Więcej informacji

W zestawie wykorzystano odczynnik mierzący pH w dość wąskim zakresie, nadający się do stosowania w akwariach morskich o pełnym i częściowym zasoleniu. Odczyn wody w zbiorniku powinien wynosić pomiędzy 8,2 – 8,4. W zbiornikach, do których dodawana jest woda wapienna, odczyn może wzrastać do 8,6.

Twardość ogólna naturalnej wody morskiej wynosi między 2 a 3 meq/l. W zbiorniku słonowodnym wartość ta powinna wahać się pomiędzy 4 a 6 meq/l. Test służy do pomiaru ogólnej twardości, będącej sumą zawartych w wodzie węglanów (CO3 2-), wodorowęglanów (HCO3 -), boranów (B(OH)4 -) i wodorotlenków (OH-), wyrażonej jako pojemność buforowa wody w stosunku do kwasów, podana w meq/l (miligramorównoważnikach na litr). Ten sposób wyrażenia twardości jest prawidłowy chemicznie. Stosowanie innych jednostek, takich jak KH, dH, CaCo3/l, itp., może być mylące. 1meq/l odpowiada 2,8oKH.

Test wystarcza na przeszło 75 pomiarów.
