Well i just bought a 100g flat back/hex front acrylic and pretty much I want to set it up the way the guy has it setup now. From what i saw he had a 55 gal on the ground for a sump. There was 3 stages setup in the tank for the water to flow. Then i believe it was the skimmer then back up to the tank. Then on the side was a 5 gal bucket and he had a gauge in the 55 so when the 55 got low it would turn on and take water out of the 5 gal bucket. Then there was an RO system and lighting was a pair of metal halide. So can someone help guide me to getting decent stuff? Right now i have a 55 salt water so im a bit familiar with this stuff.
