I did it the way that BRS recommended. Just let it soak in salt water (with circulation) for a good while and do water changes. Having said that, my rock has been soaking for over a year (while waiting for the tank) and there are still phosphates present (0.2 last time I checked). I only did a couple of water changes though. I am now running GFO on the container. Need to do some more water changes, starting soon. Getting closer to tank set up.
You might want to consider the acid bath, but be very careful. I imagine acid would do a number on the Pukani if soaked too long.
Yea... I'm not too keen on messing with acid.
I'll just soak the rock, and maybe put something in the container that will pull or absorb phosphates. I wasn't planning to soak them but about 6 weeks. I'm a little concerned that you've been soaking yours for a year, and you're still seeing measurable phosphates.
I'm almost regretting buying Pukani Rock now.
Maybe I should have gotten something else.
