Dear Mr.
we are very sorry to hear that our product hw-Marinemix reefer has
given rise to cause of complaint.
As you were so friendly to give us your mailing address we have already arranged
the sending of 500 g KCl 99,9 % Ph. Eur., USP (in Ultra-pure Pharma quality).
We estimate that the parcel sending will arrive you within the next 14 days.
To adjust the potassium level in your aquarium water, we have allowed us
to include the following application guidance to elevate the potassium level.
The easiest and most comfortable way is an easy to prepare specified
Potassium chloride solution
This solution would be more easily and accurate to dose, than by trying
every time to weight out smallest quantities.
Preparing the solution:
Dissolve
190,6 g of the KCl 99,9% Ph. in
1000 mldistillated or R/O water.
The so prepared solution will contain then 100.000 mg potassium in dissolved
form.
If you dose 50 ml of the solution per 100-liter (26,42 US gallon) aquarium
water the potassium level will be elevated by 50 mg/liter.
Very important:
Please do not elevate the K-level not more than 25 mg/l per day!
Lowering the K-level can be done very quick and without any risk
of harm for corals and animals.
Increasing the K-level should be done slowly and in small concentration
steps to avoid excessive stress which could be very harmful to your aquarium
inhabitants.
Even if you know the actual K-level in your aquarium and you have calculated
how much of the K-solution should be add, please be extremely carefully to not
overdose!
A Potassium concentration below 100 mg/l will not cause any harm to your
animals and corals.
Exceeding the max. Potassium level of 420-430 mg/l involves a high risk of
mortality for corals and animals.
We beg your pardon for the caused inconvenience.
Since January 2017 a new analytic system has been implemented in the
quality control management. This reduces the possibility drastically that
a quality issues can underrun the monitoring system.
But even by this we must ask for your understanding that wherever human
beings are involved errors can occur.
With many tanks and kindest regards
