Review: Used this to cycle my fish tank. Worked well and took all the guesswork out of the process.
Review: Dr.Tims ammonia is a great product for setting a baseline for your fish-less cycle. Sure you can go buy a litre of ammonia from the shop but then you need to do a little math to figure out the correct dose for the concentration your bottle contains. Then you have more ammonia then you will probably ever need for the remainder of your natural life. But with doctor Tim’s they have to all figured out for you and it’s consistent and repeatable as long as you can follow directions. The hardest part is waiting for your ammonia and nitrite levels to come down as your tank cycles. Combine this with Fritz 7 or turbo start and you have a fast lane to a cycled tank.

## Questions & Answers

**Q: will the packaging leak while it's shipping?**
A: Mine leaked and was almost half empty upon arrival

**Q: Is it a dropper bottle**
A: No, however they do provide a plastic dropper that works really good

**Q: How often should i use this? everyday? i've read that adding too much ammonia at one time can actually prolong cycling time so i just want to be sure.**
A: Use a liquid testing kit for ammonia daily when using this product. I kept my ammonia levels at about 2 or 3 ppm. Once the ammonia starts to decrease, test for nitrites. Keep ammonia around 2ppm until nitrates appear. Once nitrates appear, you should be pretty much done.

**Q: How many ounces is this?  Nothing in description on volume.  Dr. Tim's sells 2oz. and 4oz.**
A: I received 2 ounces when I ordered it.

*by S***R on 6 December 2023*

I have a 30 litre aquarium and am totally new to keeping fish. Having tried twice both totally unsuccessfully to cycle my tank with fish, having followed all the guidelines, I discovered you can do the cycling with ammonia ( something the fish suppliers failed to mention when I was struggling with my set up! But we're quite happy to sell me fish). I downloaded the ammonia cycling information from the code supplied with the ammonia solution. It is very informative and explains the cycling from ammonia to nitrites and nitrates very well and once completed you can then introduce your fish. The literature did say after 14 days my cycling took 23 days until I was happy the ammonia and nitrite levels were 0 each day. I then bought and introduced 6 danios...well success and very happy fish. My tank water is crystal clear, I did one partial water change after 19 days. I recommend setting up your fish tank in this way as it is so upsetting to loose fish during the cycling process. It's excellent value for money and providing you carefully follow the instructions you shouldn't have any problems.
