Pro Shrimp's comment: Liquid Test Kits are more accurate than the common test strips and enable you to do more tests per package.

We stock refills as well!

• Recommended level for oodinium treatment: 0,3 mg/l Cu
• Accurate test for determining the copper content in freshwater and saltwater tanks. Range of values:< 0,1; 0,1; 0,2; 0,3: 0,45; 0,6; 0,8; 1,2; 1,6 mg/l.
• Can also be used to check tap water, which should not contain any copper.
• Helpful in administering medications and preparations containing copper, as the copper content should never exceed 0,3 mg/l, whilst insufficient doses will not result in a cure.
