Alkalinity (Kh) along with Calcium (Ca) gets consumed by corals on a daily basis.  This consumption needs to be replaced.  Target range for Kh is 8-10 dkh.  Test often with a quality test kit.  It is important to keep Kh as stable (without big fluctuation) as possible.  This is why Kh is typically used along with Ca as part of a 2-part dosing system.  Kh and Ca can be dosed manually, if done in small amounts while monitoring your systems Ph level. MeCoral Kh is designed to raise Ph.   ME Kh is designed to be used along with ME Ca.

Quick guide: In order to raise Kh .10 dkh or from 8.00 to 8.10 in 100 gallons of aquarium water, add 5 ml.  Drip slowly and test as needed.

Mixing instructions:   MECoral Kh powder container is pre-measured to make a 4 gallon liquid solution.  In a 4 gallon container or jug, add approximately 3 gallons of your RODI water.  Add the entire MECoral Kh container of powder to the water in the jug.  Shake aggressively.  Add more RODI water to make a 4 gallon liquid solution.   Let rest before use. Do not pour the powder into the jug prior to the water, as this will produce clumping. If clumping occurs, place jug in a hot water bath and shake again.  A 5 gallon bucket filled to the handle line is 4 gallons of liquid.  If mixing 1 gallon at a time–use 15.5 ounces (16 oz is a lb); or aprox 1 7/8 cup.

Ingredients:  High Quality Pharmaceutical Grade Sodium Carbonate.

Caution:   Not for human consumption.  Keep away from children and pets.  If swallowed drink water, do not induce vomiting.  Call the doctor.
