For folks with soft water tanks, I would go with Javalee's prescription for bringing GH up in softwater tanks:
Add CaCl2 and MgSO4 (Epsom Salts) in a 4:1 ratio (approximately).

These are two different things. Adding CaCl2 and MgSO4 in a 4:1 ratio by volume will yield a Ca:Mg ratio of about 13:1 in ppm. It's my understanding that a Ca:Mg ratio of 1:1 in ppm is best, which takes a CaCl2:MgSO4 ratio of about 1:3 by volume. See:
