Review on Senzeal Checker Aquarium Monitor Indicator by Jen Coleman

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 does not affect the display. I love the way it looks, haven't decided exactly where I'm going to hang it permanently on the tank yet, but my tank isn't fully set up yet.
