I just have a couple of softies and one LPS. I already decided to not screw myself over by going cheap on the water. I've been very patient in setting up my tank and don't want to risk all the work because I wanted to save a little money. I may look into my own RO/DI unit down the road but for now I only spend 5 bucks a week roughly changing the water.
