MM is not all about growing algae, the algae is optional,
The mud feed the algae and it adds minerals/vitamins to tank.
I have a number of tanks with algae and they dont grow as fast and are not rich in colour like the algae that is the Mud.
Mico algae will grow in any tank but not at the same rate, you do want it to grow fast so it can remove organics in the tank.
Not sure, its a type caulerpa. not taxifolio
