🔄 New Tank Syndrome (Cycling)

New Tank Syndrome refers to the toxic conditions that occur in aquariums before beneficial bacteria establish. Understanding and completing the nitrogen cycle is the most important factor in successful fishkeeping.

📋 Quick Facts

Duration4-8 weeks typically
ProblemAmmonia/nitrite poisoning
SolutionEstablish beneficial bacteria before adding fish

🔄 The Nitrogen Cycle

  1. Ammonia - Produced by waste, very toxic
  2. Nitrite - Bacteria convert ammonia, still toxic
  3. Nitrate - Bacteria convert nitrite, much less toxic

Cycle is complete when ammonia and nitrite read 0, with nitrate present.

💊 Fishless Cycling Method

  • Add ammonia source (pure ammonia or fish food)
  • Maintain 2-4 ppm ammonia
  • Test daily, watch for nitrite then nitrate
  • When ammonia/nitrite hit 0 within 24 hours, cycle complete
  • Takes 4-8 weeks

đŸ›Ąī¸ Prevention

  • Always cycle before adding fish
  • Use bacterial supplements to speed cycle
  • Add fish slowly after cycle completes
  • Test water regularly first month

📚 Summary

Cycling is non-negotiable for healthy aquariums. Patience during this 4-8 week process prevents fish deaths and establishes a stable ecosystem.
