Hello everyone, my name is Rob. I guess you could say that I am new to the hobby.... again. I haven't had a tank in over ten years. Obviously technology has changed since I had my 150 gallon tank. My Wife and I have been doing some renovations to the home and we have decided that we want to get back into keeping a marine aquarium again. I have been trying to design a setup over the weekend because we are about to move forward. I am doing a custom built in wall unit. I want the tank 72L x 36H x 24D = roughly 280 gallons. Jut curious what everyone is using for various types of equipment now a days. i.e pumps, sumps/fuge, skimmers, calcium reactors, chemicals, etc. whats hot, whats not. new ideas or ways of keeping a tank with a mix of fish and coral. Basically, anything that can aid me in my design and build process. I prefer to do as much as I can myself so any good knowledge that could be passed on would be great. thanks.
