Sorry SP, have to go with Brad on this one. For such an expensive hobby its just not worth the risk to introduce phosphates, Chlorine or any dissolved solids. You don't buy a brand new BMW sports car and then fill it with regular gas so why would you put unpurified water into a reef system? Besides, it doesn't "destroy" or make the waste water unusable so there are many applications for RO waste.
