Review: If you are new to aquarium keeping I can recommend cycling your tank using this rather than fish - 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.

Thanks** A: Yes it will be . I cycled my 350L tank and only used a 3rd of a bottle . **Q: How many drops for a 5gallon?** A: Has per the answer here http://www.drtimsaquatics.com/resources/fishless-cycling 4 drops per gallon **Q: Can I use this with the fluval biological enhancer** A: I think you can use it with any bio boost with fishless cycling - really good to have an accurate measure of ammonia - test after adding it though because the measurements I got on the one I got from here weren't that accurate - ordered a newer one - 4 drops per gallon and that was much better for accuracy. **Q: Genuine? - added to a year long cycled tank in small 0.5ppm dose and it hasnt cleared in 24 hours..hmmh** A: If your tank is cycled, we are you adding ammonia? What are you trying to clear? ## Customer Reviews ### ⭐⭐⭐⭐⭐ If you are new to aquarium keeping I can recommend cycling your tank using this rather than fish *by S***R on 6 December 2023* I have a 30 litre aquarium and am totally new to keeping fish.
