Salifert

Salifert is IndieFur’s go-to marine reef test kit brand, covering the full water-parameter range serious reefers track — Calcium, Magnesium, KH/Alkalinity, Nitrate, Phosphate, Copper, Iodine, Strontium, and pH — plus a dedicated Flatworm Exit treatment. If you’re only buying one brand of test kits for a reef tank, this is usually the first one recommended.
