Tank cycling is doing my head in!

I have had my tank going since mid feb. I am cycling with my Axolotl in it. I started with daily water changes, took sometime to fix the temp (bought a chiller).
My problem is my readings are still all over the place Nikki and I have been racking our brains to fix the problems as they come up.
At the momet palliachi (axie's name) has in a 70 litre tank:
A chiller set to 18 degrees Celsius
A canister filter with a pouch of something Nikki told me to put in it...(name?)
A hob filter
White aquarium sand
An air pump with air curtain "stone"
A hide
A bridge
A rock decoration
A plant on driftwood
2 rocks that I'm attempting to attach java moss to with hair nets
5 surviver guppies (had about 30+ in the beginning but he has eaten the rest)

Reading were ok for a week or so daily with water changes. Then went to every 2nd day testing water before the changes.
Nitrate was high for a little while but that came down with 36 litre change.
Today nitrite is really high.
What do I do? I'm starting to lose hope for him and his tank.
He is fed earthworms when he eats. He tends to poo every 2nd to 3rd day.
Help please.
Hopefully a photo is attached. This was taken when the 36 litres was out.

I forgot I use stress coat+ when changing water

The pouch in the canister is API bio chem zorb

Update: tank readings are actually perfect!

The high nitrite reading was thanks to the hubby stuffing up the tests :-/

Always good to double check a super high or out of the ordinary test reading.

Phew that the cycle is ok

This happened to my tank forever, so I finally took my little guy out and let the tank do its thing without worrying about it hurting him. It took a couple weeks of nasty test results, but it finally cycled. I just changed all of his water everyday and he was safer that way. (And I wasn't constantly freaking out about his water conditions.)

Thankfully the freaking out was due to a test being messed up yesterday.

This mornings parameter tests on this tank were close to ideal ☺
