id say there is nothing wrong with a foam filter (i would recomend a fiber filter you can inexpensivly through away, over a reusable filter) and bio balls, no hurry. i run fiber filter and a huge biowheel (its the size a coffee can) and carbon 24/7. also a diy
anoxic denitrator. i havent done a water change in over 4 months (i will do a 10% soon) my nitrates test 0 (no color change) just keep every thing clean be consistant or change slowly. and lots of water flow.
there is a book showcasing private tanks from around the country. it includes all of the owners parameters. the only consistant things were: lighting amounts above the normal recomondation, higher than normal water flow, and stable water params. all other things were wildly different.
