Best phosphate remover out there I've heard is RowaPhos, but it's either almost twice as expensive as PhosBan, or it is twice as expensive as PhosBan. I'm using Phosban, and my salifert test kit shows a lot of phosphate, but I don't have any algae problems at all, and I also skim very wet on a very efficient skimmer for that size tank (ER 8-2 w/ sedra 9000, old style impeller). I've also got 1 tang, a foxface, and bunch of snails and mythax crabs, so they could be why I don't have an algae problem too. I also havn't had any nitrates either. Just phosphate. Maybe I should have someone else, or a store or something test it to double check.
