Hioa about using a 12" high kiddie pool. Add some cc in one area, make a dsb in a 1/4 of it and use the rest as a reguium area and an area for heaters and proten skimmer. Use a couple of PHs to move water to any dead areas.
Pick up a few detrivore kits (IPSF, Inalnad Aquatics,, etc).
Then you can sell detrivore kits to others at is matures and you need to trim the macro.
