Water changes are easy mode, I'd recommend trying to solve for making your changes simpler so your willing to do them more often. The attached photo is a 3+ year old 40gal frag tank I have, don't test this tank EVER but give it a 50% water change weekly like religion. Recently had my RBTA split and the few acros recently added are growing and coloring well.
Best of luck to you. I did the no water change thing back when I started years ago, after about 6 months things went south with lots of losses. Water changes for life now, easy street.
