Reef•Basis Kalkwasser is a high quality calcium hydroxide, the original German limewater method of adding calcium, providing essential calcium for increased growth rates in corals, coraline algae, crustaceans and many other marine organisms. It contains no acetate, EDTA, gluconates, polygluconates or other unnecessary organics to pollute your aquarium.
Kalkwasser is primarily designed for maintenance and does not work rapidly, so you should first use our Reef•Basis Calcium if you have severely depleted calcium levels and need to raise them rapidly. Proper control of calcium level is imperative for the health and growth of corals and many other invertebrates. Continuum recommends that you maintain a calcium level of between 410 and 450 mg/L (ppm), an alkalinity level of 7 to 11 dKH (2.5 to 4 meq/L), and a magnesium level of 1250 to 1350 mg/L (ppm). Note: Aquarists keeping SPS corals should consider keeping alkalinity at 7 to no more than 9 dKH (2.5 to 3.21 meq/L).
This product is only meant for use by advanced hobbyists that are familiar with Kalkwasser. Never add powder directly to the aquarium! Dissolve 6 grams, about 2 teaspoons of product in 1 gallon of purified water to make a saturated solution. Stir vigorously, let stand for several hours. A white precipitate will form on the bottom of the container, and a crust may form on the top of the solution, this is normal. Decant the clear liquid into a dosing system and drip slowly over several days. Discard precipitate. Each gallon of Kalkwasser solution will raise the calcium level about 48 ppm in a 20 gallon (80 L) aquarium. Test the calcium level with a good quality test kit and adjust the addition rate as necessary to maintain the desired level.
Caution: Keep out of reach of children. Not for human consumption. Contains strongly alkaline calcium hydroxide, if ingested drink plenty of water or acidic fruit juice, consult your medical practitioner or a poison control center. If in eyes flush with water for 15 minutes, consult your medical practitioner. If on skin flush with water.
The Comline® DOC Skimmer 9004 DC is designed for use in seawater from 60 to 300 liters (15 to 79 Gal). It operates according to the TUNZE® flash skimming principle and acquires the water through an efficient surface suction with a surface film removal, and can therefore also be used as a "stand-alone" solution in the aquarium. The TUNZE® Foamer generates large volumes of fine air bubbles with a diameter of between .1 and .3 mm (.004 - .012 in.) and is especially quiet during operation.
The Comline® DOC Skimmer with a magnet holder for glass up to a thickness of 12 mm (1/2") is supplied installation-ready.
Air flow regulation and silencer
for an exceptionally quiet
Simple, quiet and effective - these are the current demands towards aquarium components. That is precisely what distinguishes the small Comline® DOC Skimmer 9001 DC - a true "plug and play" skimmer for small seawater aquariums with 20 to 146 liters (5.3 to 37 USgal.). There is no complicated setting or regular adjustment required for the operation. A simple installation into a corner of the aquarium is sufficient and it will work autonomously.
