So I have a 75 gal reef tank, currently with a BTA, two mushrooms, and a blasto. So far they are all doing fine, but I did only add them 4 days ago. I was wondering what you would recommend for flow rate. Every source I have seen ether says x10 gph or x20 gph as a minimum. It seems to be 50/50, and I am not sure which is right. :fun5: Which would you recommend? I currently have about 900 gph flow rate in my tank. Thanks.
