Aquarium water changes Aquarium water changes are vital to keeping a healthy aquarium and a very common question amongst new aquarists is, how often do I do a water change, and how much? Unless you are lucky enough to have a tropical river running through your home, there is no escaping water changes if you want to keep a happy, healthy aquarium. So in this article, I am going to cover the ins and outs of water changes, so that by the end of this you will understand why water changes are necessary and how to work out when you need to do them.
Water Testing - Checking Water Chemistry Water chemistry is a key factor in keeping a healthy aquarium. I've seen many new starters looking for help online with aquarium issues over the years, only for them to then state that they don't own a water testing set. If you're new to aquariums then I can tell you that a testing kit is essential, never more so than at the start. Even as an experienced aquarist with very mature aquariums, I still like to have a test kit handy for the occasional check. If for any reason you are unable to acquire a testing kit, any good aquarium shops will be happy to test your water for you, sometimes for a small fee, but if you're lucky for free.
