I just set up my first refugium. I'm using a sand bed with some frags of lr. Currently I have some culerpa floating in it but I just ordered some cheato to replace it.
There is a great deal of red, film-like algae in the compartment. It's trapped there. The sponge filtering the water flow to the return compartment catches it all. But there is quite a bit of it. Should this be? Is there a problem I'm not catching here?
Also, the water hardly seems to circulate in the refugium. It seems to skim across the top of the compartment and out. Should I consider doing something to create some gentle circulation in the 'fuge? Maybe an air stone?
