Questions & Answers

1 Customer Questions

Can fish be put in a new tank with this substrate immediately after setting it up?

Answer by Chewy • Jan 21, 2025
Biosubstrate helps jumpstart the cycling process by introducing beneficial bacteria immediately, significantly reducing cycle time. However, it does not completely eliminate the need for cycling. The duration of the cycle will depend on several factors, including bioload (the amount of fish waste), feeding frequency, nutrient removal, and filtration efficiency. To ensure a stable and healthy aquarium, introduce fish gradually as ammonia and nitrite levels drop to zero and nitrate levels begin to rise. Regular water changes will help keep nitrate levels in check, creating an optimal environment for your fish to thrive.
