Anthony Jackson –
Used this salt for my 100-gallon reef tank. The water stability improved noticeably after a few weeks. My corals are thriving and the water chemistry remains balanced. No signs of algae growth, which was a problem before.
Madeleine Miller –
After switching from a commercial salt mix, my shrimp and clams are more active. The water clarity has improved, and the pH remains stable. Highly recommended for reef keepers.
Lucas Randall –
The salt is easy to measure and mix. I’ve used it in both saltwater and planted tanks. The trace elements seem to support plant growth, though I still monitor water parameters regularly.
