.com/albums/y178/salwaterfish123/coraline.jpg" border="0" alt="Photobucket - Video and Image Hosting"></a>
Do you think bacteria can get through it? :)

I agree with the premise that the pores of live rock might get sealed over with coralline if there is a lot of coralline growth, but coralline only grows in light exposed areas. The undersides of rocks, and any shaded rock further down in a pile is almost always coralline free, IME. I would not like it if my exposed rock were the grey brown color of live rock without coralline.

Sorry I dont understand.Do you think coralline is a problem to live rock filtration?

yes and no. It may block access to much of the internal surfaces on rock that it is totally covering.

But since a good portion of my rock and most rock in a reef tank is free from a lot of the direct light and therefore coralline free based on that premise the rock is still able to process waste on/in the surfaces that are free from coralline?
Does this then also lend credence to the notion that live rock must be periodically replaced with new rock?

In the 10+ year old tank that I recently took down, by far the majority of live rock surfaces were not coralline covered due to being in dark areas, even though there was extensive coralline growth on the exposed surfaces.

I definitely think you SHOULD get rid of some. Send it my way, I'll take care of it for you.:D
