I’ve had an axolotl since October. Around the middle of April, a child somehow managed to drop an incense cone into his aquarium. My axolotl has been tubbed and I completely redid the tank (took out all the water, replaced the sand, rinsed out the filters, cleaned his hide). I’ve been trying to cycle the aquarium since. I’ll admit I didn’t really keep up with it at the beginning as I was super busy with the end of the school year. But since about the end of May/start of June, I’ve been adding in ammonia and checking the water frequently. It seems to be going okay, doing what it’s supposed to do, other than taking a long time, but I’ve only been somewhat consistent with checking the water (still have been adding ammonia in frequently though, especially when the ammonia in the tank gets low). My current issue is the nitrates. They seem super high, and even after doing 30% and 50% water changes the nitrates haven’t changed much. I can’t particularly tell what the exact readings are (am I supposed to hold the tube flush against the white cardboard, hold it slightly above the white cardboard, or hold it up to the light??) but my best guess is that just a minute ago, 12 hours after adding in ammonia, my nitrites are 0, my ammonia is 1 (held slightly above the white cardboard) or 4 (held flush against the white cardboard), and my nitrites are 20-40 (held up to the light) 40-80 (held slightly above the cardboard) or 80-160 (held flush against the cardboard). I can continue doing water changes but they don’t seem to help. My pH get significantly lowered every time I do a water change as well (I have crushed coral in a bag, but it doesn’t help if I do too many water changes). I also have an infestation of bladder snails from a live plant I bought at a store, but I’ve just now put a piece of thoroughly rinsed lettuce in the tank to try to get them to eat it so I can get rid of most of them in one fell swoop. Thanks for any advice and sorry for the sheer amount of parentheses!
 
to measure either hold the tube against the chart (make sure you are in a well lit area) or hold it against a piece of white paper.
what is your ph? crushed coral (calcium carbonate) takes time to break down, test your kh and gh, if just kh is low adding bicarbonate of soda will increase the kh and therefore ph, if both are low then using a solution such as 50% holtfreters + 0.1g/l magnesium sulphate would be ideal (whilst cycling bicarbonate of soda should be enough though).
when nitrates are high do a 50% water change (110ppm max when cycling) the percentage of water removed is the percentage of nitrates reduced, also test your tap water for nitrates as some contain them.

It has been literally five months and I am so fed up with the tank. I want to get it done because I feel awful for tubbing my Axie for so long but it’s just refusing to work. I haven’t tested my full parameters in a while, but my ammonia has decreased from 2 to .25-.50 in 36 hours from yesterday to today. I did water changes for the nitrates and it did absolutely nothing. My pH is low and I’ve heard of using baking soda to fix it but I have no idea how to do that, and I don’t currently have the tools to test my kh or my gh. I am at my wits end and am debating removing all of the water I can and just trying to start from scratch. I am also currently being invaded by snails, which I’ve been systematically killing off. I apologize for my rant and I appreciate all you’re doing to help me, I’m just very frustrated.

The axolotl, however, seems to be doing fine. He eats well and he swims around his little tub. He seems perfectly content, but I want to be able to give him his tank back and I want him to have a bigger place to swim around. I need literally any advice you have, please and thank you.
 
Hello,
You say nothing about thé foot you give to your axolotl (type, amount).
Some food like pellets contain various compounds which are not all digestes by axolotls, but could explain snails invasion
 
sorting the ph out will help with the ammonia issues.
try adding 0.1g/l bicarbonate of soda (1 teaspoon per 40 litres), bare in mind your gh may still be lacking.
plants and chemical filtration ie.. zeolite will help remove excess ammonia.
