Is this even working?

[Saaqib_Ansari]

Not sure if I’m being silly but does this badge look like it’s working? And what if algae begins to grow on the central circle what do I do? As I know you’re not meant to touch it as there’s a film on there that detects the ammonia

Little Shake maybe?

Is that to clean the algae? Is usually the same algae you get on the glass? I had to throw the last one away. And do you think the badge is even working? Been in the tank for few days now

I had one and they are fine, as long as you didn't touch the middle with your hands it should be accurate, remember it only tests free ammonia which is what is toxic to your fish, other tests test free and other kinds of ammonia so the reading won't be the same

Many like it - I simply don’t trust it. Cant beat a standard test kit

I have the API one which always shows 0.25 so just wanted something else cheap that can tell me if it acc is that high or just issue with the test kit

Take some RODI water and test for ammonia with your API test kit and see if it also shows 0.25.

It does

So I would guess that is your zero ppm color. Frustrating, but I guess that is what we get. I use the API test, not so much for its reading, but the color change, telling me if it is going up or down.
