Also, what valve should I get? I have a Hawkeye 201 filter, it came with the tank
and I got the Topfin liquid conditioner instead of the fizz tabs

Good you switched conditioners.

Definitely take the filter out. You shouldn't use a filter in anything that small. It will only stress him out and it won't help any. You still doing 3 water changes a week including one 100%?

If you wnt to filter your tank you should get at least a 2.5g and even then I'd only use a small sponge filter. Ideally, get a 5g+ if you really want to filter/cycle.

You should measure AQ not add pinches, but a pinch shouldn't hurt. That's not the problem.
