Our CANNA CALMAG AGENT increases water hardness, without disrupting the balance of nutrient ratios within the system. By fixing hardness and stabilizing the pH, it also maintains nutrient quality while in the nutrient reservoir. Review: It's calmag - What can I say ? It's calmag. Great supplement when running in coco coir especially if running soft water or reverse osmosis (RO) water. I really like the Canna Coco nutrients and I've have been having great results my first run using them and it's one of the most simple nutrient lines to use. Instead of 7 different bottles I now run 4. 2-4ml of calmag agent and equal parts of A+B. Can't get easier than that. I also got the PK 13/14 but haven't used it yet. Review: Worth it! - Item arrived fast and packaged really well.I was surprised how good this Cal Mag is and I will be buying more of it.I would recommend this seller and product. ## Features - Prevents deficiencies in calcium and magnesium - Increases water hardness - Stabilizes water pH over time - Maintains optimal nutrient quality in the nutrient reservoir - Stronger, healthier plants - Promotes better quality flowers ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.7 out of 5 stars 538 Reviews | ## Images ![CANNA CalMag Agent, 1 L - Image 1](https://m.media-amazon.com/images/I/5174Pg1NcPL.jpg) ## Questions & Answers **Q: What is the npk ?** A: Canna CalMag is 1-0-0 ## Customer Reviews ### ā­ā­ā­ā­ā­ It's calmag *by A***R on May 15, 2026* What can I say ?
