which filters do i need to replace on my rodi unit? it is a coralife one.its been a long time since i bought it and i havent replaced anything on it yet...
If you have just an RO, then the RO membrane should be changed approx. every 2-3 years depending on the amount of water you make. You really need a TDS meter to tell when you need to replace it.
The other filters need to be changed every 6 months no matter what....
ok. i dont have a tds i guess ill get one...the last filter in my ro is turning brown in thye middle in green in one part and idk the other coler. i have been drinking jim so ill get back to you. i have had the ro for about 3 mo. but made prob more then 1000 g....
