Pricy, but worth every dollar to me. $599.00 for my 65 Gal Rectangular. Powered by a Rio 1700 pump; turnover rate 10X's hr. Keeping ammonia down to .15 consistently, with 20% water changes every 2 weeks. Important to keep the water level in tank full; within 1 inch from top, or the water level inside Rio pump compartment drops down to the pump. Pump then spits air bubbles and you don't want an eventual burnout. Just add H20 for your normal evaporation and you will be fine. Fairly quiet filter operation with the bio-ball system; a lot quieter than my Magnum 350 w 2 Bio-wheels. Use my tank wooden stand now for inside storage. When placing this tank, leave room to reach in to right side of filter compartment (Rio Pump) for occassional cleaning or eventual replacement. Enjoy!
