Got a Aqua Clear filtration system at mom's house. Looking to save some extra bucks on gas and trips to LFS. I tried to contact them personally to get a definite answer on there filtration system, but I was given a vibe that no one wants to talk to me cause I'm not a new customer purchasing a new system. (sucks!!!) So what do you guys think I should do or upgrade to get DI.. On there website it claims to be an RO system. Any advice and opinions on this system would be great.. thanks again
