Gold Buffer vs Alkaline Buffer
Short summary: Which is better to use for a guppy tank: Gold Buffer or Alkaline buffer? Note: Tank is not planted, substrate is inert.
Long version: Water here in north Atlanta comes out of the tap at 0 KH, and I adjust to a PH of 7.5, KH=11, by adding 3 parts Gold buffer to 1 part Proper PH 7.5 (the Proper PH, which should regulate to 7.5 by itself, doesn't do that in this water and stays at PH=7.0 instead. It needs the Gold Buffer for some reason). I also add a bit of Epsom salt, and a teaspoon of aquarium salt per 3 gallons.
This has worked for me, but I wonder if using alkaline buffer instead of gold buffer would be better for the guppies? What is the difference between the two products?
