水草情迷

請問一般是否一個月清洗瀘水筒一次? 下列的方法是否正確:
1. 用舊水洗瀘棉;
2. 生物環可以不用洗;
3. 清洗後要補加dupla 硝化細菌;
4. 膠喉內附生著的黑毛藻使唔使洗走佢呢?
及問重生開動瀘水桶時魚缸會污濁一段時間, 口的魚及水草怕唔怕呢 ?

I just rinse the filter media with tank water, and didn't bother to make it too clean. I didn't add 硝化細菌, they are still on the filter media. (you can save the money for other stuffs, ie fertilizer, fish etc). No need to clean every month, cleaning is just needed when u feel the water movement has slowed down due to clogging.
Make sure u don't power off the 瀘水桶 for too long, or else the 硝化細菌 inside will die due to lack of oxygen(bec no water circulation).

ps. if 硝化細菌 already dead (ie power off too long), then need to clean the filter media properly, or else the dead 硝化細菌 will poison your water and your fish. After that, wait for the new colony to form, or add in bottled 硝化細菌 for faster result.

唔該, Alan 兄.
