I think I would also tell him that if he wants you to "fix it," then he is going to have to listen to what you tell him. Otherwise whats the point. I can hear the conversation now...
owner: "My tank is ugly...fix it"
friend: "Okay...you need to ditch the U/F and replace it with sand."
Owner: "No I like the U/F....fix it."
Friend: "okaayy....more circulation...add power heads"
Owner: "No..I dont want to spend the money....fix it."
