Thrive Calcium is designed to increase calcium levels in your salt water reef aquarium. Most reef aquariums will need supplementation of calcium for inhabitants like coral to grow and to multiply.

High Concentrations:

Thrive Calcium is a saturated solution of calcium chloride. Thrive Calcium is the most concentrated and efficient Calcium product on the market. 


Determine the calcium in the aquarium before supplementing. For best results use a high quality calcium test fit from Salifert or do a complete lab water test using the Triton Labs Method.  DO NOT OVERDOSE: Your salt water reef aquarium is a delicately balanced system. Calcium greater than 500 ppm may damage equipment and increase the loss of alkalinity, magnesium, and strontium. Do not directly mix with any alkalinity, magnesium, or strontium supplement. Do not raise calcium more than 50 ppm per day.
If not using a Thrive Prescription: Add 1 ml per 5 gallons daily until the desired calcium is obtained. Then dose daily as needed to maintain calcium at 380 to 450 ppm. Dosing without a Thrive Analytics prescription is not recommended. Advanced directions: Each ml of calcium will increase the calcium in 1 gallon of water by 52 ppm. Add Calcium at a maximum rate of 1 ml per 2 gallons daily until your target calcium is reached. Then dose daily or weekly as needed. Daily dosing may increase coral growth.
