Everything can be relative. Some people think it's ok to kill, does it mean it is? Let's not get off topic here.Expensive to you might not be expensive for someone else and proper husbandry for you might be carelessness and laziness for someone else as well.!
As to proper husbandry techniques trust me many here and on other boards would neither agree with mine or yours. That would make us both either right (or wrong) in what we do. Happiest Reefing!
