Claims (14)

1. Fremgangsmåde til at betjene en pumpe (12) i et akvakultursystem (10), hvilket akvakultursystem (10) omfatter en kulturbeholder (20) der huser akvatisk liv, en pumpe (12) med variabel hastighed, en sensor (22), en iltkegle (26) i direkte fluidforbindelse med kulturbeholderen (20) gennem en iltsolenoidventil (24), et biofilter (16) i fluidforbindelse med kulturbeholderen (20) og pumpen (12), og en programmerbar styreenhed (14) i forbindelse med sensoren, iltsolenoiden, og pumpen, hvilken fremgangsmåde omfatter: at recirkulere vand gennem kulturbeholderen (20) ved en gennemløbshastighed; at recirkulere vand gennem biofilteret (16); at måle et niveau af opløst ilt i kulturbeholderen (20) med sensoren; idet den programmerbare styreenhed bestemmer en gennemløbshastighedstærskel baseret på niveauet af opløst ilt og iltbehovet for det akvatiske liv i kulturbeholderen; at finde et aktuelt niveau for opløst ilt målt med sensoren; at sammenligne gennemløbshastighedstærsklen med det aktuelle niveau for opløst ilt målt med sensoren; og når det aktuelle niveau for opløst ilt er under gennemløbshastighedstærkslen, øger den programmerbare styreenhed en hastighed på pumpen (12) for at øge gennemløbshastigheden gennem kulturbeholderen (20) og betjener iltsolenoidventilen (24) til at styre en iltstrøm ind i kulturbeholderen (20) indtil koncentrationen af opløst ilt er større end eller lig med den fastsatte gennemløbshastighedstærskel.
2. Fremgangsmåde ifølge krav 1 og endvidere omfattende overvågning af mindst en af ammoniak, nitrit, nitrat og faststoffjernelse.
3. Fremgangsmåde ifølge krav 2 og endvidere omfattende overvågning under anvendelse af sensorer i biofilteret (16).
