Overfiltration in the levels I suggested is not wasted money, it is proven to keep the water cleaner for longer in between water changes and breaks down waste faster, keeping water clear and looking better. Its like buying a top of the line computer over a basic model, it costs more but the specs are better. Some people feel like its worth it, some dont, but just as you give your advice on what works for you, so do others, only we dont bash other people for advice that does work. Not to mention pristine water is proven to lead to faster growth, and longer fish life. Also, I do tank set ups and maintenance for people in my free time. To date, Ive never had a complaint about the extra mile I have people go to take care of their fish. Believe me I warn them that what i suggest is not the cheapest option and that I believe in optimum care. But I have gotten dozens of calls and emails back thanking me for how happy their fish are and how beautiful and vibrant their tanks look. Theres keeping fish, and then theres loving fish.
