許多魚友，很容易犯了飼養上高密度的大忌，若你的過濾器功效不夠強大，許多麻煩問題會接二連三而三，魚也不會健康。
這次的過濾器改造上部過濾器型式的四尺魚缸，因飼養魚隻尺寸較大、數量較多，平日產生的排泄物量、飼料殘餌及有機雜質污染也會較多。該魚友共放置12（3x4）個過濾盒，在調整改造前先進行2次清洗海棉，觀察平日過濾器被污染程度。經過2次清洗，第一層3組濾盒中的海棉表面都是厚厚的一層污垢，雖然經過清洗後，去除些許污垢，但3天後，棉體表面又出現一層厚厚的污垢。
Reconstruction Filter 1, It will be executed a filter of 4 feet aquarium tank alteration, we will observe the effect of difference transformation before and after.
Stage 1：
There are A1 ＆ A2 experiment in stage 1, it will observe the sponge surface contamination. After A1 (3 days to A2), the sponge have lot of dirt on surface.

在調整更新前，先進行A階段實驗觀察，該階段又進行A1與A2，期間進行1次清洗海棉，觀察第一層海棉表面受污染程度。在A2實驗測試結束，進行水質測量，測量結果分別為：
There are A1 and A2 before adjusting update, it will observe dirt on sponge surface and water quality measurement after A2.
二、準備改造 Ready to change new
（一）、海棉表面污垢 The dirt on sponge surface
濾盒1 Filter Box 1
濾盒2 Filter Box 2
濾盒3 Filter Box 3
（二）、改造前測量水質反應:： Measure water quality response before change new
由於該魚友目前已安裝流沙過濾器、氨氮處理機、一組桶型外部過濾器，及放入許多木碳，是相當「龐大設備」飼養，特別在降低氨氣值、培菌設備的「加強」，因此，pH值、NH3、NO3等三項數據「相當漂亮！」，但這樣「高投資」、「龐大設備」飼養方式，並非是一般魚友所能承擔的。
三、調整更新 Update ＆ adjustment
（一）、改造更新後 After update ＆ adjustment

第一層 The 1st layer
第三、四層 The 3rd and 4th layer.
（二）、安裝後1小時測量水質反應： Measure water reaction after 1 hour
NO3值：0
（三）、調整改造預期效果： Expected result
這次調整改造的重點，在於： Transformation priorities, including:
1.提高海棉層阻擋污垢效果，減少清洗及更新海棉次數，降低益菌大量流失 Improve the effect of sponge barrier dirt, reduce cleaning and updating sponge, reduce huge loss of beneficial bacteria
2.減輕降低魚缸重量壓 Reduce the weight pressure of tank
3.減緩水質敗壞速度，提高魚隻穩定度 Alleviate the speed of water corruption, improve the stability of fish
四、安裝後檢測工作 Inspection work after finish to change new
（一）、檢測點1 Inspection work 1：觀察第三層羊毛絨表面污染情況 Observed the third layer soft sponge surface contamination
（二）、檢測點2 Inspection work 2：水質測量反應： Measure water quality response
1.完成安裝時的水質反應。 Measure water quality after change finished.
改造後一星期，進行多項檢測，包括：
（一）、過濾棉阻擋污垢效能 The obstruct dirt effectiveness of filter sponge
由於飼養魚隻數量較多、魚隻尺寸較大，產生的排泄物、飼料殘餌、有機雜質量較多，更新《mini 多效除垢培菌棉》組後，能否提高物理過濾層阻擋污垢效能？減少水中細微污垢？減緩水質敗壞速度呢？
在進行改造時，因同時檢查魚隻狀況，不慎造成雄魚噴出精液，隔天立即進行換水工作，避免水質敗壞繼續擴大。餵食方面，則按照平日餵養量與次數，觀察一星期各層海棉表面污垢累積及水質清澈度。
第一層過濾棉由上而下，依次為：高效擋污過濾棉（Mini high efficient cleaning filter sponge）→長效培菌擋污棉（Mini high efficient bacteria culture filter sponge）→長效多層培菌棉（Mini multi-level bacteria culture filter sponge）。
第三層濾盒則為羊毛絨（Soft sponge），檢測羊毛絨表面受到污染情況。
1.第一組濾盒 The 1st column filter box
第二片海棉 The 2nd piece of sponge：長效培菌擋污棉（Mini high efficient bacteria culture filter sponge）
2.第二組濾盒 The 2nd column filter box
（二）、第一週水質測量 The first week water quality measurement
在水質部份，在改裝安裝後一星期期間，魚友放入許多河蚌，入缸後1～2天後，河蚌突然死亡一半，造成水質瞬間敗壞，水面出現較多細小泡泡、TDS值爆量（超過TDS最高值2,999），在測量NO3值，測得結果介於60.0～80.0，這是一個非常危險數據，經與魚友討論後，先停止繼續測量工作，先將剩餘的河蚌移出魚缸，避免河蚌繼續死亡而污染水質，並立即進行換水，待下星期再進行測量水質。
I n this week, this fish friend input some mussel, but the mussel have died after input aquarium tank 1-2 days, water quality corrupt very quick, there are some bubbles on water surface, the T.D.S. value over 2,999, NO3 value 60.0-80.0, this is a very dangerous digital, It will stop to measurement work after study with this fish friend, he removes all mussel to void water quality to deteriorate continuously, we will test and check all work again next week.
NH3值：沒攜帶測量藥劑，沒有進行測量！ NH3, Not carry measurement agent, No measure!
由於該組過濾器水平線出現左低右高歪斜，導致大多污垢都集中在最左側（第一組）濾盒棉體表面污垢特別多，但棉體表面污垢則是平均分散，並沒有集中在注水處沒有下方或局部。另外，觀察受污染痕跡，第一層過濾棉（多效除垢培菌棉）幾發揮了相當大的阻擋污垢效果。
Because e those filter boxes appears right low and left high skew, most of dirt are concentrated to far left filter box (first column), the sponge surface dirt particularly, sponge surface dirt is evenly distributed and not concentrated at the injection or topical to 1st layer sponge, Observation the traces of contamination is quite large, the first layer filter sponge（mini high efficient cleaning filter sponge) can play an high-performance to obstruct more dirt.
第二層的三片「長效培菌擋污棉」（high efficient bacteria culture filter sponge），也發揮培菌及阻擋污垢功效，在棉體表面有許多細微的污垢，且海棉吸水相當飽和，這相當有利於海棉培養益菌功效。
There are 3 piece of high efficient bacteria culture filter sponge at 2nd layer, the filter sponge play high-performance to obstruct more dirt and to cultivate abundant bacteria, this filter sponge strong water absorption, This is very beneficial condition for beneficial bacteria survive and multiply by sponge.
經過一星期後的第三層「長效多層培菌棉」（multi-level bacteria culture filter sponge）表面仍相當乾淨。這種類似白棉材質的過濾棉都放置在第一層用來阻擋污垢，因為棉體間孔隙較大，很容易堵塞較大尺寸污垢，導入水無法順暢穿透，使用一段時間後，大多魚友都丟棄換新，丟棄海棉也讓大量的益菌群瞬間消失。「長效多層培菌棉」讓白棉材質的過濾棉，完全做培菌功能，加上整片棉會浸泡在水中，大幅提高培菌效果及減少污垢堵塞孔隙。
The 3rd layer sponge （multi-level bacteria culture filter sponge）surface is very clean after 1 week, Its characteristics are very similar with general filter sponge, almost all white filter sponge, the main purpose is to obstruct dirt, white filter sponge in use for period of time, pore will be blocked by dirt, water can not pass through filter sponge pores, dirty filter sponge will be discarded by most of fish friends, Beneficial bacteria in filter sponge will be disappear.
The soft filter sponge in 3rd layer filter box, It has no be cleaned for 1 week, the surface is very clean, only slim black dirt spots on filter sponge surface, mini multi-effect cleaning and bacteria culture filter sponge provide powerful effect to obstruct lot of dirt. water penetration is quite smooth in throughout filtration system.
清洗後的海棉 After cleaning sponge
第一層的高效擋污過濾棉（high efficient cleaning filter sponge）「成功攔截」不少污垢，表面累積許多污垢，這些污垢是否會堵塞海棉孔隙呢？可以清洗乾淨嗎？答案是：可以的！只要簡單2個步驟即可快速又輕鬆除去表面污垢，讓海棉表面乾淨如新！
The 1st layer filter sponge can obstruct lot of dirt easily, but how to clean those dirt on surface? clean? or discard? mini high efficient cleaning filter sponge can clean it easily and quickly, it will very clean same as new. The answer is, Yes, of course! it is very easy and quick to clean by 2 steps.
