Does anyone us a Pure Flow RO/DI system? Are they any good? Or should I buy on used and get a good membrane?
One last question, Is just an Ro system ok? Or is the DI part absolutely nessisary? I want some clams and a few sps so I want to make sure my waters good. Also feel free to reccomend any other brand you think is good thats 100-150$ and it doesent have to output more than 25gpd.
