Interesting thread...
As to not being able to cycle a tank that small because it doesn't have enough surface area, well that is almost too ridiculous to even mention. Ignore that.
As to having too many fish to be able to get a tank to cycle - well that is about as uninformed of an opinion as the previously mentioned statement. Rubbish. Read about fishless cycling - look at the ammonia levels used to cycle the tank. They are way higher than what those little fish can produce and somehow the bacteria colony establishes itself anyway.
Cycle is nothing more than a way to cycle money from your pocket to somebody else's pocket. Worthless.
Don't bother with buying R/O water - your water isn't hard anyway. You said it was GH 60ppm? That's less than 4 dGH. If anybody told you that was hard - they are not a viable source of information. And if that person suggested that you had hard water because you have a pH of 7.6 (?) - and that same person later tells you it's raining, go look out the window before you grab an umbrella.
The most cost-effective product you can get for dechlor is Prime. Some of the others make claims of all kinds of wonderful things they can do for your fish. Ask yourself this - does aloe grow under water? (no) Then why would fish need it? Manufacturers prey on the gullibility of the general public.
If you do not have room for the Corydoras now, you should not have them now. Planning an upgrade? Great, when it is set up, buy the fish for it. Not before. Plans are great, but life has a habit of getting in the way. The fish are the ones who suffer.
Without the Corydoras in the tank, you really don't need to stress too much about the water parameters. Reality check : What do you think the parameters were like in the bowl the Betta lived in before? It is in significantly more water now, which will dilute pollutants. I'm not saying not to do water changes - just don't stress about it. The Betta will do fine. Change 50% daily with dechlorinated water. It will take time to get the cycle going. But it will happen.
