It could be that your lighting is too strong. I had only 200+watts NO lighting when I started my tank, and had some goreous coraline growth. I then added an additional 110watts CF and it does make a difference. Its depleating rapidly.

Also, do you have any heat issues? In my old tank, I noticed the coraline begin to decline when I added more light - but it was a heat issue. As soon as I lifted the fixure off the water a few inches and the tank's temp stopped creeping up too high, the coraline came back with a vengeance.

also, what about your alk?

Check your calcium, if your calcium is low this could effect the coralline growth....

There are different types of coraline (eg red, purple, white*, etc), some are more light hungry than others, as well as other parameters.

When switching environments, some coraline subspecies will die off, and others will start to grow. Its nothign to be worried about.


Hi first post here, hi all.
