discus tank water change myths

[Jazzie]

Heard some folks say you must change water after feeding beef heart. Myth? I feed it twice a week in my 65g, FX4, and change 30% after. Fish seem fine, but it's messy.

Beef heart's just gunkier. I do 50% after feeding it in my 50g, but that's 'cause the water clouds. Regular flakes? 30% weekly's fine. Depends on your filter's hustle, really.
