Messen Sie immer zur gleichen Tageszeit, dosieren Sie auf Ihren Zielwert nach und passen Sie den Rhythmus an Ihre Messwerte an. Mit Dosierschwimmer, Salzelektrolyse oder Cyanurs\u00e4ure von 20 bis 50 mg\/l sinkt der Verbrauch, und Sie m\u00fcssen seltener nachlegen.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1790201974311\"><strong class=\"schema-faq-question\">Wie hoch sollte der Wert f\u00fcr freies Chlor im Pool sein?<\/strong> <p class=\"schema-faq-answer\">In \u00f6ffentlichen B\u00e4dern gelten nach DIN 19643 meist 0,3 bis 0,6 mg\/l freies Chlor, f\u00fcr Privatpools nennen die meisten Hersteller etwa 0,5 bis 1,0 mg\/l. Verwenden Sie stabilisiertes Chlor (Dichlor, Trichlor) und ist Cyanurs\u00e4ure im Wasser, braucht es mehr, mindestens rund 7,5 % des Cyanurs\u00e4urewerts, wie die Tabelle oben zeigt. Messen Sie freies Chlor, nicht Gesamtchlor: Die Differenz ist gebundenes Chlor, und liegt sie \u00fcber etwa 0,5 mg\/l, ist eine Sto\u00dfchlorung f\u00e4llig.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1790201991622\"><strong class=\"schema-faq-question\">Wie berechnet man, wie viel Chlor in den Pool muss?<\/strong> <p class=\"schema-faq-answer\">Multiplizieren Sie die gew\u00fcnschte Erh\u00f6hung in mg\/l mit dem Poolvolumen in Litern und teilen Sie durch 1.000: Das ergibt Gramm aktives Chlor. Teilen Sie dann durch den Wirkstoffgehalt des Produkts, bei Fl\u00fcssigchlor mit 150 g\/l durch 150 (Ergebnis in Litern) und bei Granulat durch den Prozentwert (Ergebnis in Gramm). Beispiel: 10.000 Liter um 1 mg\/l anzuheben braucht 10 g aktives Chlor, das sind etwa 67 ml Fl\u00fcssigchlor mit 150 g\/l oder 15 g Calciumhypochlorit mit 65 %.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1790202008933\"><strong class=\"schema-faq-question\">Wie viele Chlortabletten braucht ein Pool?<\/strong> <p class=\"schema-faq-answer\">Eine 200-g-Tablette mit 90 % Trichlor enth\u00e4lt rund 180 g aktives Chlor, gibt es aber \u00fcber mehrere Tage im Dosierschwimmer oder Dosierer ab. Rechnen Sie deshalb mit dem Wochenbedarf statt mit einer Sofortdosis: Tagesverbrauch (mg\/l \u00d7 Liter \u00f7 1.000, in Gramm) mal sieben, geteilt durch 180 g je Tablette. Legen Sie Tabletten nie lose auf den Beckenboden. Trichlor erh\u00f6ht au\u00dferdem die Cyanurs\u00e4ure und senkt den pH-Wert.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1790202026244\"><strong class=\"schema-faq-question\">Wie viel Chlor braucht ein frisch bef\u00fcllter Pool?<\/strong> <p class=\"schema-faq-answer\">Lassen Sie die Pumpe nach dem Bef\u00fcllen einige Stunden laufen, stellen Sie zuerst den pH-Wert auf 7,2 bis 7,6 ein und dosieren Sie dann Chlor auf Ihren Zielwert, meist 0,5 bis 1 mg\/l ohne Stabilisator. Messen Sie nach ein paar Stunden nach und dosieren Sie bei Bedarf nach. Eine Sto\u00dfchlorung ist bei klarem Frischwasser normalerweise nicht n\u00f6tig, Sie brauchen sie erst bei Algen oder Tr\u00fcbung.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1790202043555\"><strong class=\"schema-faq-question\">Wie nutze ich den Rechner f\u00fcr eine Sto\u00dfchlorung?<\/strong> <p class=\"schema-faq-answer\">Setzen Sie das Ziel auf den Sto\u00dfwert, \u00fcblicherweise 5 bis 10 mg\/l, bei Cyanurs\u00e4ure etwa 40 % davon, zum Beispiel 16 mg\/l bei 40 mg\/l Cyanurs\u00e4ure. Geben Sie die Dosis in ein bis zwei Runden bei laufender Pumpe zu und messen Sie alle paar Stunden nach, bis das Wasser klar ist. Erst wieder baden, wenn der Wert im normalen Bereich liegt.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1790202060866\"><strong class=\"schema-faq-question\">Warum steigt der Chlorwert nach dem Dosieren nicht?<\/strong> <p class=\"schema-faq-answer\">Meist liegt es an der Chlorzehrung: Organische Stoffe wie beginnende Algen, Schwei\u00df und Sonnencreme verbrauchen das Chlor so schnell, wie Sie es zugeben. Lassen Sie das Wasser vor dem Messen mindestens 30 Minuten umw\u00e4lzen und pr\u00fcfen Sie, ob Ihr Testset noch frisch ist. Bleibt der Wert trotzdem unten, braucht der Pool eine Sto\u00dfchlorung, um die Zehrung zu beseitigen.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1790202078177\"><strong class=\"schema-faq-question\">Wie lange nach dem Chloren kann man wieder baden?<\/strong> <p class=\"schema-faq-answer\">Nach einer normalen Nachdosierung warten Sie, bis die Pumpe das Wasser umgew\u00e4lzt hat, meist 30 bis 60 Minuten, und pr\u00fcfen Sie, dass das freie Chlor im normalen Bereich liegt. Nach einer Sto\u00dfchlorung baden Sie erst wieder, wenn der Wert im normalen Bereich ist, was je nach Sonne und Cyanurs\u00e4ure einen Tag oder l\u00e4nger dauern kann. Messen Sie, statt zu sch\u00e4tzen.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1790202095488\"><strong class=\"schema-faq-question\">Erh\u00f6hen Trichlor und Dichlor die Cyanurs\u00e4ure, und was macht Fl\u00fcssigchlor mit dem pH-Wert?<\/strong> <p class=\"schema-faq-answer\">Ja. Jedes 1 mg\/l freies Chlor aus Trichlor bringt etwa 0,6 mg\/l Cyanurs\u00e4ure ins Wasser, bei Dichlor sind es etwa 0,9 mg\/l. Cyanurs\u00e4ure baut sich nicht ab, sie sinkt nur durch Wasseraustausch. Calciumhypochlorit erh\u00f6ht die Kalkh\u00e4rte um etwa 0,7 mg\/l je mg\/l Chlor. Fl\u00fcssigchlor bringt weder das eine noch das andere mit, hebt aber den pH-Wert, w\u00e4hrend Trichlor ihn senkt.
