Hi everyone, our pool is about two months old, it is 7.5k gallons and we have a spa. My question which I may be over thinking has to do with using trichlor. I have seen many folks say trichlor should not be used or is not preferred. Why would a pool builder install a Fusion 2 that uses trichlor if that is not a good method to handle algae? Should I consider switching to an SWG? If I have to change water in the pool due to high CYA levels every five or so years that does not seem so bad to me with a smaller pool like we have? Would like to get some feedback on this issue as I think I am really over thinking this.
