The main problem I see here is that you're changing out your carbon filters once a month. Firstly, you shouldn't be using a carbon filter unless you're trying to clean up after using medications. You've got two HOB filters, so if you need to change out the floss filter (which shouldn't need replacing until it's literally falling apart) you should alternate doing so between the filters so you don't have all new media for both filters. Secondly, what do you mean by "bio filter"? And thirdly, adding that many fish at once can create a mini-cycle in less than a 24-hour period so you might not catch it.
1st: Im not sure if all HOB filters are done the same way... but mine contains a dense fiber filter, which contains carbon. basically a pouch of carbon that catches the large debris. it also contains a 'bio filter'. should i just cut the carbon out and leave the fiber? doesnt the carbon help out with toxins?
2nd: 'bio filter' <-> 'floss filter' ...maybe..? where most of the beneficial bacteria is 'supposed' to be. what do you mean by floss filter? lol
3rd: should the number of fish added at one time always be around 5 or so? or can you add more as your stock increases, so long as it doesnt 'tip the scales'? I know most people say you can add 50% of your stock at once. looking at it, 9 probably was a bit much. but they (the barbs) are fine from what i see. the others are notSo should i be testing for ammonia every couple hours or so?
If the tank goes into a mini cycle, how long does it take to bounce back? you said less than 24 hrs... is that always the case? So my fish getting sick and dying might possibly be from a rise in ammonia? could they last for a few days before showing signs? please elaborate!
Tell me exactly which filter you have and then I'll look it up. Sounds like it uses the same kind of filter media mine does. What I did with those was cut a slit in the bottom and took all the carbon out. It only really does a little bit of good for a few days, like when you're trying to remove the last traces of medication. Otherwise it's pretty useless. Then in the back of the filter where there were just empty baskets I put in ceramic media. Floss is the kind of whispy white filter media. And you should be rinsing out the filter, gently, every time you do a water change, or at least every other time, to get rid of the mulm buildup.
I don't like to add more than 6 fish at a time, no matter how many are already in there. Even in a 55g that's increasing the bioload by a LOT all of a sudden, so I'm sure there's always at least a small ammonia spike. It's whether your filter(s) can handle the spike with a well-matured batch of media, and that would also determine how quickly it bounces back. If your tank is completely cycled, there shouldn't be much of a wait, but it's possible the damage was done with the number you added. It also depends on the stamina of the fish. And about a bunch of other factors nobody knows about.
There's also the matter of your really high pH. Do a bit of research on the types of fish you have to see what their ideal pH should be.
