Brightwell Aquatics supplements and salt are the best. 3 tablespoons of Kalk+2 in my KW 300 Reactor every few days keeps my calcium levels at 400ppm and my magnesium at 1400ppm. Using Red Sea Reef Foundation pro test kit.

Rated 5 out of 5 by JimG A nice Kalk mix
I've been using this kalkwasser mixture for a few weeks now with positive results. I chose to dose kalkwasser mainly to combat the higher CO2 levels we have indoors here in the northern climates during the winter months. CO2 is largely responsable for lowering pH and during the winter months my pH usually runs about .3-.4 lower than when I am able to keep the windows open during the warmer months. Part of the kalkwasser combines with the CO2 in the water to form bicarbonate so it raises pH and acts as a temporary buffer as well. As well as acting as a buffer, kalkwasser helps to add calcium to the water. This particular kalkwasser mix has the added benefit of having the correct ratios of magnesium and strontium which helps to keep things ionically balanced as well. You should always keep a close watch on pH when using this product and a pH monitor works well in this regard. Also kalkwasser should always be dosed in a controlled manner due to its high pH.
