B-Ionic calcoim and alkalinity buffer by ESV

Calcium and Alkalinity Buffer system

B-Ionic Calcium Buffer is the original, unique, easy to use,
two-component liquid supplement system. When using
equal volumes of each component, the aquarist can easily
maintain calcium and alkalinity levels with no mixing
powders, disruption of ionic balance, or addition of organic
chemicals. In addition to supplying highly concentrated
calcium and carbonate alkalinity required for calcification,
B-Ionic Calcium Buffer System also provides all other
important major, minor, and trace elements in the proper
ratios to duplicate the composition of synthetic seawater. As a result, B-Ionic Calcium Buffer System will help
restore inorganic ions lost from protein skimming and help
maintain the ionic balance of the aquarium water.

ESV Calcium Hydroxide kalkwasser
Calcium Hydroxide

Calcium Hydroxide is the proven standard for
maintaining calcium concentration and alkalinity in
closed marine aquaria. The calcium provided is
directly used by calcifying organisms, and the
hydroxide ions provided readily convert dissolved
CO2 into bicarbonate and carbonate ions, which
are also directly used by calcifying organisms.
The net result is no ionic imbalances in the aquarium
water, which can occur through the prolonged
use of other calcium supplements, such as calcium

ESV Strontium Chloride
Strontium Chloride

Our Strontium Chloride Solution is a very pure and concentrated
form of strontium, free of phosphates and nitrates. The aquarist
should be aware that Strontium Chloride does not add bicarbonate
and carbonate ions to the system. Since most calcifying organisms require these ions in addition to strontium ions, the
aquarist should monitor alkalinity frequently when using Strontium
Chloride and make the proper adjustments with a buffer

Exactly how strontium supplementation benefits marine aquaria is
a subject open for debate. Some have demonstrated its
effectiveness in precipitating orthophosphate from the water
column. This could result in less problem algae blooms and
enhanced calcification of corals and coralline algae by lowering
phosphates, which has been shown to "poison" calcification.
Others have speculated that less energy is required for calcifying
organisms to extract strontium carbonate than calcium carbonate
because of greater insolubility. Regardless of the mechanism
involved, there is strong anecdotal evidence that marine aquaria
dosed with Strontium Chloride show increased growth rates of
coralline algae and hard corals.

ESV Potassium Iodide Solution
Potassium Iodide Solution

ESV's Potassium Iodide Solution is a very pure
form of iodide. Iodide is an important micro-nutrient
for many marine plants. It has also been suggested
that iodide may play an important role in enhancing
a coral's ability to adapt to rapid changes in light
intensity and spectrum. Our recommended dosage
is 1 drop per gallon per week (1 ml per 20 gallons
per week).
