Not that I have been reefing for that long, but my guess is that the iron-hydroxide based phosphate removal compounds (Phosgard / RowaPhos) that have come along recently are a huge improvement in reef-keeping technology. Even though you are basically buying high purity "rust" at a ridiculas price, the stuff really does work well. When you consider what it can do for your tank if you have excess phosphate, you just cant beat it.
I never even bought a reactor. I just rinse the material in RO/DI water, put it in a mesh bag, and place it my sump (I have a strainer compartment built into my sump). I have also run it through an external cannister filter (Fluval 404) with good results.
I just love the stuff and what it does for my tank!
