How We Calculate
- • Bioload formula: Based on fish size + activity level + diet.
- • Planted tank bonus: Plants absorb ammonia, allowing higher stocking.
- • Filtration factor: Heavy filtration increases capacity by 20%.
- • Not just inch-per-gallon: We account for temperament and territorial needs.
