The bottle is designed to make it possible to add 5 ml of Master grow at a time - enough for one week´s fertiliser in a 50-litre aquarium. However, Tropica asks aquarium-owners to fertilise only when necessary. If the new leaves of plants are dark the dosage can be reduced, and if they are light more fertiliser is needed. Aquarium-owners should also be aware of the hardness of their water. Soft water requires half the dosage of hard water. Dealers and private aquarium-owners alike can give their plants perfect growing conditions by looking after their aquariums correctly and observing Master grow´s instructions for use.
對呀 說明是說, 50升用 5ml, 但軟水再減半, 再依唔同植物種類, 狀態再調整.
佢既配方, 比歐洲大型缸, 大型草用應該好合適, 但陰性草吸收同生長都唔同, 要小心處理.
一次過落, 濃度突然增多, 水草吸唔晒, 你估又會益左邊個 !!
