NT Labs Aquarium Tonic Salt Osmotic Support Treatment (300g) | Minimises fish stress and provides vital osmotic support. Reduces toxic nitrite levels. Ideal as a general aquarium tonic.

【 PROMOTES HEALTHY FISH】: Freshwater fish constantly regulate their internal salt concentration through a process called osmoregulation. When fish become stressed or diseased this process becomes dysfunctional, and fish begin to lose control of this salt regulation. Tonic Salt provides osmotic support and assists with recovery from stress and disease. 【 REDUCES TOXICITY OF NITRITE】: At high levels, Nitrite can be toxic to fish. Monitor nitrite levels using the NT Labs range to test kits, and dose Tonic Salt to help bring nitrite levels down. 【 MULTIPLE USES 】This product has multiple dose rates for different outcomes, please see the label for full instructions. 【 EASY TO USE 】: Calculate the volume of your aquarium in litres (Length x Width x Depth (in cm)/1,000). Dissolve the required amount in a small volume of aquarium water before adding to your aquarium. 【 SUITABLE FOR ALL AQUARISTS 】: The ease of use of Aquarium Tonic Salt means it is perfect for use by beginners and seasoned aquarists alike.
