FINALLY get to set up my first pure fish tank in about 10yrs, everything has been a turtle/fish tank! I'm excited! It will have 2 tiger oscars as main inhabitants, and some undecided smaller SA fish. Tank is 100gal and will have an FX5. After much deliberation, media will be: ceramic rings, biomax, matrix, 10.5oz clearmax, 200ml purigen, filter pad(blue one offered by Fluval), then the included sponges. If someone has suggestions for additional filtration or suggested changes, I'd love to hear it! Thanks!
