I have finally made progress and all my readings are near good (Ammonia still at .5, NO2=0, NO3=0, PH=6.6), but I'm a walking bucket brigade at this point so the ammonia will be gone by tomrrow. My question is, my water is extremely soft and alkalinity is zero. Are these actual problems if the fish are thriving and if so, how can I safely increase them without stressing the fish?
