DrTim’s Aquatics AquaCleanse for Freshwater Aquariums – Tap Water Detoxifier: Dechlorinator & Ammonia Remover for New & Cycled Fish Tanks 16 oz.

To everyone purchasing this and saying it doesn’t work, it does work. It’s not an overnight thing. It took me at least a few weeks to begin getting nitrite. Ammonia is turned into nitrite in one day now. Waiting on nitrates to take care of nitrites now.

Started 3 29 gallon tanks for a research project in biology.Tank 1: Plain Water with ammonium chloride as ammonia source.Tank 2: APIs Quick Start with ammonium chloride as ammonia source.Tank 3: DrTim's One & Only with ammonium chloride as ammonia source.Ammonium Chloride was purchased from Amazon (DrTim's Ammonium Chloride Solution for Fish-less Cycling). Each tank was prepared with a standard dechlorinator (It is important not to use any product that binds or "locks" ammonia, as it is required for the cycle to progress). Water was allowed to rest for 24 hours, filters and heaters running, temps set to 80.5F, 30 LBS of standard gravel in each tank. Each tank received an initial dose of ammonium chloride of 29 drops (one drop per gallon), which raised ammonia to ~2.0 PPM.Caveats: If you use an API test kit, you will likely see about half the expected ammonia concentration. The test is not accurate at low levels, and does not measure the type of source used as well as other master kits. Be concise with the dosing and you are fine. You can use a Nutrifin NH3/NH4 test or other high grade ammonia detection kit that measures NH3 and NH4. Do not adjust water parameters or add water for several days. If you must adjust water parameters, do so slowly. Water should only be added if it has been allowed to rest after 24 hours once treated with dechlorinator.Results at 6 days:Tank 1: Barely detectable amount of ammonia reduction, zero nitrites, zero nitrates.Tank 2: Some reduction in ammonia, zero nitrites, ~20PPM nitrates.Tank 3: .50 PPM Ammonia, zero nitrites, 50 PPM nitratesTank 3 has had one water change already, and is ready for the second due to rising nitrates. It is processing enough ammonia at this point to equal ~11 inches worth of fish. Ammonia has been added to this tank daily to sustain the cycle, as fish were never going to be introduced. I will be adding fish to this tank however, and reducing ammonium chloride dosing. Decided to keep this tank.Myth 1: There are many posts on the Internet about fish-less cycling. Many of which suggest the use of off-the-shelf ammonia that you find in your local grocery or hardware stores. While some of these sources might be safe, most are not. The ammonium chloride is cheap, and will cycle many, many tanks. Consumers are generally unaware of the fact that not all ingredients need to be listed on products not intended for human consumption. Therefore, they see water and ammonia listed on a label and assume there is no surfactant in the off-the-shelf product. This is simply not the case. Most of these products do in fact contain other ingredients that are not safe for fish, and will destroy the bacteria needed for the aquarium cycle. This can be seen in one of the other reviews. The result was, the tank did not cycle as anticipated. If you want good results and have gone to the expense of purchasing a bacterial additive, spend the extra couple of dollars and get a pure source of ammonia.Myth 2: Some postings on the Internet suggest that these products use terrestrial strains of bacteria. All nitrifying bacteria need soil or other surface. Therefore, all can be considered terrestrial. They are commonly found on the bottom of lakes and streams. Our filters and substrate mimic this environment. While evidence in my experiment suggests that not all products are created equal, some products do work -- and work exceptionally well.Myth 3: The cycle will crash because it isn't the right bacteria. Fact: If the bacteria were unable to sustain, we would not see the substantial growth noted in tank 3. In order for the ammonia to be processes and nitrite to nitrate, a large colony has to exist. Once these bacteria undergo binary fission (how they multiply), there is no logical argument that would support this cycle failing. If you have an environment where they will multiply, that will continue until there is no food source. Any crashing would be the result of that food source not being adequate for the colony. Another possible source of crashing, high nitrates (more than 50-75 PPM) as this will kill the bacteria. It is also possible that once the cycle begins to establish, that the consumer adds too many fish before the colony is large enough to sustain.If you opt for fish-less cycling, use a pure source of ammonia (ammonium chloride). If you opt for fish-in, make sure you do not use an ammonia binding product to dechlorinate the water. Let the water rest for a full 24 hours before you add fish and the product. You may test for ammonia/nitrite/nitrate -- but only adjust your parameters if the results show >2.0PPM Ammonia or >50PPM Nitrate. Other than that, leave it alone for at least a week. If you do need to reduce any of the parameters via a water change (25%), fill your bucket the day before and add your standard dechlorinator to the water and let it rest for a complete 24 hours before adding to the tank. Keep your filters wet at all times (bacteria will die).I consider this product a 5-star purchase. If you have any questions, please don't hesitate to ask.

I was trying to cycle my months with just ammonia drops for months. Bought this and my tank finally cycled.

Dr. Tim’s Aquatics Freshwater One & Only Nitrifying Bacteria has been a game-changer for my new fish tank. This product has exceeded my expectations in various ways.Setting up a new aquarium can be challenging, especially when you’re trying to establish the right balance of beneficial bacteria. Dr. Tim’s Aquatics One & Only made this process a breeze. It quickly kick-started the nitrogen cycle, allowing me to introduce my fish sooner than I expected.Not only did it facilitate the establishment of a healthy biological filter, but it also acted as a disease treatment. It provides added protection for my fish by removing toxins and promoting water clarity.I particularly appreciate that this product is eco-friendly, which aligns with my commitment to responsible aquarium maintenance.In conclusion, Dr. Tim’s Aquatics Freshwater One & Only Nitrifying Bacteria is an exceptional product for anyone with a new fish tank. It’s efficient, eco-friendly, and a true lifesaver for both your fish and your peace of mind. I highly recommend it for any aquarium enthusiast.

Beginning to cycle my 20 gallon fish tank. Everything working properly.....filter, heater, gravel, air pump, PH level, Ammonia level . After 14 days I emptied an entire bottle of Tetra Safe Start plus.....After waiting patiently for 16 days....not a sign of nitrite. Then............I emptied a bottle of Dr. Tim's One and Only Nitrifying Bacteria into the tank. Six days later, still no sign of nitrite. These products do NOT work. Update: After 24 days since empting Tetra SafeStart Plus....no sign of nitrite; after 18 days since emptying a bottle of Dr. Tim's One & Only nitrifying bacteria...not sign of nitrite. Don't waste your money!!! Update: Even after using this product and Tetra Safe Start my tank took 7 weeks to cycle. Don’t waste your money!!

I am not fully prepared to say this product did not work. Ammonia levels stayed the same after dosing with the companion ammonium chloride product from Dr. Tim's. After about 6 days i saw the ammonia budge ever so slightly, but no nitrite. No nitrate.PH plummeted and TDS soared. Fungus bloomed off my driftwood, and brown sludge was starting to carpet my beautiful substrate. The glass slimed up and I was getting frustrated.But I am experienced enough to know these things happen. I adjusted my PH back up to 7, reduced the lighting, and did a small water change. A few days later, ammonia down a tad again, almost unperceptible on the API test. I excitedly checked nitrite.....hmm none. Okay, how about nitrate??? 2 minutes of shaking later......I could swear it was registering some. Not yellow but not orange either.IDK maybe I am looney. Maybe they buggies just grew up from my tap. Maybe Tim's is great.I honestly have no idea.Maybe it did work super great, it's possible.From my experience there is usually a stall in the nitrite faze where you have to adjust parameters to get things moving again.Never seen a fast forward to the end game.Who knows.I loved reading all of Dr. Tim's articles over the years.I have a hard time believing that he is not genuine about his products and their effectiveness.In this world of instant gratification some things just can't work faster.

Stuff works good

Not sure about this stuff as recommended dose first time 2 fish losses so been using lesser dose.

It didn't start working on few first days until after doing a little bit of research that I realized I needed some nutrients in my tank to provide enough energy for the bacteria to reproduce. The problem is my case was lack of enough phosphorus and magnesium in water. So, check your local water for traces of these elements if your fishless cycle has stuck and then add pinch of ground fish food into your tank in case of lacking of them in your fish tank water. Check your fish food to make sure it has these two before doing so. If you need more information, search for fishless cycle phosphate block and you'll find more information on this.

Not sure what's in this liquid to make it that Blue color I thought it would be clear. Secondly it doesn't come sealed like most Tims products, at least my 4 oz bottles were not sealed other than the cap... I don't feel very comfortable with that plus i feel like it didn't do nothing for my water quality.

Great product, fast delivery
