Before it goes in

  • Eco-Complete is a gravel, 0.3–7 mm grain.
  • It is lightly fertilised: root feeders grow in it without root tabs.
  • It is pH-neutral: whatever comes out of your tap is what the tank sits at.
  • It releases no ammonia, so livestock can go in as soon as the tank is cycled.
  • It suits Neocaridina, which want harder water than Caridina do.
