水草情迷

請問 KH 太底會唔會死魚? 我的缸一向在KH0-1 左右. 換水時會加黑水入水喉水去調和, 不知是否因此原因燈魚, 鯛魚都無緣無故死去.

現在嘗試不下黑水, 直接用ph 8 的水喉水, 反而沒有死魚了....

If KH too low (0, unmeasurable), small increase in H+, ie, add acid, co2, will cause large swing in pH. KH increases the buffering capacity of ur water. So recommended KH is 2~4 (soft water). Some fish is sensitive to large pH swing. Some fish can't tolerate kH too low (i think guppy doesn't like low kH).

If kH too low, just add baking soda to the water.
