What's your planned water change routine for this new tank? If you're willing to remove and replace half the tank water weekly, you could mix lava rock and polished pea gravel as the substrate. Add some floating plants like Anacharis, Hornwort and Water lettuce. Use two large air stones and two air pumps to run the stones. I like Active Aqua pumps. The lava rock is home to the bacteria and the air stones maintain the oxygen in the water. The water change will act as the filtration system. So, no mechanical filters are needed. I set up this system on my 300 gallon tank and the system works extremely well to keep the fish healthy. I keep Goldfish and Fat Head minnows. If the system works for heavy waste users and oxygen producers, it should work for other fish.
