水草情迷

，除了減少燈光照明時間，我以前試過用AA除苔劑，我落了少少，便使我之前的缸草死了不少，有否好介紹，ADA or 其他牌子 ？

Those alage growing on the surface of the glass tank is not a big problem, just use an old credit card or a tooth brush to remove is ok.

Strongly not recommend you to use any kind of medicine, even it said it will not harm aqua plants to aquarium tank with plants, the effect won't last long and not good to the plants.
