ZOOLEK Test NO3 - do oznaczania zawartości azotanów

Aquatest NO3 - służy do oznaczania zawartości azotanów, końcowego produktu przemiany azotu białkowego. Umożliwia pomiar w zakresie 0-130 mg/l. Pomiar wykonywany jest metodą kolorymetryczną - do odmierzonej próbki wody dodaje się kolejno odczynniki w/g instrukcji, a wywołaną barwę porównuje z krążkami skali barwnej.

Skład zestawu:
- 2 buteleczki z roztworami odczynników
- pojemniczek z proszkiem reduktora
- skala barwna
- szpatułka
- probówka
- strzykawka
- instrukcja

Po co mierzyć zawartość azotanów?

Azotany stanowią pożywkę dla glonów i z tego powodu ich stężenie powyżej 40 mg/l w akwariach i ozdobnych sadzawkach jest niepożądane.

W stężeniu powyżej 80 mg/l stają się szkodliwe dla ryb, w wysokim stopniu szkodliwe w stężeniu powyżęj 120 mg/l.

Przekroczenie dopuszczalnych zawartości azotanów świadczy o nadmiarze odpadowych substancji białkowych.

Jakkolwiek obecność azotanów w wodzie akwarium jest znacznie mniej niebezpieczna niż amoniaku i azotynów, należy kontrolować i w porę ograniczać ich ilość.

Jak zapobiegać nadmiarowi azotanów?

Przy stężeniach przekraczających 40 mg/l należy dokonać częściowej lub prawie całkowitej wymiany wody w zależności od poziomu przekroczenia dopuszczalnego stężenia. Nadmiar azotanów świadczy o potrzebie oczyszczenia akwarium, podłoża i filtrów, niekiedy wskazuje również na konieczność ograniczenia ilości ryb.
