Before it goes in

  • Pool Filter Sand is a sand, 0.5–0.6 mm grain.
  • It is inert: it holds no nutrients of its own. Root feeders such as Cryptocoryne wendtii and Dwarf Hairgrass Mini need root tabs under them.
  • 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.
