Tetra Crystal Water

Crystal clear aquarium water in 6–12 hours — mild mineral formula

250 ml — safe for fish and plants — not for shrimp and invertebrates

✅ Level: Easy — Dose and wait. First effects visible after 2–3 hours.

Tetra Crystal Water makes cloudy aquarium water crystal clear in just 6 to 12 hours. The carefully selected mineral formula gently binds suspended dirt particles, which are then collected by the filter — without clouding the water or leaving residue. Ideal for starting a new aquarium, after a water change, or when the water unexpectedly becomes cloudy.

⚠️ Note: Not suitable for aquariums with shrimp, snails, or other invertebrates.

💡 Tip

Ideal for starting a new aquarium — cloudy water in the first few weeks is normal, and Tetra Crystal Water quickly resolves this without disturbing the biological cycle.

❓ Frequently Asked Questions

Why is the water cloudy after startup?
Cloudy water in a new aquarium is caused by a bacterial bloom — a normal part of cycling. Tetra Crystal Water binds the suspended particles so the filter can collect them.

Can I use Crystal Water in a shrimp aquarium?
No — Tetra Crystal Water is not suitable for aquariums with shrimp, snails, or other invertebrates. Remove them before use or choose an alternative product.
