listen, if you are o.k. with the money then why don't you just go to Wall Mart and buy spring water, it's $0.64 a gallon. it has no bad stuff in it and you don't have to use any chemicals. you can take all the chemicals back and get money back or store credit if you don't have your recipt. you will be very happy with spring water changes. once you get your readings normal then just do 25% of water change once every two weeks, which is like 20 gallons. if you want to boost your bacteria fast you can still put bacteria in it, it has nothing but bacteria, no chemicals, it has nothing to do with water chemistry, it feeds on waste your fish produses, thus will help you with fish tank maintenence. Note: the PH in spring water needs no adjustment, but it's lower from what you have now, so first few changes put one gallon into main fish tank every 10 minutes, so you can addjust your oscars slowly to new PH.
