Re: [APD] Activated Carbon and the Dangers of email

[Elaine T <ethompson77 at yahoo_com>]

Just a quick note about carbons and phosphate.  This is a reef tank 
trick, where excess phosphate can definitely cause problems.  You can 
test for phosphate leaching by dropping a few grains of the carbon in a 
phosphate test kit set up with tap water.  Some brands are a lot worse 
than others. I've seen brands where the carbon grains leave blue trails 
as they sink into the test kit vial, and other brands where the test kit 
vial remains completely clear.  The ones that don't turn the phosphate 
test blue worked well in my reef, so I'd assume they would work well in 
freshwater for folks who want tight control of phosphate levels.
