We recently purchased a Dolphin Oasis Z5, and the warnings instruct us not to use it when FC exceeds 4 ppm. This seems unreasonable to me, especially when our pool has CYA of 97, necessitating a higher minimum of FC to prevent algae.
(We just moved into our house and are first time pool owners. At the start, our CYA was 140, so we are making improvements...)
Does anyone have any insight as to whether it would be okay to use our Z5 at higher levels of FC? Obviously, we won't put the Z5 in the pool while SLAMing, but 4 ppm just seems like a very low tolerance level for a pool cleaner.
