Would that get rid of the phosphate in the rock? I know that would get rid of organics.. Also, not sure if that would lower the Alk from the cement.
Regardless, It would have been hard for me to cook 200 LB of rock..
Mine was all dead real live rock so I didn’t have to worry about alk. Also no issues with phosphate as it seems to absorb it maybe. I struggle to keep nutrients in my system and have fought dinos because of it. Started my last tank 15 years ago with with all real live rock and had no issues
