It also contains plant extracts, vitamins and minerals for health and growth. **Q: How and when should I use Tetra AquaSafe?** A: Shake well before use. For new tap water, add 5 ml per 10 litres to the aquarium. The blue colour disappears when distributed. Always use when reinstalling, changing water or refilling. **Q: Is Tetra AquaSafe suitable for marine aquariums?** A: Yes. AquaSafe's fast dissolving formula is suitable for both fresh and marine water systems. For saltwater aquariums, should be switched off briefly during the use of the protein skimmer to avoid excessive foaming. **Q: How does Tetra AquaSafe support the biological balance in the aquarium?** A: In addition to neutralising harmful substances, Tetra AquaSafe promotes beneficial bacteria and ensures clear, biologically stable water. Regular water tests are recommended to control values and adjust if necessary. **Q: Can I use Tetra AquaSafe with other Tetra products?** A: Absolutely! Tetra AquaSafe combines great with Tetra EasyBalance to control nutrient levels and with Tetra FilterActive Bacteria to promote the growth of beneficial bacteria for a truly healthy aquatic habitat. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very effective, a must for fish tanks *by A***R on 25 May 2026* Far the cheapest on the internet, it lasts quite a while.
