Cooking and Curing Rock....

[hfp75]

Aug 12....

I took an old tank (60-65 gal) and put it up on my workbench and put in a pair of powerheads, filled it with water and got it running - with a working air stone. Then I put in all the cleaned rock. Due to the possibility of residual bleach I also put in a bunch of Prime.

Then today (a day later) I put in the rock that I was curing....... (on the right side - darker)

Now I'll let it run for a few days and change out some water, my garage is usually dark which will help decrease any unwanted algae growth.....

My goal is to get all the rock cycled and see what the PO4 is..... If I need to run ROWA then I will, but a few H2O changes should lower any residual PO4. My last residual test on the curing portion of the rock was PO4 of 0.5.
