Little info: keeping goldfish in soft tap water with practically zero k h. I added crushed Coral and it'll raise kh a little bit but not too high, my pH tends to be around 6.8 so I'm wondering what other options are the best. Equilibrium makes zero sense to me because I do not have plants in my tank, so I was considering seachem gold buffer or API proper pH 7.5 any recommendations?
I like that the API product also serves as a water conditioner, but with seachem I'd still have to use a dechlorinator
