I have fine sand in my reef. Since I have increased the flow in my tank the sand is making a mess. I am wondering what any of the experienced members are using for suubstrate in a mixed reef? I have a few sps up top, zoas, palys, bta, leather. Down low are several acans, favia, hammer, blastos, mushrooms ect... Tried adjusting flow but can't seem to make the sand storm stop. It is covering the tops of bottom corals which i have heard the fine sand can work is way under heads of acans, blastos and such and make them come loose. Having sand all over the top of them is probably not good for them either. So I'm wondering what substrate to replace my sand with for a higher flow tank? Any help would be appreciated. Thanks!
