Brightwell Aquatics Kalk+2 - Advanced Kalkwasser Supplement Information
Calcium, magnesium, and strontium are required for the formation of aragonite, the skeletal material of reef-building invertebrates such as corals, clams, tube worms, and their respective allies. Brightwell Aquatics Kalk+2 provides these elements and may also be used to help regulate pH in reef aquaria. Kalk+2 does not contain chloride salts, which is a strong point for some hobbyists. The use of kalkwasser-type products remains very popular with many seasoned hobbyists, regardless of innovations in calcium-delivery methods.
Instructions and Guidelines
Kalk+2 is intended for use by experienced hobbyists who are familiar with kalkwasser (calcium hydroxide-based) products. The calcium concentration (”[Ca2+]”) and pH in the aquarium should be determined by using an accurate test kit prior to supplementing. Do not add this product directly to an aquarium without diluting in water as directed, and do not overdose; it must be added in a controlled fashion with a dosing device. Create a stock solution by dissolving 6 grams (~1 tsp) of Kalk+2 in 1 US-gallon of fresh water (preferably purified) and allowing at least one hour for any settling to occur; each ml of the saturated sol’n will increase the [Ca2+] in 1 US-gallon (3.785 L) of water by 2.3 ppm, strontium concentration by 0.04 ppm, and magnesium concentration by 0.06 ppm. This solution must then be dosed/dripped into the aquarium at such a rate that salinity does not fall below 1.021 g/cm3 and pH does not increase by more than 0.1 every hour, nor is it ever allowed to exceed a value of 8.5. Dosing at night when pH in a reef aquarium is naturally depressed is often performed to avoid exceeding the maximum allowable pH value. If the [Ca2+] in an aquarium is gradually dropping despite using this product as directed, the rate of evaporation may be insufficient or pH may be too high to dose sufficient calcium to compensate for the rate of removal by reef-building aquarium inhabitants and/or undesirable chemical reactions. In this case, a secondary calcium supplement may be needed to occasionally re-establish the natural seawater concentration of calcium in the aquarium.
Caution: Calcium hydroxide is a caustic material; if inhaled, remove to fresh air, and in case of contact flush skin and/or eyes with fresh water for 15 minutes. Drink 16-oz. fruit juice if swallowed and seek immediate medical attention. Keep out of reach of children. Not for human consumption.

Dennerle CO2 Night Cut-off Valve Comfort
For magnificent plant growth, DENNERLE recommends a CO2 content in the aquarium of approx. 20 mg/l.
As certain correlations apply between CO2 content, carbonate hardness (CH) and pH value, the CO2 content in the water can be calculated according to a simple procedure:
Measure the carbonate hardness of your aquarium water.
Read the pH value which corresponds to the desired CO2 content from the table. You should set this pH value +/- 0.1 by adjusting the number of bubbles accordingly. Example: Carbonate hardness 4 °d, recommended pH 6.8 +/- 0.1.
The procedure is even simpler with the DENNERLE CO2 long-term test Correct + pH.
$18.00Dymax Base Soil series decreases the hardness of the water and lower the pH level to the degree at which most aquatic plants can consume nutrients and comfortably grow. The soil granules maintain the shape and density underwater security good circulation of water oxygen through the substrate. With Dymax Base Soil, growing difficult plants become easier and it is ideal for fishes demanding soft water.
