    I've not been keeping fish for too long (5 years) compared to some other forum members on here, but I've never actually used any form of deliberate cycling until my most recent tank. My personal experience is that fish can be placed straight in dechlorinated water and start dosing stability. Do water changes twice a week (once a week is probably sufficient tbh). I am aware of the dangers of nitrite and ammonia so I do test my water before every water change in the first month. There was never an instance of any detectable nitrite or ammonia. Now with my most recent tank, I tried doing a fishless cycle with ammonia and bacteria culture. I started with 2ppm ammonia and after two weeks of waiting the ammonia dropped slightly to about 1.5ppm. After that, there was no more reduction in ammonia concentration for another two weeks. I gave up at this point. The next day I drained the tank completely and placed fish straight in with new water. I'm not sure how much longer the cycle would have taken, but I'm certain that the fish food method would take much longer than starting with pure ammonia. My honest opinion is your fish will be completely fine with no deliberate cycling. The tank will cycle itself in time with the fish. I've done it with supposedly sensitive fish like a German blue rams, cardinal tetras, and otocinclus. No deaths in the first month from any fish. All otocinclus are still alive (3+ years old), and I've moved them into every new tank I've set up to eat algae. None of the new tanks have been deliberately cycled. 1 Ram dead at 2 years so probably old age. I can't remember clearly but I think 2 cardinal tetras died within half a year. Unlikely to be due to cycling issues at 6 months in. I understand the science behind cycling so I'm sure it works and is a good mechanism to prevent ammonia from harming fish. So the purpose of my post here is not to discourage you from cycling, but just to share my personal experience and to let you know that my fish are very healthy despite me never having cycled a single tank before 😁

    I realise this is an old post but just thought I'd add that I've fishless cycled using ammonium sulphate from the garden centre; I just dissolve some in water and add it to the tank until I get to 2ppm, then top up with more solution as needed. If there's any unprocessed ammonia when fish are added, I do a 100% water change immediately before adding them. If ammonia is at 0 there's no need, but I don't let ammonia bottom out while the tank is unstocked for fear of starving the new bacterial colony. No surfactants to worry about, and the sulphate part does no harm - I've read that it could reduce pH, but haven't found that to be the case.

    As a side note: I used cloudy ammonia to cycle mine a few years ago. The amount of surfactant added is very minimal and didn't effect the process, 100% water change before adding fish (which should be done anyway) and not a problem. If the food doesn't work, give it a try. A lot of what you read are from the over cautious who never tried it and are just repeating what they read from others who have also never tried it. When doing research I didn't find one case where somebody used cloudy ammonia and experienced adverse effects because of it.

    Kick Start nitrogen cycle

    There are many things being set up when you cycle a tank and establishing the start of the nitrogen cycle is only one of them. Bacteria in a bottle, fish food or a dead shrimp actually has little to do with the state the tank will be in when it has cycled. Two small fish and some patience will establish conditions required by two small fish and nothing else will. Some people have convinced the world that cycling slowly and showing some patience is cruel but how cruel is it to put your fish into a tank full of the wrong bacteria? I used to breed 50000 tropical fish a year and have never artificially cycled a tank yet. Every one to their own I guess.
