I'd never be able to maintain a fishroom full of tanks if I wasn't able to do large water changes (some of mine get 75 percent 4-6x weekly). I'm a believer in large water changes and plenty of clean water. If you're able to fit daily water changes into your routine, that's great though. Different things work for different people.
If you want to keep up with the large water changes, I would suggest premixing your replacement water in a Rubbermaid Brute or similar. Use a pump to circulate the water and add buffer if that's something you think you need.
I used to be firmly in the "don't mess with your water" camp, but I have very soft water here and there are certain fish, like rift lake cichlids and most livebearers, that I simply cannot keep otherwise. I've tried.
Anyway, just something you might want to consider.
For what it's worth, I have years of experience keeping rams and you know what? Even with tap water that is perfect for them and plenty of water changes, sometimes rams just die. Source of the fish makes a huge difference for this species in my experience and I would always recommend finding a breeder if possible. Makes the experience a lot less frustrating.
