Tank Turnover & Pump RateAquaculture Tech
Determine water exchange rate per hour and cycle duration based on tank volume and pump flow rate specifications.
Aquatic ecosystems are dynamic biological buffers. Physical parameters like dissolved oxygen levels must be cross-checked with biological and chemical filtration limits to maintain optimum fish welfare.
Excellent circulation. Keeps solid wastes suspended for immediate mechanical bead filtering.
