I think things are pretty dialed in right now in my tank and it feels like growth is pretty good right now. I use to think it was a slow grower but I have seen a lot of growth over the last month that I haven't experienced before. If others are growing fast for you it might do the same but who knows, you know acros can be, hahahaHow do they grow for you, I have avoided it as I have heard it is a super slow grower.
