What is the Ideal GH Level for Aquariums? As with KH, GH is measured in dGH (degrees of GH) and ppm. Ideally, freshwater aquariums have a GH between 4-8 dGH (or 70-140 ppm). All animals need some minerals, but certain fish like livebearers, goldfish, and African cichlids prefer higher GH levels.

Aug 29, 2024 · Growth hormone (GH) is one of several hormones produced by the pituitary gland in your brain. It’s also known as human growth hormone (HGH) or somatotropin. GH plays a crucial role in human...

Aug 15, 2020 · How to raise pH, GH, and KH? In order to raise your Ph, GH and KH and harden your water, I recommend using crushed coral either in your substrate or in a filter media bag in your canister or hang on back filter. I recommend starting with one pound of crushed coral for every 10 gallons of water.

Dec 20, 2016 · If GH = 45 and GI = 61, to find the length of HI, we assume that the points G, H, and I are collinear, with H lying between G and I. This is a typical problem about finding the distance between points on a line segment. To find the length of HI, HI = GI - GH. Plugging in the values we have, we get: HI = 61 - 45, which simplifies to HI = 16.

Nov 5, 2021 · Water general hardness, or GH, is the concentration of calcium and magnesium ions in a freshwater aquarium. GH is usually determined by your water source, but can be adjusted with additives. General hardness is important for the muscle development, organ function and breeding of certain fish species.

Jan 20, 2025 · GH, or more specifically calcium, is important when keeping shrimp and crustaceans. Aquariums with soft water plants typically have GH values as low as 1-3 dGH, and most soft water plants grow well in this range. While very hard water tanks can have GH levels in the 20+ dGH range.

Feb 25, 2025 · What are some effective ways to lower GH and KH levels in an aquarium? Popular methods for reducing GH and KH levels in aquarium water include using reverse osmosis (RO) water, adding peat moss or driftwood to the aquarium, and diluting hard water with soft water.

Jan 24, 2022 · Human growth hormone (GH) is a substance that controls your body’s growth, but what happens when your body does not make enough? Learn more about growth hormone deficiency, including the causes, diagnosis, treatment options.
