I currently have an API freshwater kit but getting low on ammonia, nitrite and nitrate. The saltwater kit is around a third cheaper. Googling leads me to believe that the bottles are the same in both (i acknowledge you only get high range pH in the saltwater kit)
Can anyone confirm the bottles are the same product?
I understand the colour chart may be different on the saltwater one too, but not sure how or why but not relevant as i have the FW kit.
