So my buddy got a new higher gpd output unit and gave me his old 2 stage. Would it be necessary to add a di unit? I was thinking about buying the extra stuff and a new bracket cause i could probably do it for life 50 bucks. The unit was basically free. Gave him a couple colonies of Zs and Ps i didn't want.
