4 jugs that are each 5L. No diluting necessary. This product replaces the 10L units which were popular but a bit heavy to handle. Can use them to simply top off your dosing containers and store the remaining liquid in the screw capped containers. CORE7 is a next generation of dosing solutions designed to supplement and maintain near natural sea water parameters for reef aquaria using the TRITON Method of reefkeeping. CORE7 improves on the original Base Elements range of supplements in several key ways. CORE7 is revolutionary because they are the most concentrated solutions ever developed, no other supplementation method in the world comes close in terms of value and stability. They do not need to be diluted, they can be used direct from the bottle saving space and eliminating the hassle / mess of preparation. CORE7 solutions have been re-formulated to be even more stable and include a raised pH to promote coral growth.Years of scientific research combined with observations drawn from tens of thousands of ICP aquarium seawater tests lead to the development of these unique elemental supplements. Used in accordance with the TRITON Method these solutions deliver the natural balance of macro and trace elements essential to a successful reef aquarium while preventing ionic imbalance and eliminating the need to carry out routine water changes. Note:Due to the highly concentrated nature of these products some crystallization/precipitation may occur during shipping. This is normal and product is still absolutely usable. Solution can be easily restored to full liquid by floating in hot water and stirring to dissolve the precipitate. To avoid precipitation please always store indoors as cold temperatures can result in minor crystallization.
