Hello everyone,

I recently constructed my first paludarium, which will eventually house some dart frogs. I came here because I need help with the water portion of my project. Recently I've noticed quite a bit of white/yellow-ish foam collecting on the surface under one of the waterfalls. I was wondering if anyone could provide some advice for removing this foam?

here are some photos:

I appreciate it!
