  1. Step 1 Vai in un negozio di accessori per acquari.
    Any specialty store will do.
  2. Step 2 Cerca una confezione con su scritto "Kit per il test del pH".
    Remember that if you have a freshwater aquarium you need to look for a freshwater kit, while if you have a saltwater aquarium you need to look for a specific kit.
    • Important!If you have viviparous fish, goldfish, African cichlids or saltwater fish and invertebrates, you will need a High Range pH test kit!!It should cost around ten euros.Also get solutions to lower or raise the pH of the aquarium, in case the level detected is too high or too low.
  3. Step 3 Accertati che il kit sia completo.
    The kit must contain a colored paper, a small glass test tube marked up to 5 ml and a bottle with the solution to carry out the pH test.
  4. Step 4 Effettua il test una volta a settimana, dopo aver cambiato l'acqua.
  5. Step 5 Quando sei pronto per effettuare il test, prendi la provetta, la cartina e la soluzione.
  6. Step 6 Immergi la provetta nell'acquario e riempila fino alla linea dei 5 ml.
  7. Step 7 Prendi la boccetta...
    Take the bottle with the solution and put 3 drops (or as indicated in the information leaflet) in the test tube containing the water. Close the test tube with its lid and shake it for 3 minutes (but in some cases 1 minute is enough).
  8. Step 8 Quando hai finito,...
    When you have finished, take the map and, standing in a well-lit place, compare the color of the water in the test tube with the colors illustrated on the map.
    • On the scale, you will see that 6-6.8 is acidic.If this is the result, read the instructions for the pH raising solution to see how much you need to put in the aquarium.The optimal value is 7.0;anything higher than this is alkaline and you will need to use the solution to lower the pH, following the instructions on the package.
  9. Step 9 Regola il pH in base ai pesci che possiedi.
    Tropical fish do well with a pH that varies between 6.5 and 7.5 so aiming for 7.0 is fine.However, saltwater fish do best with a pH of 8.0-8.3.African cichlids thrive at a pH of 8.4 which matches that of Lake Malawi and Lake Tanganyika, but a pH ranging between 7.5 and 8.5 will do.
  10. Step 10 Quando è ora di gettare via il liquido, rovescialo direttamente nello scarico.
    Don't touch it, because it is acidic and can irritate your skin.After pouring the liquid down the drain, rinse the test tube and its lid.
  11. Step 11 Continua a testare l'acqua finché non ottieni un pH di 7,0 e ripeti il procedimento per ogni test che effettui.

Advice

  • If you touch one of the chemical reagents and get burned, rinse your hand immediately and do not touch anything else until it is well rinsed.
  • If you can find them, there are also stick tests for dipping.You simply immerse them in the aquarium and observe the color.They are more expensive, but they are very comfortable and fast.
  • Do not use a wooden surface to test, as the acid will pit and damage it.The best idea is to use a towel.
  • If your pH test kit works differently than these instructions, follow the instructions found in the kit.
