Thrive 2 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.
When purchasing more Thrive 2 Calcium, you can refill your bottle with the Thrive 2 Calcium Refill 20.3 oz.
Directions for Use:
Determine the calcium in the aquarium before supplementing. For best results, obtain a customized Thrive Prescription at your local fish store or at www.ThriveAquatics.com based on your current tested parameters. 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.
