Reef-building corals extract calcium and alkalinity from the aquarium water when building new skeleton and tissue.  If you’re keeping corals in an aquarium, you will need periodically supplement the water to replenish these essential elements for the corals. When adding separate liquids or powder additives, the ratio of calcium to alkalinity can quickly become unbalanced which leads to poor water chemistry and ultimately inhibit the corals ability to grow in your tank.

Maintaining the proper ratio of calcium to alkalinity is considered one of the most important water chemistry parameters to “get right” when keeping a reef tank. The ESV B-ionic two-part calcium and buffer system is an easy way for you to maintain the perfect balance in your aquarium.  The ESV two-part liquid product is formulated to provide the same ratio of calcium and alkalinity used in coral calcification. This reduces the chances of under or over-dosing these important elements. The ESV 2-Part system will eliminate the rapid rise and fall of calcium and alkalinity that occurs when dosing unbalanced additives.

Using the ESV 2-Part system is easy. Just dose your aquarium with equal amounts of each bottle based on your tank's demand for calcium and alkalinity.  To get started, you want to ensure your calcium and alkalinity levels are balanced and at the proper level in your tank. You then start with the minimum daily dosage for your tank size and test daily for the first 3-5 days. You can then increase or decrease the daily dosage based on your water tests.  ESV B-ionic is one of the most widely used two-part buffering systems because it is affordable, easy to use, and has proven time and time again to produce great results in reef aquariums.
