I'd say to cut down on the feedings, I don't think your snail can finish 3 wafers in that short a time. I find that wafers are extremely messy and gets all over the place. Cut back on the live feedings as well, and try to stick with flakes for a few days, re-test. Keep up the water changes to make sure ammonia is below .25 ppm. Keep extra air to combat the columnaris, and also add some salt. Melafix won't do anything against columnaris but keep it from exploding. If you're treating for bacteria i.e. columnaris, then you are also going to be hitting your biological filter as well.
How big is the tank, and what type of filter?
Cleaning the filter every week is not necessary, and if it is, then you are most definately overfeeding. I clean my HOB filter at most, one a month. Water is crystal clear, and house more than 50 guppies in the 10G. There's no need for cleaning so often.
Although I may agree that the daily gravel vacs are excessive, I wouldn't hold it accountable for her ammonia readings. Gravel vacs killing bacteria will only shift the main population of bacteria to the filter, and other areas of the tanks. The thing about bacteria is, it's everywhere. Removing it from the gravel, will only make a higher demand for it elsewhere.
I believe her problem is overfeeding, and an increased bioload so she's seeing a mini-cycle. Keep up the water changes, reduce your gravel vacs, and reduce feedings.
If you know anyone local that also has fish, offer to test his water to verify that the test kit is good.
Have you tested your tap water yet? Take 2 tests, one right out of the tap, and another after it has sat for 24 hrs.

I was just thinking...maybe I'm not rinsing my biofilter properly?
When I do my weekly 50% I take out the biofilter and I dip it in the tank water that I just vacummed out of the tank. I dip it a few times and I will take and pic off any matter that I can see (like plant pieces).

It sounds to me like daily gravel cleanings are whats killing alot of the bacteria. The feces from the fish is what produces the ammonia that fuels the growth of bacteria. So aggressive gravel cleaning isnt giving the bacterial enough fuel. What you can do is either reduce the gravel cleanings or you can scan the top of the gravel with the siphon without digging in. This picks up any garbage sitting on top and leaves the bacteria in the gravel put.
