Here is the really strange thing here. In 2001 I did my first fishless cycle. Because I did not know any better, I used ammonia which contained surfactants. Over the next few years as I ramped up the number of tanks and then began setting up temporary summer tanks every year as well. An I cycled all of these using the same ammonia.
Moreover, I have needed to keep what I believed were empty tanks cycled or get a new one up. In all cases they were all well planted. So I would dose the very same ammonia. On three occasions, a week or two into the every few day ammonia dosing routine, I discovered newborn fry in the tank. The first were zebra danios, the next were Pseudomugil gertrudae and the last choprae danios. I believe in two case the eggs went into the tank on plants take from other tanks as those fish were never in the empty tanks. In the third, the eggs were left behind in a planted Q tank.
I never had problems using the ammonia with surfactants, but I did a few things I believe helped mitigate any potential effects. Number one is I did at least one 35% water change a week and I also ran carbon in a filter. Finally, when the cycle was done, I did another big water change, 75% or more. My best guess is I cycled somewhere between 60 and 70 tanks this way over the years. About few years ago I switched to using ammonium chloride.
One other thing was different about how I cycled. I did not use the dose and test method, rather I employed the method that it replaced- the drops per 10 gallons. This involved adding 5 or 6 drops of ammonia to the tank every day fer each10 gals of water. When nitrites showed up, the amount was lowered to 3 or 4 drops per day. The tank was cycled when you could dose 5/6 drops per 10 gallons and get 0/0 the next day. This is a lower dosing method and my water changes and carbon may have reduced or eliminated the surfactants as an issue.
memebers should understand that I am not suggesting other people do what I have. I can not find any support for what I did from hobbyists or scientists. I know it worked, and that is enough for me. But I would hate for people to try if and have bad results. Continue to look for pure ammonia, it can't hurt. Or look to use ammonium chloride as well. If you want to try cycling with ammonia that contains surfactants, please do not blame me if it doesn't work out.
