Coralline Growth

[Gizmo]

Any hints to get coralline growth happening?

I've had by smaller tank (20G) for 2 years and there is absolutly no growth, and I'm concerned about the 70, had it since Jan and it has also no hint of coralline growth.

Thanks

Where else do you want it?

Back glass. I saw at Big Als their display aquarium had it and some form of grass type coral grew over it. I think it maks a great natural background.

I would say your Ca is a little high, maybe let it drop to about 400ppm
