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 😕
