Gfo and or phoz down will both upset the red field ratio. Making it hard for bacteria to effectively lower nutrients

Found this on Prodibio.

"BioPtim
This is your carbon source as found in many other ULN systems. The difference is again you only dose every two weeks. BioPtim contains a multitude of essentials additives for feeding the bacterial colony in your system and in doing so lowering your nitrates and PO4 levels."

Hmmm. Im still going to start with the Zeo carbon source product however. In addition to my Prodibio.
