I am a new pool owner this year and purchased an AG package which included a Nature 2 sysytem. Everything was going ok until we went on vacation and returned to green water ( I already received advise on chemistry in this forum). but I guess I'm looking for advise on if I should consider removing the N2 cartridge permanetely. This being my first pool I'm really not sure if they're good or more trouble than the're worth. I really can't say if having this system contributed to my Algae bloom but with this system FC levels are usually .5ppm (seems too low to me, but they claim that is normal with the N2). Also it has been 2 weeks and I still don't have clear water so I'm wondering if the N2 system is somehow slowing the clearing of the water. Soooo confused. Any opinions on N2???

Thanks In Advance
