I’ve been using ATI Essentials + #1 for three months now and my tank’s water stability has improved significantly. The KH levels stay consistent without frequent adjustments. The trace elements are well balanced and my corals have shown better coloration and growth.

This product works well for maintaining stable water chemistry. I noticed less pH fluctuation since adding it. The 10L size is perfect for my medium-sized reef tank. I don’t need to supplement other elements regularly.
