i'm not sure if you can call a brittle star or serpant star a cleaner, but i got one of those and a bunch of hermit crabs, oh and snails too. thats about it. i use RO water in my tank as well.
the system has been moved recently. early january, shouldn't the system have cleared it self up from the move yet? i'm doing everything that the previouse guy that owned it did and when i got it it was pretty mint!
