Can be used with calcium, but also carbonate buffer and essential trace elements such as strontium (up to 10,000 ppm). Mixed Grade. Grain size: 2.0 -5.5mm. Lightly rinse before use.
Determining how much substrate to buy for your new aquarium depends on the size and shape of your tank, as well as the depth of the substrate bed you wish to achieve. Another factor is the type of aquascaping structure you're planning.
Refugiums, small aquariums that either sit next to or hang onto an existing saltwater or reef aquarium, are used by a growing number of aquarists to continually cycle water into and out of the existing tank.
