Anyone have success in making a cage to contain their sea lettuce in the sump so it doesn't float over (smother) the other macroalgaes or clog the sump grates? We have sea lettuce, red ogo, and pom pom from Algae Barn. Pros/Cons, and ideas to ensure success? I'm not thrilled with the ogo, but the pom and the lettuce are growing great.
