I’ve used Reef Foundation A for three months now and noticed a significant improvement in my coral coloration and structure. The water chemistry stays stable, and my corals appear healthier than before. Easy to mix and effective in maintaining calcium and strontium levels.

The product works well in my 120-gallon reef tank. I’ve seen better growth in my polyps, especially in the soft corals. I mix it once a week based on test results. Slight improvement in water clarity after a few weeks.
