水草情迷

請問 ching
(一)新開缸濾桶內除生化棉,生物環外,是否要放活性碳?活性碳是否在一段短時間內要拿起? Active carbon is not a must unless you find the water yellowish. You have to replace the active carbon once every month or they will release toxic materials.
(二)新開缸水黃,爬文知道可以換水,請問換水時是否關上濾桶? You don't need to turn off the canister everytime you change the water.次數多會否影響濾桶的耐用能力? What do you mean by "次數"? "次數" of changing water? Or, "次數" of turning off the canister? The answers for both questions are "No, it won't.
(三)如果不用關上濾桶,雨林管是否要移到缸中較底位置,但會對後排較高的水草有所沖擊(魚缸只高14")? If that's the case, you may turn off the canister when you change the water.
請指教
謝謝
