Detailed Analysis

Explanation

Based on your 4 hardy fish (avg 8cm) in a 100L tank with moderate canister filter, moderate feeding, and moderate plant coverage: Your tank has an unsustainable bioload (1.51), so the maximum safe 50% water change every 3 days is recommended. Consider reducing fish count or improving filtration.

Safety Notes

  • Hardy fish can handle larger water changes, but 50% is the maximum safe limit
  • Clean moderate canister filter every 7 weeks for optimal performance
  • Always match temperature and treat new water with dechlorinator
  • Test water parameters before and after changes
  • Never change more than 50% of water at once
