I'm using aquaforest as a example there's many other carbon and bacteria products.

H Ryan, I have found the pro bio-s at J & l but it doesn't look like they carry the np pro. Just wondering where you get yours from? Would I need to dose anything else to get the tank balanced again? I have got my phosphates down to .5 now but I have been getting cyano off and on over the past year so I think that I do need to do what you and Warriordog have suggested to get the tank balanced again.
