So Jack Wattley was a huge proponent of large, frequent water changes to raise good discus. He talked about water changes long before most of us understand its importance. You may be confusing that with Gabe Posada, who owns Jack Wattley Discus. Jack passed away a while ago. Gabe is an importer of discus, not a breeder. They bring in fish and turn them over as quickly as possible. Most, but not all, discus suppliers typically fall into this category.
Discus are the "tip top" of fish keeping precisely because they have stringent requirements. They're also very expensive. You may want to consider keeping fish that requires lower maintenance.
