Well for all 6 of us with calcium reactors I as wondering if you noticed and changes in coral health or coloration after you switched. Everything in my tank is growing better since the switch. Which was kinda excepted with the far more stable parameter in the tank but somethings did surprise me. For one the few softy I have seem to be happier with better polyp extension. The other was a few of my SPS coral started fluorescing better. The most obvious was my Monti danae which show a green fluorescents that it just hinted at before the switch. If I can find a before pic I will post some before and after pics. I am wondering what your experiences where went you switched?
