Before it goes in

  • ADA Amazonia Light is an aquasoil.
  • It is lightly fertilised: root feeders grow in it without root tabs.
  • It pulls pH and KH down, which suits soft-water shrimp and most plants. It also works against hardscape that raises hardness — Seiryu Stone and Elephant Skin Stone — so the two partly cancel out.
  • It leaches ammonia for the first weeks. Cycle the tank on it before any shrimp or fish go in — this is the single most common way a new tank on it goes wrong.
  • It is rough on fish that sift the substrate. Something finer suits German Blue Ram and Julii Cory better.
