KH is measured in dKH (degrees of KH) or ppm (parts per million), where 1 dKH equals 17.9 ppm. Typically, freshwater aquariums should be between 4-8 dKH (or 70-140 ppm). If you need to lower the pH for animals like discus or crystal shrimp, you’ll need to decrease the KH to 0 …

Nov 5, 2021 · 3-15 dGH is the ideal general hardness for planted aquariums, depending on stocking. Water general hardness, or GH, is the concentration of calcium and magnesium ions in a freshwater aquarium. GH is usually determined …

Nov 18, 2024 · dgh to ppm gh is right around 18. I usually round it to 20 because it's much easier to do in my head. And it really isn't going to make a ton of difference. using 10 dgh to ppm would only be of by 20 ppm. not a big deal same thing for dkh to kh ppm. Yes, technically you can be very precise about it. but biology usually isn't that precise

Aug 9, 2009 · KH and GH can be measured in parts per million, or German degrees (dH). The difference is dividing or multiplying by 17.9. A KH of 75ppm is the same as 4.2 dKH. 5 dGH is the same as 89.5 ppm GH. If you want to know what hardness a fish requires, check it's recommended dH (GH/ dGH) at a reputable profile site like fishbase, and set your GH to match.

Feb 28, 2023 · The ideal GH level for most freshwater aquariums ranges between 4 to 8 dGH, although some species of fish may have specific GH requirements that are outside of this range. KH (Carbonate Hardness) measures the buffering …

Nov 23, 2018 · dGH = German degrees of General Hardness. dKH = German degrees of Carbonate Hardness. You may also see GH and KH measured in ppm (parts per million) instead of degrees. 1 German degree = ~17.86 ppm.

Apr 18, 2006 · TDS is a meter that measures the total dissolved solides. Conductivity is another type of meter that measures how well the water carries current (more dissolved solids, more current). Carbonate hardness, or the waters ability to maintain a pH (also known as buffering capacity) is the kH.

Oct 28, 2018 · Water hardness is usually measured in 'degrees of hardness' (dGH) or in 'parts per million' (PPM) PPM is also the same as mg CaCO3/L (milligrams of calcium carbonate per litre)
