Marine calcium supplement great for hard and soft coralsEasy-to-use concentrated liquid calcium formulaCalcium helps maintain a high pH needed in marine aquariumsProvides necessary calcium to enhance the growth of hard corals, soft corals, and other reef invertebrates. Great for tube worms, snails, and clams, as well as purple, pink, and green encrusting calcareous algae (coralline algae). With regular use, corals open more often and stay attached to their skeletons better. Calcium is vital for the health and growth of corals and also plays a crucial role maintaining high pH needed in marine systems. Phosphate and nitrate free. Does not raise DOC levels. 16 oz treats 6,000 gallons. For best results, use Kent Kalkwasser Mix first.Contains no EDTA, gluconates, lactates, or other sugars, which increase bioload and may accumlate over time and spur unwanted slime or bacterial growths and/or sequester trace elements.Remember that establishing and maintaining proper water chemistry over the long term are the most important facets of marine aquarium husbandry. Accurate test kits are crucial to help you monitor and maintain water chemistry.Please click on "More Information" for ingredients and directions for use.

Easy and convenient calcium supplementation system for reef aquariums Raises calcium, magnesium, strontium, and alkalinity to promote coral growth Produces the same results as calcium reactors without the high cost and maintenance Easy-to-use complete calcium and buffer system offers the same results as costly calcium reactor systems. Convenient one bottle calcium supplementation system raises the concentration of calcium, magnesium, strontium, and carbonates (alkalinity) in your reef system to promote healthy coral growth. Eliminates the need to invest in expensive calcium reactor, media, CO2 tank, etc. Ionically balanced formula contains no chloride, phosphate, nitrate, or gluconate. Poses no risk of causing problems with algae and/or pH balance. Please click on "More Information" for directions, active ingredients, and general information.

Lugol's Solution is a bio-available iodine supplement for reef-type marine aquariums. Provides a strong source of reef iodine and iodide to reef inhabitants and macroalgae. Helps improve coloration of corals while preventing bleaching. Particularly well suited for aquaria containing xenia and soft corals. Enhances coral polyp expansion, resulting in a healthier environment for marine invertebrates and fish Can be used as a dip for stony and soft or leather corals. 1 oz. 1 drop treats 25 gallons.

Marine buffer safely raises and maintains a pH of 8.3Will not raise pH above 8.3 even if inadvertently overdosedMaintains both pH and alkalinity (KH) without disrupting the natural ionic balance of marine waterEasy-to-use marine buffer safely raises and maintains a pH of 8.3. Contains a natural balance of sodium, magnesium, calcium, and potassium salts of carbonate, bicarbonate, and borate to enhance and maintain buffer capacity at pH 8.3 without sacrificing calcium. Special blended formula maintains both pH and alkalinity (KH) without disrupting the natural ionic balance of marine water even with prolonged use. Dissolves rapidly and does not obscure water clarity. Ideal for marine, brackish or alkaline freshwater aquariums. 250 grams treats up to 1,000 gallons.Please click on "More Information" for usage instructions.
