水草情迷

"In the context of fish liking hard vs. soft water, we speak of GH. However, in discussing CO2, we will be dealing with KH. "

This sentence is capture from http://www.thekrib.com/Plants/CO2/

Is that means the value of KH will not affect fish to much?

當然不是啦, 不過多數養在水草缸內的魚, 和水草需要的水質很相近, 而且在相對上來說, kh 高時, ph 都會高, 相反亦然. 所以才沒有特別注意.

如果要養湖魚慈鯛, kh 是要較高的, ph 亦要弱鹼, 太低就養得不好了.
