Stress Zyme Problems
So I have a black moor goldfish and a shubunkin goldfish in a 37 gallon tank. We got them at petsmart and we had an alarmist associate (If you don't ______, your fish will die!) who told us to get live bacteria to put in the tank. She recommended Stress Zyme. We bought a bottle, and put two cap's worth into the tank like she said, and now the tank and the water are getting much dirtier, much more quickly than it normally would. I'm even noticing a bit of a smell coming from the tank. Is Stress Zyme really necessary, and how often should I clean the tank if I keep using it?
What exactly do you mean by the water getting much dirtier? Do you mean cloudy? Or detritus on the substrate? How long has this tank been running, with the fish?
While waiting for those answers, some background. Are you knowledgeable on the nitrification cycle? Briefly, fish release ammonia through their continual respiration, and ammonia is highly toxic. Bacteria establish in the aquarium that take up ammonia. These bacteria produce nitrite, another form of nitrogen which is also highly toxic, and different bacteria take up nitrite and produce nitrate. Nitrate is also toxic, but less so, and it can be controlled by weekly partial water changes, live plants, and not overstocking or overfeeding. This is the nitrification cycle, and it can take from 2 to 8 weeks for this to establish; various factors affect it.
The clerk was basically correct in saying that you needed to add bacteria, what we term seeding the tank, which will get the cycle going faster. Bacterial supplements can help with this. Here we come to the StressZyme. I have not myself used this product, but I have used other bacterial supplements. I cannot say if StressZyme is comparable, but it can't do any harm at this stage.
Do you have a test kit for ammonia, nitrite and nitrate? The API liquid tests are reliable, and you can get these three plus pH in the Master Combo kit.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
The water has been getting cloudy, and the tank has been running for about 2 1/2 weeks. One thing I don't understand is why this is so necessary with goldfish. I always thought cycling was something people do for tropical fish.
And as a result of that last sentence of what I just posted, I don't know a lot about cycling because I never felt it was necessary for goldfish.
Goldfish are among the largest waste producers of any fish. And all tanks need to be cycled. If you haven't made a water change yet, I suggest you do so asap - a large one - around 75%. If you do not have an API liquid master water test kit, you should also get one asap so you can monitor the Ammonia, Nitrites and Nitrates in the tank. Ammonia and or Nitrites that approach .50ppm are toxic to your fish and WILL cause illness and or death. Nitrates that exceed 20ppm can also cause issues. The only thing to do to get rid of those toxins is water changes. Perhaps daily while the tank is cycling.
Please read the stickie on cycling with fish in my signature line.
You should also google both of your species of fish for their profiles and read all you can about them so you can care for them correctly.
And I HOPE the fish store sold you water conditioner to remove the chlorine from your tap water.

Cycling is definitely necessary for goldfish.
Does the smell seem to burn your nostrils a little? It could be ammonia. Cloudy water is often associated with bacterial blooms in response to elevated levels of nitrogenous wastes.
