yeah this is a big scarry fact. yes fish are not mature but the dry rock has tons of dead critters inside it ( large pukani) and the breakdown of them built .5 ammonia in just 3 days and thats when I added the bottle. so the unkown in that regard is how much food for the nitrogen cycle has the dead critters provided and how much will it continue....and when will it end? I can imagine that the large amount of pukani dry rock with dead stuff will be breaking down for a long time....year or more? does that sound right?
Funny thing about ammonia is you can test 90 times in a day and never change readings then do one more and it spikes off the charts, you have to see it to believe it but it can be crazy.
I think you may get away with some of this because of the large water volume and small fish but that doesn't mean it isn't spiking. You said you had saltwater fish 14 years right? So you should notice issues rather quickly and would probably do a large water change to help them breath without being poisoned LOL!
When I cycled my 12G tank it killed a fish because I didn't wait long enough, small damsel at that, the water volume just isn't there to accommodate the waste and cycling that was occurring. I do agree with the rest on the normal processes, which is IMO the right way to go. Now with that said, starting off completely dry as you had the Idea in the bottle would be to populate the tank with beneficial bacterial which no doubt is a good idea but I would of done it slightly different. One I would of boiled the rock clean after it being dry so long, purify it basically and the big difference I would of done is not add fish. I would have a large tank of water, lots of clean dry rock and nice dry sand. I would run the tank normally at that point, light cycles, skimmer temp everything else but the fish and feeding.
What would you benefit from doing this? Well you get all of the good bacteria you need and want, you have no unwanted critters algae and other things that could cause issues. My little 12g tank was started this way, took a long time to get good cycle but It has the benefits as mentioned.
The only downfall to all this is like most people they want the LR & LS and all of the critters involved, so the desired type reef setup is completely different thought process about how it is accomplished.
IMO all you can do at this point is ride it out, take notes and share your findings with us, be detailed and as honest as you can be with the information, this will be the most helpful. Also remember for every one post here you have 50 users not posting here but just reading it, so everyone will have their own opinion or desire to see your results regardless of the outcome. Last thing I want is you to feel like we're ganging up on you, you are facing some very experienced people here and we all respect their knowledge so keep that in mind, your doing something and sharing, good bad or whatever it is cool to get people involved, so when you see the replies then you know your bringing in an interest!
