其實可謂水質？好與壞又如何介定？大家齊來制定 ' 好水質 ' 之標準吧8D8D8D
我只知少少，作開場白吧:)
- salinity: 1.024 - 1.026
- NH3/NH4 - 0
- NO2 - 0
- NO3 - 0
- ph - 8.4
- kh - ??
- 含氧量 - ??
- 水溫 - 24-26C
- trace element 含量呢？
- bio load 定義呢？

好水質的salinity要1.024~1.026嗎？這個真的不知道啊！My tank's salinity is always in 1.019~1.020。

哈哈，又一次証明我的記憶力衰退xx(xx(
查返本乜乜altas乜乜, 幾乎全咸水魚介乎 1.015-1.030，但以 1.020-1.022 的種類最多。for FOT 就咁定得嗎？？

actually except N-cycle products, KH, pH, temp, salinity and dissolved oxygen all varies with seasonal changes....so everything has a range of tolerance, e.g. hyposalinity for fish
actually, fish/coral come from different region will has a different requirement, but they all can tolerate a slight deviation.....so all u need to do is to keep the system stable, not to fluctuate a lot so that the organisms can have time to adapt to it
for bio-load, actually your tank is doign very good, because u never see fish being soooo crowded in the sea...haha....so just keep less and feed less:D

For a FOT:
salinity = 1.020-1.024
pH = 8.0-8.3
KH = 7-10
temp = 24C-30C

If your NH3 and NO2 isn't zero, your fish is in danger.
If NO3 is higher than 50, bioload is high.
