TDS is a very important water parameter measurement especially aquarium tanks with shrimps or sensitive fishes. It is also an important measurement for breeding purposes and for growing aquarium plants.

TDS which stands for Total Dissolved Solids, measures all types of dissolved solids which include the components of water hardness (GH) such as Magnesium and Calcium as well as KH component such as bicarbonate.

In a simple form, TDS is the total dissolved solids of GH + KH + Nitrate + Nitrite + Chlorine + Other Molecular Compounds + Dissolved Organics 

Aquarium fertilisers, dead plant leaves, waste from fish or shrimps, water conditioners, water hardness (GH) and PH / KH buffers all increase TDS which is why it is important to measure TDS.

For planted aquarium plants, Aquarzon recommends the TDS not to exceed 500, preferably less than 400. When TDS is too high, it reduces water clarity and negatively affects aquarium plant growth (as less light would penetrate through the water column which means the plants on the base would have less available light to perform photosynthesis).

For shrimp tanks, we recommend a TDS reading of 100-250. If TDS is too high, it can negatively affect shrimps and shrimps are stressed, it can reduce their breeding rate and affect their immune system. 

For fish tanks, the recommended TDS reading is based on the fish type. In general, the TDS reading should not be too high as it can cause breathing problems and also cause other issues. If you have seen a fish that dried up, you will realise that the body of a fish is mostly containing water. As per the concept of osmosis, the aquarium water with very high TDS will pass through the fish (if the fish has water with lower TDS) until the TDS level equalises. This process affects the fish blood PH and the immune system. When its immune system is compromised and the fish is stressed, the fish is at much greater risk of disease.
