The measures three most basic parameters for the
water management of Koi pond.
Salinity –
Maintaining correct level of salt in pond water benefits fishes
especially koi, here are the benefits:
It is safe for pond fish species
It does not push sick fish “over the edge.”
It eliminates 7 of 9 parasites commonly found in the pond
It reduces the effects of nitrite toxicity
It stimulates mucous slime coat production
It does not get bound out of the system by organics or sunlight
Yet prolong higher salt level can form salt resistant parasite. Critical
salt balance is the key to a healthy pond.
The setup of hospital tanks at the right salt level is also made easy
with this meter.
pH –
Higher pH indicates a more alkaline water while lower pH is more
acidic. Maintaining pH at around pH7.5 will be most ideal for Koi as
in their native environment. pH value is also a good indicator on
CO

accumulation as CO

increases pH will be lowered.
Any sudden pH fluctuation can result in fish leaping off the pond.
Always adjust pH gradually over a period of time.
Temperature –
Though Koi can survive between 1 to 30°C (35 to 90°F), at higher
temperature, Koi will increase respiration and speed up aging and
thus produces more waste. Extreme temperature reduces oxygen
holding capacity in water and causes koi to gasps for breath or
worst, leap to its death.
The ideal temperature for koi is around 20°C (70°F). In winter, do
not feed koi when temperature falls below 11°C (52°F) as koi
cannot digest and soft diet when below15°C (60°F)
