mixing salts?

[purplesprite]

I know someone has done this?Im about to do a water change and need to raise my calcium.I usually add a two part buffer, but im fresh out.My question is could Iuse Oceanic salt to raise my Ca. when i regularly use IO. In my mind its a two for one.

Oceanic mixes up at about 600ppm Ca, IO is at ~400. If your Alk/dKH is stable and a little high, then Ocenic should be OK. Check after and add dKH buffer if needed.
