<<<meq/L = ppm.>>> NOT!
I am not sure about using 2 buffers together. It depends on what the buffers are exactly, and I don't have experience with the Seachem ones. Way back in my undergrad years I can work out mixed buffer equations, and certain pKa's give discontinuous curves - ie the pH bounces up & down easily in the critical range. <This is what some people see using pH up/down ... a yo-yo-ing pH).
I know they make a neutral buffer (Seachem even have one), that might be a better idea. Seachem. Neutral Regulator FAQ
However, most fish can adapt to a wide range of pH. Here, tetras are kept in our tap water, which is pH 7.8 with KH of 200. Personally, I would think using cc is much easier than trying to doctor the water using all the other buffers. This is esp. when your tap already starts out at 7.6. It gets complicated trying to doctor that water if you ahve to do a large emergency water change. <Usually, people recommend using the commercial buffers only with Ro or DI water, to side step all the stuff in the tap.>
