I don't like that Hagen Mini E filter because the f-media is too small.

Looks like the white slime is taken over your sponge instead of the B-bacteria.

When you rinse it out, the white slime still dominates a majority of the sponge that why it grows back 1st.
  • Are the snails & guppy nibbling on the white stuff?
  • What are you feeding the guppy?
  • What are you using for the source of ammonia?
