I placed my order for a 180 gallon acrylic tank by truvue tonight. The dimensions will be 72X24X24. I will be receiving it in approximately 2-3 weeks. Out of curiousity, I know a few people are running 180 gallons and I wanted to know what you recommended for filtration and powerheads. I can get a undergravel filter that will fit, do you recommend this? I've heard mixed reviews on UG's. I don't really want hang on filters either. What do you think would be the best route to go in your opinions. This tank will be housing 9 red bellies ranging from 4-6 inches in length.
