Prima Line 05 Combi Calcium 500ml

Prima Combi-ca is an innovative additive formulated using highly bio-available organic calcium, designed for a DOUBLE EFFECT:

  • to MAINTAIN the correct level of calcium
  • to IMPROVE the medium term stability of this element inside the tank.

  • Based on an organic complex of Calcium it has a higher bioavailability than an ionic formula thus improving its assimilation by the corals and providing a rich source of metabolic energy to help maintain peak corals conditions. Prima Combi-ca may be used in combination with Prima Alkali to maintain calcium at the proper level and is not intended to increase the calcium level but to improve its assimilation by the corals. If calcium becomes seriously depleted one should either perform a water change or use an ionic calcium supplement, such as ELOS Expert Calcium, to restore to the natural level as in NSW.

    Part of our Prima Line Integrators, Prima Combi-ca is designed to be simple to use but also very precise to dose. On each bottle it is clearly stated the increase of Calcium obtained with each measure thus permitting the user to create their own integration program without the need of complicated calculations. As per our more specific Expert Line, even these integrators are subject to our strict production processes, to supply the aquarium lover the safest and pure quality additive without the need of preservatives. Prima Line Integrators: ELOS QUALITY at an affordable price.
