I bought my wife a little 3 gallon aquarium. It is divided in the middle. Water cascades from the taller side to the lower side. She has it on her desk. It's pretty great! Keeping a small tank like this can be harder than maintaining a big tank. The water parameters can go bad in a second, where in a big tank you have some time before it would crash. I've kept freshwater and saltwater tanks for years. I even used to breed seahorses. So I know how important it is to keep water quality pristine for fish and other inhabitants. I use Tetra Cleaning Bacteria simply because that's what it is. Beneficial bacteria. Tetra adds some minerals too. Now this tiny tank has a tiny internal filter. It has some ceramic media and a mechanical filter pad in it. I added two tiny air stone powered sponge filters to aid with filtration. Some people will tell you that a product like this isn't necessary. That the aquariums already have a colony of beneficial bacteria in them. That what your tank has is enough. Well, I am sure that is true for some aquariums. I am just not sure that is true about ALL aquariums. The amount of filter media on this tank is small. This tank's inhabitants include: a male betta, two nerite snails, some hitchhiker bladder snails, 13 cherry shrimp and it's packed full of live plants. I can tell you that it has been pretty easy maintaining this tank. My wife maintains it well. She does NOT overfeed the inhabitants. (She used to have a freshwater angel fish tank and a big salt water reef tank, so she knows what she is doing too). The parameters are great! I do weekly partial water changes. I keep an eye on the filter media. I did just switch from the filter "cartridge" made for this filter and cut a piece of 8 layer sponge filter media for the internal filter to replace it. That will also give a home to even more beneficial bacteria. All I can say is that I am 100% convinced that this product works. Her nano tank and my 75 gallon tank are doing great! I've added a pic of my 75 gallon tank too. The water is crystal clear and the parameters are also excellent. Bottom like: I highly recommend Tetra Cleaning Bacteria. (Oh yeah, almost forgot. I used Tetra SafeStart Plus on both tanks when I set them up. I do believe that was the way to go. You cannot argue with our results).

I add this with every water change to keep my aquarium water in balance. Dosing is simple. This helps to keep the healthy bacteria in check.

PROS- I may not have bought this if I saw that it came in a bag, but I'm glad I bought it. CONS-Comes in a bag.

Keeps my water clear and fish happy! My 10 gal tank of freshwater was getting cloudy so I added the recommended amount of this and noticed the water clearing within the same day!
