RO/DI Maintenance??

[moose8721]

I bought this RO/DI system probably almost a year ago. I have no idea when or how often I'm supposed to change the filter media or do maintenance, etc. I probably only use about 10 gallons a week as my tank is only 38 gallons. Any advice is appreciated....

I have a reefkeeper from airwaterice, I change the DI cartrige every 6 months and do a full filter change once a year, I use about the same amount of water as you. I test it with a TDS meter that you can get from Walter, when the TDS goes above 5, I would also change the DI only. I have never changed the RO membrane, it's been about 3 years.

TDS meter is a great investment, cheap too

Thanks guys. I own a TDS meter. I just wanted to make sure I was doing everything I should be doing. Looking into it a little further, airwaterice website has a detailed instruction/installation manual that describes when you should change the various filters. Pretty sure I didn't get that when I bought it....just winged it til now. Thanks again!
