What were the actual results? I use Equilibrium. My tap water is soft at 4/5 gh/kh. After each weekly water change, a half teaspoon is added, shrimp molt and reproduce just fine. You can add ember tetras and pigmy cories to the suitable livestock list. In my 5 gallon, I have very young true Siamese algae eater and long fin albino pleco. When they surpass the 2 inch mark, they'll be exchanged for smaller ones at my lfs.
