IMO with a 55 gallon tank you should invest in a RO/DI filter. I am not sure what you are paying per gallon of spring water but it has to add up when doing water changes on a regular basis. Also the hassle of having to go buy the water and lug it in and out. I am not sure what your budget is but you can get a good RO for not that much online ($129 - $199). It would for sure pay for itself in the long run of things. If I had to guess I would say that with you using a RO/DI machine at home would produce better water quality than spring water that is sold at stores.
