I have really bad tap water so I run it through a RO system, then to get the ph to around 6.5 and keep kh and gh around 4 I add co2 and seachem equilibrium and alkalinity buffer. What I am wondering is since I can't use my tap water to equalize my ro, has anybody used a remineralizing cartridge after the ro to stabilize the ph,kh and gh.

Yes I use a remineralizing filter. It adds back about +2 to KH & GH. I further condition with MgS04, CaS04, and K2C03 to get to 4 KH 6 GH. Many ways to get there. The dry ferts are a cheap way to do it.
