Lycramosa Posted July 4 Share Posted July 4 I'm using the Aquarium Co-op Test strips and it gave me this light pinkish purple color for the gh. I'm not sure if that means it's high or what. I tested it twice and followed the directions by swirling it in the tank for 3 seconds and then waited 1 minute before reading it. 1 Link to comment Share on other sites More sharing options...
Galabar Posted July 4 Share Posted July 4 (edited) I've never seen that result before when using Aquarium Co-Op test strips. Interesting... 😵💫 However, I do get a purple GH color that I'm unable to interpret: Actually, now that I look at it through a picture, it seems somewhat close to what you are seeing...

nabokovfan87 Posted July 5 Share Posted July 5 It looks like 80-90 to me. I would recommend trying to have a GH/KH test kit (API liquid) on hand. It's not the most fun thing in the world, but it does make it nice when you run into issues. If you keep any invertebrates it's a very invaluable tool!

Galabar Posted July 5 Share Posted July 5 Any idea why it's light purple? Link to comment Share on other sites More sharing options...

The light purple = off the scale to the right. Demonstrated / explained in this video. Edited July 5 by nabokovfan87 Link to comment Share on other sites More sharing options...
Lycramosa Posted July 5 Author Share Posted July 5 The video was very informative! Thank you! However, I'm still getting the same results after trying the towel method. It doesn't look like there's bleeding from anything onto the hardness/GH pad, and I've tried two more times in the same tank and one in another tank with the same results. This weird light purple pink color. Definitely not a blue or true purple to really be able to tell what it is. I havent had this issue before with these strips. I believe they are the ones with the nitrate pad coming off, that samw batch, but i havent had any issues with that. I do have an API liquid test kit I can dust off. I hope it's not expired 😕 Link to comment Share on other sites More sharing options...

Those are the same colors I get each time I test. I have also considered it to be off the scale to the right. My local waterworks says I'm wrong, a chemist said I'm right. Hopefully Amazon will deliver the GH-KH test kit tomorrow and we will see. Link to comment Share on other sites More sharing options...
Galabar Posted July 7 Share Posted July 7 Should we assume that anything purple (even light purple) is on the right side of that scale (or over)? Link to comment Share on other sites More sharing options...

Yes And no. What we should do is verify things with a secondary test kit. I.e. liquid. Link to comment Share on other sites More sharing options...
