When I started working in the marine aquarium hobby in the mid nineties, color changing and titration test kits is what we used to measure everything in our aquarium water. However even back then colorimeters were available, but research-grade pricing made them just a twinkle in our eye of what the future could hold. Names like Hach and LaMotte would make aquarium chemistry nerds swoon at the thought of ever being able to use a ‘water testing computer’.

There is even a safety component to be considered when doing water testing. Test vials should never be rinsed in the aquarium or pond. The test sample must not be poured back into the aquarium or pond. Some reagents are highly toxic (i.e., Nessler’s reagent contains mercury compounds) and some even contain highly carcinogenic chemicals (cadmium in nitrite and low-range nitrate kits and orthotolidine in some chlorine and ozone kits). One’s finger tips should never be used to close the opening of a test vial — this will not only effect the accuracy of the test, but contamination of the skin with the test chemicals will occur.

Keeping tropical fish healthy in an enclosed environment involves not only regular tank maintenance but also some knowledge of how to test your water and what to look for when you have the results of those tests in front of you. You have got to remember that just because the water looks nice and clear, that doesn't necessarily mean that the water is in good condition, for all you know your aquarium water may contain some extremely dangerous toxins that are lethal to fish. So before you put water in your tank, you must purchase some good quality water testing kits that will test ammonia, nitrite, nitrates and pH, these are the four elements that you must test for on a regular basis, even after your aquarium is fully established. It doesn't matter whether your aquarium has been set up for one month, or 10 years, you will always need to have some water test kits at hand.Nitrate is the byproduct of ammonia and nitrite and is nowhere near as toxic as ammonia or nitrite. Very high levels of nitrate can stress fish and make them more susceptible to disease. It should also be kept very low if you are breeding. Nitrate can only be removed/lowered by doing water changes rather than being removed by nitrifying bacteria. Nitrate levels should be kept at 40 ppm or below. If you keep your fish in a suitable environment, it is extremely easy to keep the nitrate levels below 20 ppm by doing regular water changes. If you keep your Oscar in a tank that is too small, you may find that nitrate levels rise very quickly.
It is important to know what the pH of your water is. Basically, the pH value indicates whether the water is acidic, alkaline or neutral. Without going into detail, a pH level of 7.0 is classed as neutral. If the pH level falls below 7.0, it is classed as acid, if it rises above 7.0, it is classed as alkaline.
Water test kits should be bought with the aquarium before you add any fish. To set up an aquarium and biological filter properly, you need to test the water on a regular basis. Trying to set up a fish tank without knowing what is going on with the water could very well put your fish at risk so please remember to ask for a water test kit when you are buying your aquarium.
Nearly every aquatic company manufacture their own water test kits. Since keeping Oscars, I have used three companies. They are, , and They all work very well but If you were to ask me which I preferred, then it would have to be Aquarium Pharmaceuticals. The main reason why I prefer the test kits manufactured by this company is the longest you have to wait for the results is five minutes, rather than 20 minutes for some of the others. They don't come cheap but you get a lot for your money
Some people prefer to take their water to the local aquatic centre for testing. Many shops will do it for free, or maybe charge you a very small fee. Whereas there is nothing wrong with doing it this way, I prefer to do the testing myself. This means that you can test the water at any time. If you have a problem during the holiday period when the shops are not open, you could put your fishes health at risk whilst waiting for the aquatic centre to open up again. Testing water really is extremely easy, you don't have to be a scientist to do it. It's just a case of adding a few drops of a special chemical to a small amount of tank water and then waiting a few minutes for the results.
