I have a tank that was used for housing a snake. I cleaned it thoroughly (at least I thought I did) and I have had nothing but a terrible ammonia problem since. I have recleaned the tank and treated it with ammolock. No help. Please, can anyone help me. Is there anything that will nutralize this tank?

Prime or better yet, Safe

Prime
Safe

Ann do you have anything in the tank?

And at that, did you go through the proper cycling process?

Thank you for the info. Does prime and safe nutralize ammonia? Do you know why the ammolock didn't work? Thanks again, Ann

Yes, fish but I removed all decorations etc before I treated. Do you know anything that is a natural nutralizer like maybe vinegar or soda?

Yes, they do. Seachem also has an even stronger product I had forgot about called AmGuard:
AmGuard concentrate

There could be several factors at play here. (I'm not sure if there's a shelf life concern with Ammolock, for example.) Also, your test kit may even be giving you a false positive since certain types of kits will make some of the ammonia removal products release the ammonia back into the test sample.
For more info on the topic, this page has some useful info:
MultiTest: Ammonia

Also make sure not to scrub the filters or the gravel so clean, let the beneficial bacteria build up. Also consider dosing with Cycle or some other biological supplement to build up a bacteria colony to keep the ammonia out naturally.
