Looks great, best in aquarium test kits

Love the look, bought this to replace the control glass I had in my nano aquarium which was too big. Glass doesn't feel cheap and looks really good

Does its job perfectly!

Standard drop tester that is easy to use and eliminates the hassle of suction cups and wet hands. Make sure you place it on the opposite side of the diffuser to ensure accuracy!

I would like to know that this does not work on frame tanks!

I like the product very much. It is slim and perfect for CO2 measurement. Delivered quickly and intact. The only problem is that I can't use it :( it doesn't fit any of my framed tanks. I left it for a future unframed tank :)

  • cool product

Convenient and easy to use drip checker.

The convenience of being able to easily hang this drip tester on the rim of your tank can't be underestimated, but those wanting a cleaner aesthetic could potentially need a tank drip tester as there's still something to hang up on rim of your glass.

Designed for frameless aquariums

Designed for frameless aquariums. Didn't realize it when I bought it but it still works, just floats and can move around in the aquarium. I was having trouble balancing a planted tank and thought about adding CO2. However, since then my tank has been balanced without CO2 and I no longer constantly measure the CO2 in the tank.

Inaccurate due to positioning

I wanted to fall in love, but unfortunately form is more important than functionality. It's likely to give inaccurate results due to its location so close to the surface unless your tank is filled to the brim - a more traditional form an inch below the surface with the same liquid gives me a color that reflects actual CO2 levels . when testing. In my case, this test program became more and more yellow, regardless of the tested CO2 value.

It's really good for the price

I've never used one of these external drip testers but for the price I decided to give it a try. This piece is just over half an inch wide (roughly 22/32 inches), as previously mentioned it probably won't work on anything with a thick plastic rim. If you have a rimmed tank, you should probably go for one of the original styles that suck glass inside the tank. Due to the temperature difference outside the tank, there is actually some condensation in the pipe as you can see in the picture, but it

  • Very good value for money
  • Quality
