Video sample of old culture tank

  • If you get a couple spoonfuls of sand and add to the tank then stir it up
  • rub the gunk/algae/sludge loose from the bottom of the tank.Like washing a pot or the dishes.
  • Then wait a week and syphon it out(or do a water change and collect the sediment that way) it should have a few eggs in.
  • Sort of clean the tank but let it all settle then collect it later on.
  • Waiting a week or maybe 2 should be fine because the tank is old.
  • Then it will take another 1 or 2weeks to dry on a plate/bowl.
  • It must be very very very dry or it rots/fungi/mould
