A frequent occurrence in reef systems is low pH, while calcium and alkalinity are at optimal levels. Raise one and the others may fall. One of the primary reasons for this is an improper carbonate/bicarbonate ratio. The buffer ratio changes as a natural consequence of the buffer's ability to counteract acidifying sources such as organic acids (produced naturally from waste) or introduced from non-pH controlled husbandry products. In this case, adding more buffer would unnecessarily result in a rise in alkalinity and a drop in calcium. The first product of its kind, balance™ ends this see-saw effect. It resets this ratio by converting bicarbonate into carbonate in order to reassert a higher pH without affecting calcium level.

balance™ is an optimized blend of sodium and potassium hydroxides with a NSW ratio (27:1) of sodium to potassium to avoid ionic imbalance with long term use.

aquavitro offers other solutions designed to address the unique challenge of raising pH in a reef environment. ions™ addresses the problem of low magnesium which is a cause of low buffering pK and pH. eight.four™ addresses deficiencies in pK found in competing products by providing a properly balanced (carbonate/bicarbonate) buffer system.


balance™ is intended to be used to raise pH when all other parameters (alkalinity, calcium, magnesium) are at optimal levels, but pH is still low. The amount of balance™ needed to raise pH to the desired level will vary widely, depending upon the buffering capacity and quality of your tank water. For reference purposes only, one inner cap (7 ml) will raise 75 L (20 gallons*) of salt water by about 0.1 pH units.

Add balance™ in small increments, and check pH after at least 3 minutes before adding additional increments.

balance™ can be used daily and within minutes of calcification™, eight.four™, and ions™

Note: The aquavitro cap offers multiple dosing solutions depending on the size of your system. Each inner cap thread is approximately 2 mL. The inner cap contains 7 mL, while the outer ring contains 28 mL (35 mL when both are filled to the level of the inner cap.) When filled to the top, the cap contains 49 mL.

Use Seachem's MultiTest™: Marine pH & Alkalinity kit to check pH.
