The premium Czech  aquarium company Coral-Shop is at it again, once again expanding their test kit line. This time around a Sulphate and Potassium test kit were added, and the Calcium test kit was improved. Although Sulphate and Potassium test kits are nothing new and testing Sulphate and Potassium levels  is not yet very popular outside Europe, we are happy to see trustworthy titratic test kits added to the market.  The Calcium test kit has been upgraded to speed up testing rates and to make the test easier to use overall. A set of plastic labware including syringes, tips, gloves and plastic titration containers, dubbed Consumables was also added to the line.  Pics after the break.
