Do reactors equal less water changes?

[GoFish]

Sorry for the delayed specifics, had a busy weekend

I was actually referring to WC's to reduce nitrates and phosphates VS reactors using GFO, carbon, bio pellets/balls etc... Taking care of Mag/Alk/Cal are dosed using Magnesion and C Balance part A+B (thats the extent of my dosing done). The tank uses a refugium, skimmer and filter socks currently to reduce bio load, and i don't run GFO. Until mrhasan touched on calcium reactors i hadn't done any research into them to know what they were even used for. Since reading up on them they make sense! Just not sure if they're worth the cost setup and space VS using dosing pumps + C Balance, we'll see.

So far it seems no matter how many setups i've seen with hundreds or thousands of dollars in equipment over and above what i have, people still do WC's from 5-100%. Auto water change systems such as the Genesis appear to accomplish the most of what i'm looking for, space however is the issue

Oh what a joy it must be to have a dedicated equipment room!
