Re: [APD] Carbon filtration, DOC & BGA

I haven't found DOC levels to be a cause of BGA -- jsut
imbalances of NO3 and PO4 -- which could be jsut what I
understand Tom to have said about nitrate levels and BGA.

But what you need to fix isn't the choice of media if your
DOC is too high.  And adding carbon would be superfluous if
the water changes are being done. If large
waterchange/resets don't work, then there are probably a
host of problems or imbalances to address such as a filter
that's gone too long without cleaning, way too many fish,
something overloading your tank.
