So, little update....
August 10....
For the rock that was curing I have been regularly changing the water out with my old tank water. My tanks params are usually about P04 <.1 and NO3 of 20-50 depending on my last water change. Initially My air stone wasn’t working right so it had a bit of a fowl smell (aerobic vs anaerobic) - but burning NO3, the initial PO4 after soaking with this rock was 1.0 !!!!
After changing the airstone out for one that worked the fowl smell has gone away and and after a few water changes my saturation on PO4 is 0.5 so, we are on the way. There is no visible algae on any of this rock any more. It has been under a black thick garbage bag - no light.
For the rock that I cleaned and an going to bake.... it has all been acid washed and bleached. It has also been dried and is just waiting in boxes....
