I have an acro, not sure of species, that has incrusted an area of 4x4 and refuses to grow up and out? My calcium is at 390 which I know is low and everything else is in line, although my flow may be a little low in that area. Any ideas why it would incrust so much before growing up and out? It has been in this tank for about 3-4 months. I would like it to start growing instead of incrusting, but it is growing well just the wrong way.
Thanks in advance
