How prevent scum in a bubble cloner???

  1. Title sums it up.
  2. Is it (bubble cloner) light tight? What temperature is the solution? Scum generally occurs from light leaks and/or high temps in the solution.
  3. Adding a small dose of hydrogen peroxide will clear up your problem....but, its better to make it light-proof like chunk said.
  4. What chunky said. Add more air stones, light proof it, and regularly change the water.
