Skimmer foam differences

I have a refugium pro that has a built in skimmer and it pulls some nasty brown stuff along with brown/blackish water. It's a small built-in skimmer that comes with the fuge.
Now I just added a TurboFlotor Multi SL by aquamedic and it's making TONS of foam, but the water is coming out green.
Is there any differences in the water color each one of them is pulling out?
