No there isn't I'm afraid. Tetra Safe Start will shorten the length of time you need to do the water changes but despite what the blurb may say, it won't do things instantly.
It has occurred to me while I've just been making the bed that we may not have explained something properly, something we all know but forget that newcomers to the hobby may not know.
Water companies add something to our water to kill bacteria and make it safe for us to drink. They add either chlorine or chloramine. These don't harm us but they do harm fish, and they kill the beneficial bacteria that we need to grow. So we add a water conditioner to water that goes in a fish tank. These contain a dechlorinator which removes the chlorine or chloramine so the water does not harm fish or kill the beneficial bacteria. Water conditioner has to be added to any water that is put in the tank, whether that's the water used to fill the tank at the start or any water added later on.
But there is another issue, which is what this thread is mainly about - ammonia. This is fish's version of urine. Fish excrete ammonia 24 hours a day. It is made by fish in the tank, it doesn't come in with the water out of the tap. Ammonia is removed by good bacteria not something from a bottle and we have to grow these bacteria. Until the bacteria have grown enough of them, it is our job to remove the ammonia by doing water changes. Tetra Safe Start contains these bacteria but it takes them a while to settle in and get to work.
Many water conditioners have another chemical in them which detoxifies ammonia for 24 hours, and Prime has yet another chemical which detoxifies nitrite for 24 hours. But these only work for 24 hours so we have to do a water change to get rid of ammonia and nitrite then Prime in the new water detoxifies the ammonia made by the fish and the nitrite made from that ammonia during the next 24 hours. Then we do a water change to remove the ammonia and nitrite and the Prime in the new water detoxifies the ammonia and nitrite for 24 hours .........and on and on.
