KH question

[azza]

Hi guys

With KH if it is too high can it cause damage to your discus fishs' health or not?

[azza]

oh yeh my kh is around 20 dkh or 358 ppm... not sure whether this is good or very bad

IMO better to have a lower KH reading. Too high and they may be un happy plus eggs are unable to hatch if there is a high KH reading.

I keep my kH at about 2 or 3 dkh. Just enough to provide some insurance against pH dropping suddenly.
