Product overview
Coral Essentials Carbonate + Trace is made in Australia. It is a concentrated carbonate and bicarbonate supplement for marine reef tanks, with selected trace elements mixed in.
Hard corals use carbonates to build calcium carbonate skeleton. When alkalinity drops, growth can stall and colonies can become stressed. This 180,000 ppm (10,000 dKH) solution supplies carbonate and bicarbonate, plus boron, bromide, iodide, and sodium fluoride, so you can support alkalinity and those traces from one bottle.
Key features
-
Concentrated carbonate: 180,000 ppm liquid to help hold alkalinity and support skeleton growth.
-
Traces included: Blended with Coral Power Trace C elements, boron, and bromide, so you do not need extra bottles for those micros.
-
Simpler routine: Traces are dosed in a set ratio with each alkalinity addition.
-
SPS growth range: Helps keep alkalinity around 8.5–9.0 dKH, a common target for SPS-heavy tanks.
-
Dosing pumps: Punch a hole in the cap or pour into a reservoir for automatic dosing.
Water and system compatibility
-
Water: Marine / saltwater reef aquariums only. Not for freshwater or planted tanks.
-
Target: About 8.0–9.0 dKH for balanced growth.
Dosing and instructions
Always follow dosage & directions on product packaging.
Choose one of these methods:
Option 1: Daily recipe
Add the starting volume each day in a high-flow area of the sump or display:
-
Soft coral / LPS: 3 ml per 100 litres daily
-
Mixed reef: 6 ml per 100 litres daily
-
SPS dominant: 12 ml per 100 litres daily
Option 2: Calculated dose
-
Strength: 1 ml raises carbonate by 1.8 ppm (0.1 dKH) per 100 litres.
- Test alkalinity regularly to find how much the tank uses each day. Enter those values in the Coral Essentials dosing calculator to set the daily volume.
