Thank you! I'll just sit and wait. I hope it will grow a good amount of algae to compete with the algae in the display tank. Unfortunately I still have a bunch of hair algae on the back of the glass and also on the substrate for some time now. It bothers me a bit. Maybe I should add a devider to the sump area? Right underneath the scrubber. If I can direct the water flow towards the scrubber, all of the water must pass the algae first. what do you think santa monica? In theory this will direct many times more water than the airlift.
