Coral Essentials Coral Power Boron – 50ml
Our Coral Essentials Boron Solution is a concentrated liquid additive containing 50,000 ppm (mg/L) of boron. Natural seawater contains boron at levels of 4–5 ppm. Boron plays a key role in the formation of coral skeletons, co-precipitating with calcium carbonate. It also provides mild pH buffering in marine aquarium systems.
For advanced aquarists, regular testing of boron levels is recommended to monitor uptake and adjust dosing accordingly. Calculate your required dosage based on test results and depletion rates. Monitor boron levels every week or two to maintain optimal conditions.

Jane Nash –
I’ve been using this boron solution for three months now and noticed improved coral growth, especially in my Acropora species. The instructions were clear and I followed the dosing based on weekly tests. It’s a small addition, but makes a noticeable difference in skeletal development.

The product arrived quickly and the label was easy to read. I tested the boron level after two weeks and found it stable. My polyps have become more active, which I attribute to consistent boron supplementation.

As an advanced aquarist, I rely on precise nutrient management. This boron solution is reliable and matches the concentration I need. I check levels every two weeks and adjust dosing accordingly. No issues so far.
