Swred5 Posted May 10, 2021 Share Posted May 10, 2021 Good day! I am curious, currently use the Tetra test strip, but will be changing to the Coops once I'm in need. My question is, does the Coops turn the same color as the Tetras? The color key on my bottle got wet and the page got stuck together. I know the Coops comes with a laminated result color key, so would like to be able to use if the tests turn the same colors. Thanks for anyone's help!

Tanked Posted May 10, 2021 Share Posted May 10, 2021 I haven't ordered the Coop strips yet , so I can't answer the question. The link below will give you a reasonable representation of the Tetra chart in PDF form. http://www.tetra-fish.com/~/media/UPG/Tetra/Aquarium/Water Care/Test Kits/2013TestStripColors.ashx Link to comment Share on other sites More sharing options...
Mary Mckinny Posted May 10, 2021 Share Posted May 10, 2021 I just received the test strips and took a few to test my Tap water, the Hardness is Purple (bright purple) and all the boxes on the guide are shades of blue. How do I read this? Link to comment Share on other sites More sharing options...
