于 2004-04-12 22:18 Thanks 岩礁園丁 Great! There is no noise at the down flow pipe. However, I think I need to buy and DIY all requested parts before I decide to use 同軸上落 and order the new tank..
Thanks 海洋管理員 Unfortunately, I live in HK and cannot go there to buy this part. I will go to 利可保 to check this part.
