Deltec filter NF 509-1020

Deltec svavelnitratfilter NF 509 - NF 1020

Regelbunden utfodring av fiskar och ryggradslösa djur kan leda till en farlig koncentration av nitrat. Det är tveklöst att biologiskt avlägsnande av nitrat är mycket meningsfullt såväl i det marina som i sötvattensakvariet.


Biologisk nitratborttagning

Anaeroba bakterier kan reducera nitrat till andra ämnen. Detta kan bara hända under anaeroba vattenförhållanden (utan syre). För att säkerställa ett effektivt avlägsnande av biologiskt nitrat måste vissa förutsättningar vara uppfyllda

- Anaeroba vattenförhållanden i nitratfiltret genom en "droppvis" vattenförsörjning.

- Mätbart nitratinnehåll i akvarievattnet.

- Det aeroba filtreringssystemet måste vara väl etablerat

Starta upp

- Innan Deltec svavelnitratfilter ansluts till akvariet bör filtret sköljas noggrant för att ta bort dammiga partiklar.

- Anslut mikrofiltrets inlopp till en pump eller bypass i akvariet. Utloppet ska inte ledas direkt till akvariet.

- Justera vattenflödet initialt för att lägga till. 1 droppe/sekund och låt filtret köra så här i minst 2-3 veckor, kontrollera flödet ofta.

Under "inkörningsperioden" kan nitritnivån (NO2) och nitrat (NO3) öka mätt vid filterets utlopp. Detta är inte farligt så länge det aeroba filtersystemet och akvariet är mogna. Även pH -värdet kan vara mycket lågt. Det rekommenderas därför att köra utloppet i en behållare fylld med ett kalkstensmedium som används i kalciumreaktorer.

Viktigt

- "inkörningsperioden" för Deltec svavelnitratfilter är relativt lång, det kan ta upp till 8 veckor eller ännu längre!

- Mät nivåerna nitrit (NO2) och nitrat (NO3) regelbundet vid filterutloppet. Om både nitrit- och nitratnivåerna är 0 mg, öka flödet något (till exempel 2 droppar per sekund) och mät igen NO2/NO3 vid utloppet.

- Ökningen av vattenflödet bör göras stegvis i små mängder samtidigt för att fastställa det maximala möjliga flödet för systemet.

- Öka inte flödet för mycket, eftersom detta kan "tippa" filtret och orsaka oönskade reaktioner. Om detta händer måste filtret startas om med ett flöde på 1 droppe/sekund.
