Phosban Reactor Stupidity

[Myka]

Ya, I boil in RO/DI. Being the coal leftover from burning organics, most carbons will release some phosphates, although not a significant amount. Soaking will leach the phosphate, but boiling releases it quicker. I have been able to confirm this using a Merck test kit. When you boil it, depending on brand, there is often a kind of greasy film that goes on the pot at the water surface...not sure what that is, but I'm glad it doesn't make it to my tank!

Some people think boiling used carbon will clean it so you can use it again, but that is not the case.
