On what scale are those KH and GH readings and what do you use to test the water (test strips or drops)? 4 to 6 sounds like german scale, but just double checking as there are couple different scales used and they are very different when it comes to numbers. Though 0 is very very low on any scale. Do you have a water softner connected to your water source?
Short answer to are GH and KH important, yes and no. Most fish are not too picky about KH and GH, some species are. Bettas are pretty hardy and tolerate wide range. So while it's benefical for them that there are some minerals in the water, they aren't overly picky on amount. Though 0 does not sound good. As for KH keeping the pH stable, it's true, but not always so simple in practise. Raising KH can raise the pH, but will also depend on are there compounds present that could affect the pH one way or another. Raising GH technically should not alter pH.

I've been using the API 5 in 1 test strips. I wasn't looking at the scale on the packet when I made that post, I was looking at a website so I think you are right those weren't american standards. I looked up a conversion table, so my water is between 0-30 ppm for GH and 0-40 ppm for KH.
Basically I've been using filtered tap water, let it sit with conditioner for 30 minutes, then I test it before putting it in the tank. When I test it, KH, GH, N02 & NO3 are all very low (since I guess its meant to be drinking water, there is not many large particles in it) I checked my unfiltered tap water and GH is 120-180 ppm even after conditioning. I forgot what KH was but I believe it was around 80 ppm. That seemed like a huge leep from 0 so I don't want to shock my fish with sudden change in water quality.
Is it worth investing in products to raise my KH and GH at the moment? My fish seems really healthy and happy so I don't want to upset him too much with water changes.
