Instant Ocean Accelerator 250ml
Marine invertebrates such as corals, sea stars, tube worms, and clams require balanced levels of essential elements in their seawater environment. Reef Accelerator replenishes key nutrients including calcium, magnesium, strontium, and other vital components to support healthy growth and vibrant coloration.
Recommended for reef tanks with dense coral populations that may demand higher calcium levels. Use regularly to maintain stable element concentrations. For calcium levels below 400 ppm, use the Instant Ocean Calcium Booster instead.
Encourages coral growth and the development of purple algae. Formulated with advanced chemistry to deliver all essential elements without the need for mixing or complex reactor systems.
Free from nitrates, phosphates, and silicates to ensure a clean, stable marine environment.
| Component | Level |
|---|---|
| Calcium | 400 ppm |

I’ve used this for three months in my 100-gallon reef tank. The corals have grown more vibrant and the purple algae has appeared naturally. No mixing required, which makes it easy to use. Water parameters stayed stable without any spikes.

Good for maintaining calcium and magnesium. I noticed better color development in my soft corals after a few weeks. I still use the calcium booster when levels drop below 400 ppm, but this product works well as a regular supplement.

Simple to add and effective. My tank has dense stony corals and this product helped maintain balance without introducing harmful elements. No side effects or changes in water chemistry I could detect.
