You don't need to start all over. You simply go to your local aquarium shop or Petsmart and go to aisle with the fresh water conditioners. You will find lots of 'em like this
one, for example. They all work about the same way, and buy whatever your wallet can tolerate.
Now, you simply need to calculate what the gallonage is your pond and then add the appropriate amount to use. Every time you add water, you need to figure out how much you've roughly added and put more water conditioner into it. If you have a small pond, you might be able to get a 5 gallon bucket and use that to pour your water in and will give you a measuring device.
If I were you, I would let the water cycle at least another 2-3 weeks since you've added the gel. You should buy some water test strips while at the pet store to get a good read on your water. If it looks good, then I'd buy two cheap feeder goldfish at the petstore. They are usually around 27 cents, and these test fish are called "canaries" in the fish world, because you are using them to see if your pond is safe enough to sustain fish yet (same way coal miners tossed canary birds in a mine before they went in...to make sure there was oxygen. If the canaries died, the miners did not go in).
If your water looks good and those two fish survive, you can begin to slowly introduce fish to the pond. I would not buy them all at once. Maybe try one every week of two. I usually quarantine my fish for 3 weeks in a separate tank, but I'm not sure if you have the capacity to do this. If you are unable to do this, I would go slow with the introduction of each of your fish and make sure you take a good look at them up close before you buy to ensure they don't have white spots, body/fin damages, etc. Have patience. I know that you probably want the instant effect of a stocked pond--but taking things slowly will guarantee you success and some live fish.
You don't mention how big your pond is, or what type of fish you are aiming to get. If you give us that info, we might be able to make some suggestions.
