Hopefully somewhat different question though a search on cooking rock brings up A LOT of entries.
Building fishroom prior to 180g build, planning on buying BRS pukani rock and know concerns about phosphate leaching. Question: since I have nothing but time before I have physical tank set up can I buy 200lbs +/- rock and just soak it in RODI water for the months I have before use? Does it need to be saltwater or fresh for the soak? Surely no need for heater or circ. pump at this early stage? Will freshwater be just as effective at leaching out the phosphates? Would like to avoid acid wash if it will be unnecessary after a looong soak.
Appreciate your input!
