Hello Aceigga and Welcome to Fish Lore.

Some great tips and suggestions by Ilovee. If you can't find the AmmoLock PLUS then Amquel + is another good water conditioner for ammonia, nitrites and nitrates. Prime is great too. Once you've used the Amquel + it will detox ammonia but you may still get a positive reading during the 24 hour period. However the ammonia will not be harmful during the 24 hours.
StressZyme doesn't contain the necessary bacteria to maintain a cycle without adding it for the life of your tank. However, as Ilovee said it may help to speed it along. Tetra Safe Start (TSS)is the only bacterial additive that "may" actually cycle your tank that I am aware of. Some have had good luck with it and some have not.
Once you obtain the API (liquid) Master Test Kit and test for ammonia, should the ammonia levels be anything but 0 then I suggest daily 30 to 50% water changes until you have 0 ammonia, 0 nitrites and under 20 nitrates. With a 10g tank the water changes won't be that difficult. Add your Prime or Amquel + or AmmoLock Plus (whichever you choose) with each water change and your fish should be safe for 24 hours until it's time for the next water change.
Best of luck and please keep us posted. Glad to have you on board! I hope you find the site helpful and informative. Lots of friendly members here.
