Never add fish while cycling!

The ammonia we’re adding is on purpose — it feeds the good bacteria. But it’s still toxic to fish. Even hardy fish can get burns, stress, or worse. Your new fish deserve a safe, fully cycled tank from day one.

How the cycle works (super simple):

• First few days → ammonia goes down, nitrite goes up
• Next week or two → nitrite goes down, nitrate goes up
• Cycle is finished when you add 1 ppm ammonia and 24 hours later BOTH ammonia AND nitrite = 0 ppm
