Our Complete Tank System is a simple and effective all-in-one solution designed to support vibrant coral growth, strong skeletal development, and overall tank health.
Part 1 of our Complete Tank System is packed with bioavailable Calcium and Magnesium, to help maintain ideal water chemistry for stony corals and other calcium-dependent organisms. A precise blend of essential Trace Minerals mimics natural seawater conditions, replenishing what gets depleted over time. And finally, we’ve added Amino Acids to fuel coral growth and metabolic activity.
Perfect for reef keepers who want maximum results with minimal dosing complexity.
Can be used as a standalone part 1 to be combined with other alkalinity products.
IDEAL CALCIUM & MAGNESIUM LEVELS
Recommended calcium and magnesium levels to maintain a healthy reef aquarium are:
Calcium: Between 430–450 parts per million (ppm).
Magnesium: Between 1200-1400 parts per million (ppm).
This product is intended to maintain magnesium levels when used with both parts of the Complete Tank System. For tank magnesium levels below 1200 ppm, it is recommended to use a separate magnesium product to bring levels within the ideal range. If calcium is low, and magnesium is at or above the suggested ideal range, this product can still be used.
STARTING INSTRUCTIONS
1. Measure Calcium and Magnesium Levels in tank, and use the chart below to determine how to proceed:
| Type |
Level Threshold |
Action |
| Calcium |
Below 430 ppm |
Continue with instructions below. |
Within ideal range
(430-450 ppm) |
Determine if calcium needs to be maintained or increased and continue with instructions below as needed. |
| Magnesium |
Below 1200 ppm |
Use a magnesium supplement to raise levels to ideal range |
Ideal range or higher
(1200-1400 ppm+) |
Continue with instructions below. |
2. Shake the product well before using.
3. Dose: The recommended amount to add is 5ml per 10 US gallons daily until your desired calcium level is reached (see range above). Add the product at a maximum rate of 5 ml per 10 US gallons daily until your desired calcium level is reached.
4. Maintain: Dose daily or weekly as needed, see maintenance instructions below.
MAINTENANCE INSTRUCTIONS:
Each aquarium has unique calcium and carbonate requirements (which primarily affect alkalinity and buffering capacity, hence pH stability). It is common for different amounts of calcium and alkalinity to be needed to maintain the correct calcium and alkalinity levels. To determine the daily dosing rate for your calcium maintenance, divide your daily calcium decrease by 10 and multiply by the total aquarium volume (in gallons):
Aquarium Volume (in gallons) x (Calcium decrease in a day/10) = daily dosage required (ml)
Note: If your calcium needs exceed the suggested dosing amounts per the above formula, increase by 10ml daily until your intended calcium levels are reached. 1 milliliter of calcium will increase calcium concentration ("[Ca2+]") in 1 US gallon (3.785 L) of water by approximately 10 ppm.
