我量家中的自來水喉水NO3竟然是20ppm.
已用蒸溜水試過測試劑正常,你地的水喉水NO3是不是同我一樣呀.

我家中的自來水喉水NH3/4, No2, NO3 = 0ppm ---> Tester: Sera

PH =7.1, kh, gh = 0

可能我的水喉水NO3係20ppm
所以掂攪缸水都係20ppm降唔倒.
唔知其它區的網友有無相同的情況.

That's sounds like distilled water more... ARe you sure the kits are not expired? I never seen KH = 0 from any tap water before, in Hong Kong, they're mostly 2.5 - 4. f it is KH = 0 without any other buffer, your pH shouldn't be stable at 7.1, it would crash down with just very little CO2, even only from the air.

The test kit is not expired, it is very similiar to my mother's home, which is just the next mansion (5 mins by foot), and the PH is 7.

True, I also understand the tri-relationship of GH, KH, and PH. But this problem, doesn't really affect me anymore now. My CRS, I have to add some sort of stones to increase KH and GH to the rite level for CRS. And my dwarf tanks, they just love soft water! And everything is pretty much stable!

有,我家也是一樣,蝦缸的水比你還高,係100ppm住屯門村屋
打算用菲記濾水器,個個大大都話ok

嘩100ppm!咁夸張.會唔會食死人架!
我現在用OSIM過濾都唔得.我罧濾水器應該對NO3冇作用.

要買 RO 機才有用，濾水器無用。

現在我試50M 氣喉滴滴仔,盡量唔換水.
但形要每天加兩公升水,因吹飛扇.
希望可以降倒NO3.
