Ok did the test ammonia 0 nitrites0 nitrates0 ph 7. Hardness 150 kh 40. My water doenot have much of a buffering capacity. I may have to recycle the tank now but at least I know my axies are safe and will test again tomorrow.

Half a teaspoon of bi-Carb soda (baking soda) per 100 litres of water will increase the Kh by 1 degree of hardness. It must be done slowly as it can directly affect the Ph logarithmic scale.
