Leaching phosphates from rock

[IanWR]

And THIS is what makes canreef such a cool resource! I don't know enought to even answer #2 ( I haven't heard of it, but it seems like I know about 5% of common knowledge). Is there any reason there would be any harm from a soak in bicarb solution?

Sorry for you that you seem to have spent a bunch of time that won't directly come out in your project, but I have enjoyed your posts regarding phosphates. Maybe you have enought to write an article for a reef publication?

Thanks for your work!
