TDS meter aquarium

For maintenance of prawns and some fish in aquariums is very important to control the TDS, total dissolved solids, then to a high value will not achieve long-term maintenance and reproduction.

I bought mine at this online store, cost me about 10 Euros.

Works great, now I mix tap water with reverse osmosis water when needed and I control that my tanks are fit for the shrimps.
