Seachem buffers confusing me.
For the Seachem buffers (Acid and Alkaline Buffer), I'm using RO/DI water to mix up 10 gallons of replacement water at a time. Tank residents are/will be Microdevario kubotai, Boraras brigittae, Brachydanio/Danio tinwini, and Coydoras pygmaeus, and cherry shrimp. At the moment, I'm trying to figure out how to mix the buffers to get a stable pH of 7.0 (to be turned to 6.5 once I figure this stuff out and get the first two species which favor more acidic water). Do I mix the buffers at a ratio of weights? Or do I mix the buffers per dosage? For example, the Alk Buffer says to add 1 tsp/10 gallons to raise the pH, and the Acid Buffer says to add 1/4 tsp/20 gallons to lower the pH. The ratio on the cans says 2 parts alkaline buffer to 1 part acid buffer for a target pH of 7.0. Does this mean that for 10 gallons, I add 2 tsp Alk buffer to 1/8 tsp Acid Buffer (what I've been doing for about the past year with the danios, shrimp, and corydoras)? Or does this mean that I need to use 2 tsp Alk buffer to 1 tsp Acid buffer?
Additionally, since I need to keep the KH and GH high enough to prevent rapid changes in pH, what's a good target alkalinity (I'm assuming GH which also has KH included) to aim for with these low alkalinity fish?
So many fish to keep, not enough aquaria.
