Anyone else find it odd that Fauna have lumped Lanthanum in with carbon dosing, as in something to be dosed when the pH is high? There is a post somewhere recently on here that suggest the pH at the gill membrane can drop low enough to liberate the Lanthanum, causing issues. I expect this would be made worse if the bulk water pH was also low. No idea if that's true but sounds reasonable. Marc Levenson keeps suggesting raising Alk when dosing Lanthanum. I'm curious if Fauna have found a correlation during german trials, or if its just another story. Could be important, could be fluff.
