В чем разница между щелочностью воды и ее жесткостью?

На печать

Щелочность - это величина, показывающая количество карбоната и бикарбоната калья, растворенного в воде. Щелочность - способ нейтрализовать кислоту, не изменяя pH. Карбонатная жесткость измеряется в градусах (dKH), частях на миллион карбоната кальция (ppm CaCo3), или миллиэквивалентах на литр (meq/L).

Вы должны регулярно производить тесты на щелочность, потому что низкая щелочность позволит колебаться уровню pH, что принесет немало вреда для обитателей аквариума. Держите уровень щелочности в 2-4 dKH в мягкой воде, 8-12 dKH в жесткой и 7-10 dKH для морских аквариумов. Рыбы имеют различную приспособленность к щелочи, например, африканские цихлиды чувствуют себя комфортно при щелочности в 10- 17dKH, в то время как южноамериканские карликовые цихлиды всего в 1- 7 dKH.

Тип воды
Очень мягкая 0-4 0-4
Мягкая 4-8 5-7
Слегка жесткая 8-12 7-8
Умеренно твердая 12-18 9-12
Жесткая 18-30 13-20
Очень жесткая выше 30 Выше 20

В отличие от карбонатной жесткости, общая жесткость показывает общее количество минералов, расстворенных в воде. Тесты для воды обычно показывают содержание солей кальция и магния в воде, и результат показывают в dH и dGH. Этот показатель не критичен для большинства аквариумов, кроме тех, что населены животными и растениями с особенными условиями содержания. Например, в зависимости от растений, пресноводный аквариум может требовать общей жесткости в 3-5 dKH. В то время, как аквариум с африканскими цихлидами потребует жесткости в 10- 15 dKH.
