freshwater fish question...

[The Mermaid Queen]

Anyone know of a freshwater aquarium test kit that is similar to the TF100, inasmuch as you look for the color change for the endpoint as opposed to comparing to a card? I'm currently cycling a tank that seems 'stuck' and I feel like NONE of the colors ever match my samples....
What do I even call the TF100 type tests so I could do a search?

TIA!

I use the API aquarium test kit for both fresh and saltwater. It is fairly accurate. In addition, I have an aquarium controller that monitors temperature, pH and salinity.
