I know you did some of a fishless cycle at first, could you take the fish back to the store and do another one now? Then go back and get new fish once you're done?This is the reason why people tend to recommend fishless cycles - fish-in is really boring!
a suppose i could always hang on a few days and see if the fish live or not
then if they die just go for a fishless cycle
(to start a fishless cycle would i be better off starting from scratch i.e replace my filter media, clean everything inside the tank gravel, plants etc?)
if you're going to just stop water changes and let them be slowly poisoned why don't you just take them back to the shop?! Or give them away to someone else, it's easy enough to do online. In your position, if I went back to fishless I would not start from scratch the bacteria in your filter now will give you a headstart on the fishless.a suppose i could always hang on a few days and see if the fish live or not
