The Continuum advantage.
Reef•Basis Potassium is a high purity potassium in dry form, which is particularly useful in aquaria housing SPS corals. Potassium plays a vital role in the formation of aragonite, as well as the coloration of many corals. It will replace potassium lost to zeolite and resin filtration, contains no acetate, EDTA, or polygluconates and is much stonger than many competitor’s products because it is made from anhydrous salts, not hydrated salts.
 
Use in aquarium keeping.
Proper control of mineral levels 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), a magnesium level of 1250 to 1350 mg/L (ppm), and a potassium level of 380 to 405 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).
 
Directions and protocol.
Dissolve 1-1/4 grams, about 1/2 teaspoon of product in 8 oz. ( 236 ml ) purified water. Add in an area of high flow directly to tank for each 25 gallons ( 100 L ) capacity, every other day until the desired potassium level is reached. For best results, measure the potassium concentration and add as necessary to maintain between 380 and 405 mg/L (ppm).
 
Expert use.
To dose, determine the amount of potassium consumption during the time it takes add the entire volume of your drip system. Determine the amount of Reef•Basis Potassium to add to your drip system in grams by multiplying your tank capacity in gallons by the amount you want to raise it in mg/l (ppm) and by 0.008.
 
(Example: if you have a 25 gallon tank and you want to raise the level by 25 mg/l (ppm) with the entire dose, you would multiply 25 x .008 x 25, which equals 5 grams or about 2 teaspoons of Reef•Basis Potassium.)
