I just started my first build and have the water feature running while i wait for spring tails and plants to come. I noticed a lot of mold after the first few days.

Anything to worry about? I can take the little pieces that surround the water pond out and replace with cork bark, no problem. But its also forming on the bottom of my main piece that is my water fall.

PLEASE HELP!
