| water parameters needed?
I have tested: Ph, Kh, Gh, Amonia, Nitrite, Nitrate and these are at acceptable level.
Is there another water parameters needed to make our koi healthy such as phospate, fe,etc?
I ask this because I use ground water which may contain dangerous material for koi.
and I think my water contain phospate since the waterfall stone have white spot when it is dry.is it dangerous?
thanks for your sharing
