Great product 5 stars because I have used this before in a different aquarium and it worked great that’s why I got another one. This doesn’t work in my current one probably because if probes.

I purchased this item I purchased this item, so that I could look through side view and see clearly to the other side. Worked great. The only problem I had is hooking to the top rim of my aquarium. I have a wide rim on my aquarium.

It did take the smell away but still not… I did take the smell away but still not crystal clear water yet its only been almost a couple off weeks still giving it a chance to see if it will

Ordering was easy… Got the product and… Ordering was easy… Got the product and installed the same day it was delivered. After a few days, my water has been clearer than it has ever been. I definitely will be buying one of these again if I decide to do another tank.

Buying more.. It works! My 40g planted aquarium was really smelly. It was a dirted planted tank (walstad) When I googled how to get rid of smelly tank the unscripted aquarium device popped up. I had heard of microcurrents used in sewer treatment plants. I tried it and I was blown away with how quickly the smell went away. Within a few days. I had been doing water changes every other day for months. After adding this device I've only changed the water once in 6 weeks. I'm going to buy more of them for my other tanks.
