Thinking ahead before I get my tank.

If you put the cheato macroalgae in the middle chamber then what stops it being washed through and into the next chamber?

Is there a grating or something you need, what stops the whole thing clogging up?

My tank has arrived. Looking at the chambers I still can't see how you can retain the macroalgae in the middle chamber without the flow trying to push it into chamber 3.

Has anyone got any thoughts PLEASE.
