下墜球式測試器

是通過液體的顏色確認魚缸中CO ₂濃度的玻璃器具。在測試器中放入試劑和魚缸水，只要安裝在魚缸中，根據CO2添加量和水草的光合作用量，液體的顏色變化為藍·綠·黃。作為CO ₂添加量的基準最適合。

※附帶pH試劑5ml 一支
※魚缸的pH值很低，最初時變為黃色的情況下，即使添加CO2，液體顏色也不再變化。此情況下，請進行魚缸換水，提高pH值，液體顏色變為綠之後請安裝到魚缸。

Drop Checker

A glass-made instrument created specifically for examining the CO₂ level of aquarium with simple procedure. Add some pH reagent and aquarium water to Drop Checker. Then, set it inside the tank .

* Includes a pH reagent (5ml)
* In case the reagent turns yellow from the beginning, due to the low pH value in the aquarium, the reagent color does not change even after adding further CO₂. In such a case, please make a water change for raising pH level, and make sure the reagent turns blue or green before resetting Drop Checker in the aquarium.
