Best Supplement for Coraline growth?

[likwid]

Hey guys,

I'm placing an order with Ocean Aquatics, and am looking for a supplement that will give me accelerated coraline growth. At the moment I have coraline that already came on my liverock, but no more has grown in my tank in the 4 months that it has been up. I have not used any supplements at all, so I'm guessing my calcium isnt where it should be. Which products would be best for coraline growth and anything else. I heard Kent is a good brand and OA has a great selection of their products.

Thanks
