I've run sulphur denitrifiers for years now and can safely say that they do not reintroduce phosphates into your system. But the catch is the bioload you have. These types of nitrate reactors are great for low to medium bioload tanks. What it really comes down to is how much nitrogen you are adding to your tank.
The korallin units are well built and can take a beating. The sulphur pellets last for years and the only byproduct is nitrogen that you have to bleed off. But even that depends on the amount of nitrates in your system.
Here's another unit I'm thinking of trying
