I'm having Coraline issues as well, but my problem is much different that yours.; then again, in order to properly grow Coraline algae, you need to maintain proper Calcium levels. I hear that 400ppm is a good target, although some may differ slightly. Try this out and see if you get different results: tech your display tank for calcium, KH
, and phosphate, and also test the water in your refugium. Since your Coraline "appears" to grow more in your refugium, your calcium level could be at a perfect level. If the level on your display tank is too high, then that could be your issue. Common sense say's that both results should be the same, but you just neer know.
My personal issue with the lack of Coraline is that my Calcium is only 300ppm. In a weeks time, I should be able to see that number in the low 400's... Then after that I will begin to seed my tank with Coraline from some frags of Corals that I will purchase from my vendor. Seems like a simple plan, but what ever goes according to plan these days?
