There are many myths about the water in which aquarium fish live. 7 is neutral, above this up … So I know there is a lot of these kh/gh threads and I've even had some more general ones before, but what is an ideal kh/gh to aI'm for in a planted tank? Most plants do extremely well with a lower KH, so as you can see you're pretty lucky. We recommend not to adjust KH, unless absolutely necessary. I have thought about purchasing the API water pillow, but I’m not sure if I want to go that route as it requires aquarium salt to “recharge”. Aquarium Temperature, pH, KH and GH. The first and possibly most important factor to consider is tank chemistry. I believe it to be the ideal range, but GH doesn't seem to matter as much.-John N. I mix my ro, so I can adjust it to the best parameters.Slowly over a month or two obviously, but I'd like to get in a good range now that I'm getting my water clarity and composition really dialed in. Freshwater Parameters The following chart provides acceptable water parameter ranges for different types of freshwater aquariums, brackish water aquariums, and ponds.The water parameters listed serve as a general guideline for maintaining each specific type of aquarium or pond. If an adjustment must be made, it is critical to make slow, incremental changes. A look at pH PH is the most common area hobbyists have issues or require adjustments. Calcium is vital for neurological functioning, and magnesium is an important co-enzyme for cells and is necessary for biological functions. Different proportions of each can be used to get the correct KH/GH balance dictated by the fish and plants in the tank. This guide paves the way to easily adjusting your pH, KH, GH and other parameters. It’s dangerous to the fish to “chase” pH with chemicals. GH (General Hardness) General hardness or “total hardness” is a measure of the magnesium and calcium in the water. Baking soda will increase KH, hence it will increase pH. Many first-time plant keepers are surprised that “ideal” tank parameters for fish aren’t necessarily “ideal” water parameters for plants. KH: 6 (100ppm) GH: 11 (200 ppm) Tap. pH is a measurement of the acidity or alkalinity of the aquarium water. Some of these myths are: At least 50% water changes should be done once a week. This is a range that I've kept plants at. A simple solution is to replace some of your water with distilled water. General hardness (GH) is comprised mostly of calcium and magnesium, plus trace amounts of other minerals. KH 6 (100 ppm) GH 10 (~200 ppm) I know I can use RO/DI water, but this is a bit more than I want to do (although I can if there is no other viable alternative). Distilled water has a KH of 0 and therefore will lower the KH. https://www.2hraquarist.com/blogs/ph-kh-gh-tds/gh-explained 4. A KH of 70 ppm and less, will result the pH crash. Africans are most likely to appear vibrant and colorful in aquariums with a general hardness ranging from 160 – 320 ppm (parts per million) or 9° – 18° DH (“Deutsch hardness”). Two teaspoons (about 4 grams) of calcium carbonate (CaCO3) per 50 liters of water will increase both KH and GH by 4 degrees. Ensuring appropriate water parameters and environmental requirements is fundamental to reduce tank mortality. GH and KH are not a problem for most plants, unless the KH is so high that it makes the pH greater than 8.0. KH: 3 - 6 degrees. GH: 4-10 degrees. Both GH and KH are expressed in equivalents of CaCO3 (A multivalent cation is a positively charged ion with two or more positive charges, ie, Ca++, Mg++, Al+++, Fe+++) What most people don’t realise is that the aquarium KH test kits don’t actually measure KH, but Alkalinity instead. Currently I'm sitting at 7.5ph 6 kh 12 gh. At that point it starts to interfere with the absorption of iron.
