How do I know my filter capacity?

Filter capacity is specified by the manufacturer, typically in grams of ammonia or total organic load the media can process before saturation or replacement.

What affects filter life?

Biomass, feeding rate, and water temperature all affect filter loading. Higher temperatures increase bacterial activity and waste production.

What happens if I do not replace the filter on time?

Saturated filters stop removing waste, leading to ammonia and nitrite spikes that can stress or kill fish.

Filter Life Estimator

Estimate when your aquaculture filter needs replacement based on biomass and feed load. Never miss a filter change.

Filtration in Aquaculture

Biological and mechanical filters are essential in recirculating aquaculture systems (RAS). Filter media has a finite capacity determined by the organic load it processes. Feed is the primary source of organic waste, so filter life is directly proportional to daily feed input. Proactive filter replacement prevents water quality crashes.
