Aquarium Kh Chart

Measured your kh then see how much you need to reduce the ph to get your target co2 ppm.

Aquarium kh chart. An aquarium with a low kh level 50 100 ppm mg l will tend to be acidic. An aquarium with a very low kh. Read on to find out how to read ph kh chart correctly.

Carbonate hardness kh also known as alkalinity is the measure of carbonate co 3 2 and bicarbonate hco 3 ion concentrations dissolved in freshwater or saltwater. The ph kh chart is often used to get a reading of co2 levels in the tank. Warning kh may not be entirely carbonate hardness.

Kh is measured in dkh degrees of kh or ppm parts per million where 1 dkh equals 17 9 ppm. However many folks go about this the wrong way. What are the effects of kh and ph in a planted aquarium.

This chart shows the dissolved carbon dioxide value of water based on the measurements of carbonate hardness kh and ph which can be easily measured with a test kit. Typically freshwater aquariums should be between 4 8 dkh or 70 140 ppm. Ph is a measurement of the acidity or alkalinity of the aquarium water.

Medium range 4 6 kh poecilidae 8 10 kh african cichlid 20 kh salt water fishes 10 15 kh. If you need to lower the ph for animals like discus or crystal shrimp you ll need to decrease the kh to 0 3 dkh or 0 50 ppm. If you plan to have plants inside of your tank be prepared for constant changes in your ph levels.

Plants can also be beneficial to your water by acting as a natural buffer as well. The gh value represents the to tal har dness that is composed by the temporary hardness indicated by kh and the permanent hardness comprising sulfates nitrates chlorides and all other salts dissolved in water. I have been trying to lower the kh at the advice from the aquarium shop to make the water ph better for the neons by doing 50 50 distilled water tap water changes every fortnight over the past 2 months but only got down to 8 0ph and then the guppies started to get fin rot in past 2 weeks.
