I'm receiving my Pukani rock from BRS today. I'm going to cure it in a covered Brute barrel as everyone suggests with a heater and pump. I have a few questions. Can it be cured outside without a heater in the barrel? Do I use saltwater, tap water, or RODI?

Rodi saltwater over fresh imo just so the rock cycles as well as cures, the heater I don't know if your really going to need it depending on the ambient temp. The pump is needed, you'll want high current to help dislodge any old organic material.
With pukani since it has a lot of organics on it it I would first rinse with bleach water. Then clean it off with rodi very well. Get some acid from the hardware store and give it a dip in there. Again rinsing with rodi after. Then use fresh saltwater to cure and cycle it. You will have a PO4 issue if you just throw it in a bin to cure t.

For my pukani rock, I used muriatic acid bath first. Then rinsed it with a hose and threw it in saltwater in Brute can in the garage and dosed lanthanum chloride every other day. Did maybe 2 water changes in 9 or 10 weeks. Zero phosphate/algae issues in the year that it has been in my tank.
