Water Tests - Aquarium Maintenance

Regular testing is important to get a complete picture of water quality.

It is therefore wise to do a drop test monthly, as this will give you a more complete and precise picture.

Almost all water values ​​are connected to each other. A complete picture of your water quality is therefore of great importance.

Are the water values ​​too high or too low? Then take action to correct this.

If you really want to do it right, consider the needs of the plants and fish in your aquarium. For example, some plants need some extra calcium and there are shrimps that prefer a lower pH value.

We have different types of water tests such as test strips, individual drop tests and complete test kits, which are listed below.

===SEOTEXT===

Most strips can measure the following water values: PH (acidity), GH (general hardness), KH (carbonate hardness), NO2 (nitrite), NO3 (nitrate) and CL2 (chlorine).

With a drop test you can also test the NH3 (ammonia), NH4 (ammonium), PO4 (phosphate) and FE (iron) values.

For example, a pH that is too high causes NH4 (ammonium) to convert more quickly into NH3 (ammonia), which is harmful to your fish.

If the water values ​​are too high, a water change and less feeding is the solution in most cases.
When changing the water in this situation, make sure that the values ​​do not change too quickly. Add clean water in stages so that the plants and fish can get used to it gradually.

Are the water values ​​too low? Then fertilization is in most cases the solution.

Om een compleet beeld te krijgen van de waterkwaliteit is regelmatig testen belangrijk.

Het is dus verstandig om maandelijks een druppeltest te doen, deze geven u een completer én preciezer beeld.

Bijna alle waterwaardes zijn met elkaar verbonden. Een compleet beeld van uw waterkwaliteit is dus van groot belang.

Zijn de waterwaardes te hoog of te laag? Kom dan in actie om dit op te heffen.

Wilt u het écht goed aanpakken? Houd dan rekening met de wensen van de planten en vissen in uw aquarium. Zo hebben bijvoorbeeld sommige planten juist behoefte aan wat extra calcium en zijn er garnalen die graag een lagere PH waarde hebben.

We hebben verschillende soorten watertests zoals teststrips, losse druppeltesten én complete testkoffers die hieronder staan.

Met de meeste strips zijn de volgende waterwaardes te meten: PH (zuurtegraad), GH (gezamenlijke hardheid), KH (carbonaathardheid), NO2 (nitriet), NO3 (nitraat) en CL2 (chloor).

Met een druppeltest kunt u bijvoorbeeld ook de NH3 (ammoniak), NH4 (ammonium), PO4 (fosfaat) en FE (ijzer) waardes testen.

Zo zorgt een te hoge PH er bijvoorbeeld voor dat NH4 (ammonium) zich sneller omzet in NH3 (ammoniak) en dit is schadelijk voor uw vissen.

Zijn de waterwaardes te hoog, dan is een waterwissel en minder voeren in de meeste gevallen de oplossing.
Let er bij een waterwissel in deze situatie wel op dat de waardes niet te snel veranderen, vul het schone water aan in etappes zodat de planten en vissen hier geleidelijk aan kunnen wennen.

Zijn de waterwaardes te laag? Dan is bemesting in de meeste gevallen de oplossing.
