This will be my first tank build that is all new and starting from scratch. All of my other tanks were purchased already set up and just moved and reset up. I have a 180 set up now so I will be downsizing, but it’s an upgrade in my opinion. I’m pretty excited to see the difference it makes if any. It is the Red Sea 425 deluxe. I will be using Marco shelf dry rock and dry sand. Still trying to figure out which sand we want to use. This tank is going in my office and a buddy of mine that works with me is helping with the build. So it is both of ours tank and I think it will be easier on maintenance with both of us taking care of it. Here are some pictures so far. We did a mock set up with the rock and trying to decide which aquascape we want to go with. They both look good to me so it’s a hard decision. What do you guys think?
