Use Tetra Cleaning Bacteria monthly. Add 2 teaspoons (or 10 milliliters) for every 10 gallons of aquarium water.

Review: Keeps a 3 gallon Betta & Shrimp aquarium healthy! And a 75 gallon too! - 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).

Typically, once a month is fine but it depends on a number of factors. Also, take the filter system apart and be sure to replace carbon at least monthly. Carbon will remove odors from the water that are due to metals, medications, etc. Once you have done the partial water change and cleaned the filter system, then it would be good to add this product as it will help to continue to clean up the tank for you. If added regularly, it will reduce your maintenance over time. **Q: Is this okay to use in a planted tank?** A: Yes indeed, Average Joe shopper! This is perfectly safe in planted tanks! I use it in my own planted tanks with great results. **Q: Should I put it in the filter ? Or in the tank itself?** A: Great question Desmond! You can actually do it either way, it won't really make a difference. Either way it will be circulated around the tank. **Q: Will this help dispel a microbial bloom (cloudy water)?** A: We have never had a problem with cloudy water and we have been using it for about 2 years. We also clean our filter once a week. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Keeps a 3 gallon Betta & Shrimp aquarium healthy!
