水草情迷

請各師兄指教, 用甚麼方法是最便宜準確簡單去測試KH和PH, 我的缸是草魚混養, KH和PH的度數應是多少, 我在魚街見到一些玻璃容器內, 有紅色液體放在魚缸內, 是否用來測試PH
另外甚麼是KH呢, 真是一頭霧水?

What kind of fish do you have? Generally speaking, plants require lower pH, i.e. 6.0-6.5. But some kind of fishes require higher pH, e.g. guppies. You can't keep them in the same tank. Some fishes like tetras, they can survivie in lower pH as plants. That is why you can see why most of planted tanks have tetras. Checking of pH is not rocket science. You can use test tubes, or even pH paper. Both are fine. I suspect that the one you mentioned is for checking CO2 level. They should of green or blue, not red. You'd better post a photo here to confirm.
