I have some questions regarding fishless cycling of a 65L tank I have set up 2 days ago. Please bear with me.
I set up the tank with tap water, and added an appropriate amount of Seachem Prime to dechloronate. The tank has a HOB filter and a set of LED lights (for full details of tank set, see here.
The tank has some amazon frogbit and hornwort floating around, as well as tiny amounts of duckweed. I accidentally also added in a tiny dash of liquid fertiliser NOT designed for an aquarium (see here). Will this fertiliser harm any fish I put in there in the future? Will it affect cycling? Also, will the ingredient "biuret" harm the fish? I tried looking this up to little success; all I know is biuret is a condensation of urea or something.
I live in Australia, and cannot add ammonia into the tank. Instead I popped in some goldfish pellets and cichlid pellets which I had lying around from years ago. The idea is for this to decompose and produce ammonia, to start the nitrogen cycle.
Today I went to the pet store and was advised that I need to add Seachem Stability for my cycle to go well. I have not done this. Can anyone advise me if Stability is required or beneficial for cycling?
Also, I did a quick ammonia, nitrite, and nitrate test today with an API 5 in 1 kit. All showed values of zero (I even re-tested the nitrate in case I didn't shake the bottle enough, and still zero).
Can anyone tell me why all my values are zero? I thought that nitrates should not be zero after a cycled tank. Is my tank cycled? It's only been 2 days. If my tank isn't cycled, why is my ammonia and nitrite reading zero? Are my plants sucking up all the ammonia?
One last thing is that the water of my aquarium is cloudy. Is this bacterial bloom? Algae? I've also noticed on the fish pellets a white halo of something growing on it. Is this fungus?
I've never cycled a fish tank before, and I really hope to get it right this time. I also have NOT conducted any water changes since setting up the tank. Please advise if this is appropriate.
To sum up:
- Will a urea-based fertiliser not made for aquatic use harm fish? Will the tank cycling properly with this? Will biuret harm fish?
- Do I need Seachem Stability to cycle a tank or not?
- Why is my tank showing ammonia 0, nitrite 0, nitrate 0? Does this have to do with my plants? Is my tank cycled?'
- Does my tank have bacterial bloom or something else?
- Do I need to worry about white fuzz around my decomposing fish food?
- Do I need to do water changes for this fishless but slightly planted cycle?
I can't add images at this time for some reason and Stack Exchange isn't letting me add more links which is frustrating. I do have photos to show though if anyone will find them useful!
P.S. I'm planning on putting a betta in there and possibly some tank mates once things are established.
