I am sorry it took me so long to reply. I am supposed to get notified when I get a question, I'm gonna have to fix that.
As far as the hair algae goes, I recommend getting 1-2 hermits per gallon to help get rid of algae problems. They will eat anything and keep the tank very clean when they are hungry. Eventually they might eat each other but the tank will be very clean. That plus keeping nitrates at zero and phosphates low will keep your tank free of algae and pristine.
As far as the EcoAqualizer goes that thing is basically a PVC tube with some magnets in it from what I understand. It's supposed to ionize the water somehow. Maybe it has some effect but I really doubt it does much.
As far as bio balls go, they convert ambient organic matter into nitrates. If you get an Aquaripure then the Aquaripure needs to be the primary biological filter and you will need to get rid of other biological filtration.
You will want to get the Large Aquaripure and when used properly it will replace up to a 90 gallon a week water change. You will also want to get more fish! Up to 10-15 small/medium fish in a 180 gallon is appropriate for a reef tank with the Aquaripure.
You have a beautiful tank, you clearly have put a tremendous effort into it. There is no reason for it to be even more beautiful AND easy to take care of.
If you do get the Aquaripure be sure to send me before and after pictures in say 6 months.
