✂️ Usage tips

Test the water at the first sign of algae growth. High nitrate or phosphate levels indicate overfeeding or too few water changes. Use the test results to choose the correct Tetra product: Tetra Nitrate Minus for high nitrate, Tetra Phosphate Minus for high phosphate.

💡 Tip

Test regularly — even without visible algae — to detect problems early and treat them preventively.
