Right now I am using a 潛水式濾水器 + a 小型外掛式過濾器 with the 活性碳 inside. However, the water is not very clean and clear even I change 1/3 of water everyweek. (My tank is 18”)
When I search the old posts here, I found that most of you would not suggest using 活性碳 to make the water clear.
想問問:
1) 生物環是否可以有效地 make the water clear?
2) For the usage, is it just put the 生物環 inside the 外掛式過濾器 and take out the 活性碳?
3) Do the 生物環 need to be taken out to clean regularly? If yes, how and how often?
4) Which type (or brand) of 生物環 will you suggest to use on the 小型外掛式過濾器 and around how much?
Since I am a very 新手 on 養,魚, please forgive my so many dummy questions.
