Do you need Reactors to have a successful reef tank?

[Proteus]

I used reactors on my big tank but now I am us ring media bags just in sump. IMO reactors are better as they agitate the media rather than a bag in which fluid will take the easiest route through or around. I do plan on buying a new reactor for gfo. But carbon ill leave in the bag.

What type of reactors are you thinking? I run a Ca reactor, a Zeo reactor, but not a GAC reactor nor any other type.

I run GFO and carbon in reactors just because it keeps my sump nice and neat.

Was thinking a ca reactor but can someone explain to me why they are needed

What's a Zeo or gac

I was dosing calcium, alk and magnesium manually. A calcium reactor basically slowly dissolves coral skeletons and re-introduces that Calcium and alk back into the system. I set mine up back in Aug. and I've never looked back. Way easier than manual or individual dosing and far better stability because it adds these elements 24/7
