我加了1個fbf, 2星期內, no2巳跌回正常數值. 以下是我今次事件之疑問:
1) 在不改變environment之前, 加硝化菌似乎並不有效. 未加fbf之前, 每天落菌並不能減低no2(每次check no2都deep red, 嚇死人)
2) 未加fbf之前, 我有加bio ring in professional 3 (共有6L Bio Ring + 3 樽aqua charger, 號稱可process 幾千升水, 但我只有~250升水及2條總共2斤重之大魚), 但亦不能減低no2. 不知何故?
3) 當加了fbf及no2回落時, 我想, 如果fbf如此厲害(及省地方), 為何要用濾桶? 可否把濾桶撤掉而換成fbf? 又fbf有什麼壞處? 我在internet search 多個星期都找不到有關研究.
望有高人可告知因由, 什謝!

08 Jan: Check NO2, Deep Red,Change 30% Water, Add 硝化菌, 停止喂食
10 Jan: Check NO2, Deep Red,Change 30% Water, Add 硝化菌
12 Jan: Same as above
16 Jan: Same as above, 喂食4隻中蝦仁
17 Jan: Clean 濾桶, add bio ring + aqua chargers(及菌水)
18 Jan: Check NO2, Deep Red,Change 30% Water, Add 硝化菌
20 Jan: Same as above
22 Jan: Same as above
24 Jan: Same as above, 喂食2隻中蝦仁
27 Jan: Check NO2, Deep Red,Change 30% Water, Add 硝化菌
29 Jan: Same as above
31 Jan: Same as above
3 Feb: Same as above (very tired, 買鹽同菌都買窮), 喂食2隻中蝦仁
5 Feb: 把心一撗! Add FBF and Add 硝化菌, 唔掂就唔Q養la ...
9 Feb: Check NO2, Red, but color get lighter ...
Add 硝化菌
10 Feb: 喂食3隻中蝦仁
13 Feb: Check NO2, Light Red ... better ...
Add 硝化菌
16 Feb: Check NO2, OK!
注:
a) nh3/nh4 figures 是 zero, no3 deep red > 說明硝化作用是在運行中
b) add硝化菌=2xBioDigest + 10ml tropical science nitromax
c) FBF=O**O product + 1x 1000LPH submerge Pump (made in Italy)
