水草情迷

小弟開缸都有2個多月, 用Hydor P10濾桶,
但係睇過好多有關過濾系統文章之後,
發覺Hydor P10濾桶的濾材排列順序好似有d問題,
唔知有冇ching係用Hydor濾桶呢?

我新買返來時, 老闆話濾材排列應該係咁嘅(由下至上)
黑色生化綿 --> 生物環 --> 白綿
我一開始到現在都係咁放, 出水好順
但係Hydor P10濾桶, 水流係由下而上,
啫係水係先流過 黑色生化綿 --> 生物環 --> 白綿
咁咪唔啱囉

我又試吓張濾材相反咁放(由下至上)
白綿 --> 生物環 --> 黑色生化綿
個水流好慢, 個馬達好嘈, 怕整壞個濾桶

問題:
有冇ching係用Hydor P10濾桶, 可唔可以講吓你點放濾材呢?

就同Hydor網站所講既:

In what order should the filtering materials be inserted into my Prime filter?

There are different schools of thought on this issue. From the point of view of biological filtering efficiency, it makes little difference how the materials are positioned. All we can do is offer some advice on how to position the materials, starting from the bottom. For sparsely populated aquariums: large-pore sponge, cylinders, carbon/zeolite, fine filtering poly wool pads. For densely populated aquariums: cylinders, large-pore sponge, carbon/zeolite, fine filtering poly wool pads. The second option is better for decanting the particulate matter of the aquarium.

濾材排列對過濾效果既影響好細
亦都冇一個所謂正確既排法

濾材既阻力應該係一個整體咁計
1+2+3 或者 3+2+1
總阻力都係一樣
你將濾材排法改左之後變得水流慢馬達嘈
應該同排列順序無關
係有其他原因

多謝ching回覆,
之前我都有睇過官方說法,
但都有人講, 如果排法唔同, 就會影響水質
e.g. 唔先用白綿filter out 魚屎, 魚屎會落到生物環,
雖然生物環係消化菌生長, 照理論應該唔大影響, 因為消化菌會張魚屎化解,
但係魚屎一日多過一日, 消化菌會吃不消, 結果水質會變差 (如有錯, 請指出)

所以我先會問大家, any idea ?
