Just FYI, Jon. (I'm a Jon, btw, and I'm in Cambridge, UK atm).

There is a good rationale for not adding chemicals (I realize that you're prob. starting to understand this now).
Chemicals: 1) are unnatural for fish, 2) sometimes only cover up/temporily solve problems in your tank, rather than getting to the root, 3) may completely obscure the true results of any tests that you conduct on the tank water such as KH, pH, CO2, phosphates, Ammonia etc tests and 4) can cause real havoc with the level of natural chemicals in your tank/can eventually upset balances.
I've experienced this! I thought that chemicals would solve my ammonia spike problems when I first started my tanks up, but quickly found that they just increased the number of potential problems in my tank. Now that I use only a dechhlorinator, if something goes wrong in my tank I can first check the vitals--temp, pH, nitrogenous waste etc. and if those tests come back fine, I know that there's bound to be a simple answer to the problem, such as disease (not SO simple...) or recent changes.
With chemicals in the water, you can never be sure what your problem is! You may think that you've got an ammonia problem, but you might actually be suffering from excess phosphates (phosphate buffers) contained in your pH regulator powder. The problems go on and on. Best bet... fit your fish to your water. Don't be afraid to add fish to water which is ever so slightly too acidic or alkaline for them, as long as they're slowly acclimated. Most fish (exceptions such as Discus apply) actually do fine in water slightly out of their natural range. No extremes, though. Don't keep cardinal tetras at 8, or African Cichlids at 6.5.

All things now understood about your tank size, you'll still have to move your baby guppies soon in order to keep the 15-gallon bioload down. You can think about selling them back to the store, or getting a 20-30 gallon tank for them (assuming most-to-all survive).

Hope all goes well! Good luck fording the purist, chemical-free world of fish-keeping.
