Anyone with a sps reef not use gac and not use a PO4 reactor?

I was told by some that my DSB, skimming, and water changes, along with possibly macro is all i need and that i should remove my 2 reactors(1 for carbon, the other for PO4)?

It depends if you need them or not.

If your DSB, skimming, water changes, and macroalgae leave your PO4 very low/undetected, no reason to run the reactor.

IMO, I'd always run the carbon reactor. It helps clear up the water, but then again, some people don't need them and run successful SPS tanks.
