Dayactirka jiilaalka ayaa inta badan diirada saaraya biyaha barkada sababtoo ah hoos u dhaca heerkulka.Ma jiro baraf iyo baraf meelaha qaar, laakiin sidoo kale waa in fiiro gaar ah loo yeesho ka hortagga kaneecada iyo duqsiga biyaha barkada.

Haddii barkadu ay ku taal meel qabow, ilaali barkada jiilaalka ka hor inta aan heerkulku hoos u dhicin 0 darajo Celsius, iskuna day inaad xidho barkada ka hor December si aad uga hortagto baraf.Sababtoo ah balaarinta mugga biyaha ee qalabka barkada inta lagu jiro habka barafka, waxay u socotaa inay keento khasaare dhaqaale oo badan marka tuubooyinka iyo qalabka la dillaaco.

     1.Nadiifi barkada
Biyaha laguma sifayn doono ama laguma dawayn doono kiimiko ahaan xilliga jiilaalka, markaa aad bay muhiim u tahay in la hubiyo in biyuhu aanay wasakh ahayn marka aad furto barkadda guga.
     2.Nadiifi nidaamka shaandhaynta
U deji shaandhada qaabka "Backwash" ilaa ay biyuhu mar kale caddaan noqonayaan.Kadib shaandhada u beddel "luqso" ilaa afar daqiiqo.
3.Ku dar xal ka-hortagga qaboojinta
4.Isticmaalka daboolka barkada
Si looga hortago roobka jiilaalka iyo barafka, isla mar ahaantaana si looga fogaado skimmer ama tuubooyinka barafku waxyeelada
     5.Ka jar nidaamka korontada
Dhig bamka iyo qalabyada yar yar (ka fur cabirka cadaadiska, dhalada yar ee wax lagu eego) qolka kaydinta si aad uga hortagto baraf xilliga jiilaalka.

Dib ha u furin ilaa xagaaga kulul.Way fiicantahay in la furo daboolka ka hor 21 darajo Celsius si ay u fududaato nadiifinta barkada sababtoo ah algae waxay jecel yihiin inay koraan agagaarka 21 darajo Celsius.
