How to rid the tank of hair algae?

The first thing is to eliminate Phosphates from the system. Twin phosban reactors have been running for a month now. I can't yet measure phosphate accurately enough to know if they are working or not, but the theory is solid.

Grow algae somewhere else. I have now added a refugium to the system. The idea here is to run the light over the refugium nearly 24 hours/day so that this algae uses up the available nutrients first. Because this algae is in one spot, it is easy to harvest as it grows. (all this explanation is because I have non-aquarists who enjoy following my tank saga)


Finally, you have to go on the attack to eliminate the hair algae from the main tank. To that end, I have added two sea hares and some more urchins. The sea hares are very effective at mowing hair algae. (photo to follow) Should the sea hares ever successfully eat all the algae, I'll return them to the fish shop so that they can help someone else out.
