Yep and quit your job, neglect your family, health, and don’t have a life. Lol I’m semi kidding but you’re giving advice that is only feasible for 3 types of people: 1. independently wealthy people with nothing but time, 2. People who breed and sell discus for a LIVING 3. People who work part time at Subway and live in mom’s basement with no responsibilities.
Yes if you change water everyday then you will have bigger fish faster. But if you keep you water parameters in check you can raise nice (not crappy) discus without the extra work. It always makes me laugh when people say there’s only one way to skin a cat. That’s false there are many ways to to this. Keep it simple and you can enjoy your discus without making the return on investment not worth it.
