A great deal more than I do, I would think. But not marine biology, just knowledge of fish-tank water chemistry, like
---how Prime splits chloramine into chlorine and ammonia
---the equilibrium of ammonia <---> ammonium depending on pH
---the difference between KH and GH
---how carbonate and bi-carbonite determine buffering capacity
And stuff. This is nor a test. And I'm not trying to showoff (as if I could).
The forum just lost it's water chemist, and I'm having a hard time carrying his water. I'm trying to see who I can ask for direction, and in what areas.
