Calculators
Aquarium water-change sequence
Calculation uses the entered values and stated mathematical model; quantities must use the labelled units.
Aquarium systems and maintenance ↗Aquarium batch water preparation
One container processed sequentially; no water-treatment readiness or chemistry recommendation.
Aquarium systems and maintenance ↗Aquarium heater duty from observations
Calculation uses the entered values and stated mathematical model; quantities must use the labelled units.
Aquarium systems and maintenance ↗Aquarium filter turnover adjustment
Hydraulic arithmetic does not imply mixing, filtration or livestock suitability.
Aquarium systems and maintenance ↗Aquarium sump reserve capacity
Static volume budget; equipment displacement and transient surges must be measured separately.
Aquarium systems and maintenance ↗Aquarium evaporation top-up autonomy
Assumes unchanged evaporation and functioning top-up equipment.
Aquarium systems and maintenance ↗Aquarium light photoperiod energy
Calculation uses the entered values and stated mathematical model; quantities must use the labelled units.
Aquarium systems and maintenance ↗Aquarium light coverage footprint
Geometric rectangular beam convention; illumination intensity/uniformity not estimated.
Aquarium systems and maintenance ↗Aquarium aquascape substrate slope
Calculation uses the entered values and stated mathematical model; quantities must use the labelled units.
Aquarium systems and maintenance ↗Aquarium CO2 cylinder runtime
Measured consumption only; no bubble-count conversion or dosing recommendations.
Aquarium systems and maintenance ↗Aquarium air pump branch allocation
Describes measured allocation, not a prediction from unmeasured branch resistance.
Aquarium systems and maintenance ↗Aquarium overflow drain-down volume
All entered pipe volume assumed to drain; actual siphon behavior must be measured.
Aquarium systems and maintenance ↗Aquarium return pump measured curve
Calculation uses the entered values and stated mathematical model; quantities must use the labelled units.
Aquarium systems and maintenance ↗Aquarium hose cleaning workload
Calculation uses the entered values and stated mathematical model; quantities must use the labelled units.
Aquarium systems and maintenance ↗Aquarium filter-media compartment fit
Volume capacity only; package shapes and water-flow restrictions not modelled.
Aquarium systems and maintenance ↗Aquarium conductivity blend estimate
Approximate linear conductivity blend; same temperature, no reaction or ion-specific modelling.
Aquarium systems and maintenance ↗Aquarium salinity mass balance
Mass fraction, not practical salinity units; no livestock target.
Aquarium systems and maintenance ↗Aquarium temperature mixing capacity
Water only, no phase change; tank and décor thermal mass excluded.
Aquarium systems and maintenance ↗Aquarium backup aeration duration
Same battery/conditions assumed; load-dependent efficiency and aging can change runtime.
Aquarium systems and maintenance ↗Aquarium monitoring workload
Workload estimate, not a biological monitoring-frequency recommendation.
Aquarium systems and maintenance ↗Aquarium maintenance cost attribution
Calculation uses the entered values and stated mathematical model; quantities must use the labelled units.
Aquarium systems and maintenance ↗Aquarium quarantine booking check
User-entered intervals only; no medical quarantine duration or treatment advice.
Aquarium systems and maintenance ↗Aquarium feeding inventory ledger
Inventory only; daily amount entered by owner, no feeding recommendation.
Aquarium systems and maintenance ↗Aquarium leak-test level correction
Comparable evaporation conditions assumed; signed result may be negative due to measurement error.
