I do not know the scientific answer to this question but my experience with cartridge filters was horrible. I had my inground 20x44 pool installed in 2000 (this was not my first pool). I started with a Hayward cartridge system and chlorine. The cartridges required frequent cleaning due to pressure rise and replacement after 1 season which is very expensive. Nothing I did seemed to work but I stuck with them for 3 seasons. I finally ditched the cartridge system due to the crazy cleaning required and moved to a sand filter (had this on my previous pool) with Zeosmarte media along with an Ecosmarte ionization system. I am starting my 5th season and have had very good luck with it. It took 1 month to get the system initially started up and working but my water has never been cloudy.
Factors to consider: I live in Wisconsin and have a relatively short swimming season (4 months). I also have a vinyl lined pool. I am on well water with very low iron and TDS. I just opened my pool last weekend. Water was crystal clear - PH was at 7.0, copper was 4PPM, calcium was above 450ppm. Just as I had left it in the fall when closing it. If this year is typical, as it has been for the last 3, I will not have to adjust PH as it has always remained rock solid around 7.0 and I will only have to ionize (add copper) midway through the season and again at the end of the season before closing.
I am not trying to sell the Ecosmarte system I am only giving my experience with it. I would also be thankful for any links to the scientific reports stating that this system in fact will not control algae, bacteria and viruses in my pool. As I said previously this is the first system which allows me to remove chlorine from my pool entirely. I have been maintaining a personal pool for 19 years now. Anyone that says you do not "notice" or have any side effects from a properly maintained chlorine pool is just wrong in my opinion. Will it be properly sanitized and algae free. You bet. But I can attest to the fact that my family and I have all experienced side effects from chlorine no matter what the ppm. It appears to be a tradeoff no matter which way you decide to go.
I also agree that Ecosmarte, or any other method of water treatment, is not for everyone. Every water supply, climate, pool contruction is different. It may not work for every situation. You do however, tend to hear more from people that have not been able to make it work than those that have.
