To ensure your pond stays in top condition, it's crucial to regularly test the water parameters. This allows you to make timely adjustments and ensure an ideal living environment for your fish and aquatic plants. We recommend testing your pond's water parameters once a month.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003ch2\u003e \u003cstrong\u003eWhich water parameters should I test in my pond?\u003c\/strong\u003e\n\u003c\/h2\u003e\n\n\u003cp\u003e The water parameters in your pond are all interconnected through various processes. You'll find many articles on these different water parameters in our knowledge base. Below, we summarize the most important water parameters for your pond.\u003c\/p\u003e\n\n\u003ch3\u003e pH value pond\u003c\/h3\u003e\n\n \u003cp\u003eIf the pH is too low or too high, or even fluctuates significantly, your fish will experience stress. This manifests as bloodshot gills and fins, and their mucous membranes can become damaged. Stress makes fish more susceptible to disease, as it significantly reduces their resistance and can ultimately be fatal. Moreover, the beneficial bacteria in your pond and filter will function less effectively at an unfavorable pH, creating a downward spiral where the pH deteriorates even faster. It is therefore essential to regularly monitor and adjust the pond's pH. The \u003cstrong\u003eideal pH\u003c\/strong\u003e for your pond is preferably between 7 and 8.5. If you have a koi pond or a pond exclusively containing other cyprinids, the pH is considered optimal between 8.0 and 8.5. \u003cbr\u003e\u003ca href=\"\/en\/collections\/waterverzorging\" title=\"GH plus\" data-mce-fragment=\"1\" data-mce-href=\"\/en\/collections\/waterverzorging\"\u003eView our resources to change the pH value here\u003c\/a\u003e .\u003cbr\u003e\u003c\/p\u003e\n\n\u003ch3\u003e GH value pond\u003c\/h3\u003e\n\n\u003cp\u003e The GH value indicates the dissolved minerals in your pond water, with important minerals like calcium and magnesium playing a role.

A lower value can lead to stagnant plant growth, while a higher value easily leads to limescale deposits on your oxygenating plants. Because rainwater contains no minerals, this results in a continuous decrease in the GH value of your pond. \u003cbr\u003e\u003ca title=\"GH plus\" href=\"\/en\/collections\/waterverzorging\" data-mce-href=\"\/en\/collections\/waterverzorging\"\u003eView our resources to increase GH levels here\u003c\/a\u003e .\u003c\/p\u003e\n\n\u003ch3\u003e KH value pond\u003c\/h3\u003e\n\n\u003cp\u003e Carbonate hardness indicates the amount of dissolved carbonate in your pond water. Carbonate is a chemical compound of calcium\/magnesium and CO2, with this CO2 component being particularly important. Oxygen-producing plants depend on this CO2 for their growth. When the carbonate hardness is sufficiently high, it acts as a CO2 store in your pond. Essentially, sufficient CO2 is produced by bacteria in a healthy pond. However, for various reasons, the production by bacteria and the consumption by oxygen-producing plants can sometimes differ. Adequate carbonate hardness can compensate for these variations, which is known as the buffering effect. An \u003cstrong\u003eideal KH value\u003c\/strong\u003e for carbonate hardness is between a minimum of 7 and a maximum of 8.5. \u003cbr\u003e\u003ca href=\"\/en\/collections\/waterverzorging\" title=\"GH plus\" data-mce-href=\"\/en\/collections\/waterverzorging\"\u003eView our resources to increase KH values ​​here\u003c\/a\u003e .\u003c\/p\u003e\n\n\u003ch3\u003e Ammonia value pond\u003c\/h3\u003e\n\n\u003cp\u003e What we measure with test kits is the concentration of ammonia (NH3 and NH4+ combined) in the pond water. What we actually want to know is the amount of ammonia (NH3). Ammonia is harmful to carp at concentrations as low as 0.1 milligrams per liter. That equates to one part of ammonia in 10 million parts of water! Ammonia is released during the fish's digestion of food. It is therefore a waste product of digestion. Ammonia leaves the fish through the bloodstream and is released into the water through the gills. Contrary to popular belief, it is not the fish's feces and urine, but the ammonia released through the gills that is the biggest pollutant in the pond. The \u003cstrong\u003eideal ammonia level\u003c\/strong\u003e in a pond is 0.0 milligrams per liter. \u003cbr\u003e\u003ca href=\"\/en\/collections\/waterverzorging\" title=\"GH plus\" data-mce-fragment=\"1\" data-mce-href=\"\/en\/collections\/waterverzorging\"\u003eView our resources to reduce ammonia levels here\u003c\/a\u003e .\u003cbr\u003e\u003c\/p\u003e\n\n\u003ch3\u003e Nitrite value pond\u003c\/h3\u003e\n\n\u003cp\u003e Nitrite (NO2-) is produced in the biological filter as a result of ammonia conversion. This is part of the nitrification process. A nitrite level of 0.2 mg per liter or more is harmful to your fish. An excessive increase in nitrite levels in the pond can pose a risk of suffocation for the fish. Nitrite has the detrimental property of binding to the red blood cells in the fish's bloodstream. This hinders the normal function of these red blood cells, which are normally responsible for transporting oxygen from the gills to the fish's organs and muscles. The \u003cstrong\u003eideal nitrite level\u003c\/strong\u003e in the pond is 0.0 milligrams per liter. \u003cbr\u003e\u003ca href=\"\/en\/collections\/waterverzorging\" title=\"GH plus\" data-mce-fragment=\"1\" data-mce-href=\"\/en\/collections\/waterverzorging\"\u003eView our resources to reduce nitrite levels here\u003c\/a\u003e .\u003cbr\u003e\u003c\/p\u003e\n\n\u003ch3\u003e Nitrate value pond\u003c\/h3\u003e\n\n \u003cp\u003eThe final product of the nitrification process is nitrate (NO3-). When the conversion of ammonia to nitrite by the nitrifying bacteria in the biological filter takes place, nitrate is ultimately formed. Compared to ammonia and nitrite, nitrate is considerably less harmful. While ammonia can be toxic from as low as 0.1 milligram per liter and nitrite becomes harmful above 0.2 milligrams per liter, nitrate only becomes a health problem for fish at concentrations well above 200 milligrams per liter. Although fish can tolerate quite high nitrate concentrations, we strive to keep nitrate levels below 50 mg\/l. Many koi hobbyists maintain an upper limit of no more than 30 mg\/l. Nitrate levels above 50 milligrams per liter create an additional risk of algae explosions, which we want to prevent because they are unsightly. Furthermore, these algae can cause slime on plants and fluctuate the pH level. \u003cbr\u003e\u003ca href=\"\/en\/collections\/waterverzorging\" title=\"GH plus\" data-mce-fragment=\"1\" data-mce-href=\"\/en\/collections\/waterverzorging\"\u003eView our resources to reduce nitrate levels here\u003c\/a\u003e .\u003cbr\u003e\u003c\/p\u003e\n\n\u003ch3\u003e Phosphate value pond\u003c\/h3\u003e\n\n\u003cp\u003e Phosphate enters our ponds through koi food. Just like nitrate, an excess of phosphate can lead to excessive algae growth. Besides being aesthetically undesirable, excessive algae blooms can suffocate our ponds and lead to sharp fluctuations in pH. This is particularly problematic for carp, as they are sensitive to it.
