The HOT Magnum with the Pro 30 would work for a 29 FO
tank. I think you may have some nitrate issues using this setup though. I would suggest using 45-60lbs of LR
and a sandbed consisting of sugar sized sand about 4" deep. Inoculate the sand with some good live sand from an established reef tank if you can. Read the articles here about the Berlin system of filtration and do a search on DSB
's as well. I would look into a skimmer too. The Aqua C Remora with a surface skimmer would be perfect for a tank this size.
