Hey Ed, Hope all is well. I was just wondering if you could help me out with some advice? I am sorry to bug you, but i still can't forget who awesome your tank looked the day i was there. I can only imagine how you elos tank looks. MY question is about the sand bed. I am getting advice to go with a plenum, But i kind of remember your having a shallow sand bed. I will be using arag live as my sand bed. So any feedback will be greatly appreciated. MY filtration will be a swc dnw 150, 62lbs of lr for now and will ehiem 1260 rp would that be enough as rp? There will be a small refugium in the sump also. Thanks and have a great day.
