Even breeders can be idiots!!
Do not think that you'll get away with never having to do a water exchange. It is THE professional standard in aquariums for maintaining or improving good water chemistry. Trying to eliminate water exchanges is pure laziness, it is a fact of life just like brushing your teeth if you want to have your teeth 50 years from now.
You did not mention what kind of filtration you have now, but if you did have inadequate filtration I can see where you think it's time-consuming. If you're interested in quality filtration that will (only) reduce the need for water exchanges, see my posts below about Ocean Clear filters.
