  1. Default RO vs RO/DI Which one should I use?


    0 Not allowed!
    I have been racking my brain today trying to select a unit. I would like a 75 gpd unit at least. It again is one of those items that have so many options and I am unsure of getting the correct one. I don't want more than I need but don't want to fall short either. Any suggestions?

    If you're going to buy a unit, go ro/di. Might as well get your TDS to zero and save yourself questions later on. An RO only unit does not get you zero TDS - tho if all other factors are perfect in your tank you can certainly get away with it.

    But I'd go (and do have) with full RO/DI.

    I would suggest a 5 stage unit with three stages of catalytic activated carbon, followed by your membrane, and finally a DI cartridge. That is the basic design that I had for mine

    That will get you a 0 TDS output that sheamuria recommended.
    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

    Any particular brands or models or are they all pretty much the same? I was looking at this one from bulk reef supply - http://www.bulkreefsupply.com/brs-5-...em-150gpd.html

    Would like to spend a little less but since I am going to give the new old skimmer a go I at least have a little time to upgrade that if needed. I don't relish the thought of lugging some 150 gallons of RODI from the grocery store lol.

    If you are pretty handy completing DIY projects, you can get a really cheap 3 stage unit, add additional cartridge holders, and replace the carbon and membrane wit better quality ones once the current ones need replacing. That is what I did and I saved some cash
