Independent studies show that some trace elements accumulate in home aquariums to potentially toxic levels. SeaElements avoids contributing to this problem by including only those elements that are typically depleted from aquarium water - in the proper concentrations and ratios. Other supplements promote a long list of elements in an attempt to offer something 'more'. We offer the only formula that contains just what your aquarium needs.
250ml (8.4 fl oz) bottle

For aquariums with dense growth of reef building corals, this supplement provides an extra boost of strontium that enhances the deposition of calcareous skeletons. Does not contain molybdenum. 250ml (8.4 fl oz) bottle.

Iodide and iodine supplement made from potassium iodide and seaweed extracts. Use this supplement to provide an extra boost of this important element and observe the positive effects. Great for growing Xenia, other soft corals and delicate red and brown seaweeds. 250ml (8.4 fl oz) bottle.

Two Little Fishies Calcium Concentrate makes it easy to rapidly adjust the calcium level in an aquarium. The long-term maintenance of calcium levels is best managed with a balanced ion supplement such as Kalkwasser or Two Little Fishies C-Balance®, which maintain alkalinity in addition to calcium concentration. Use Two Little Fishies Calcium Concentrate to raise the calcium concentration when the alkalinity level is already high. In this case, Calcium Concentrate will simultaneously raise the calcium concentration and lower the alkalinity level, bringing both closer to a natural seawater ratio. When the calcium and alkalinity levels are properly balanced, stop using Calcium Concentrate, and continue using a balanced supplement such as C-Balance, which provides carbonates and bicarbonates, calcium, magnesium and strontium in the correct ratios.
500 ml (16.8 fl oz) bottle

Two Little Fishies Magnesium Concentrate is a solution that contains the element magnesium, an essential pH-stabilizing component of the seawater buffering system. Magnesium is also important for the operation of various cellular enzymes, and is a key component of the pigment chlorophyll and the functioning of photosynthesis in plants. Two Little Fishies Magnesium Concentrate replenishes the magnesium concentration with a seawater ratio of magnesium chloride and magnesium sulfate. It helps maintain optimum water quality for corals, coralline algae, macroalgae, seagrasses, and mangroves. 500 ml (16.8 fl oz) bottle

Two Little Fishies Iron Concentrate is a solution that contains the elements iron and manganese, which are essential to the health of all plants, including the symbiotic zooxanthellae in corals and sea anemones, and sea-grasses.
