    Hi All

    Not sure if this is the correct place to post this but i need some help.

    Anyone know the difference between the normal Ro units example 5 stage unit and a 4 stage marine RO unit? Can the normal RO unit be used for marine tanks? Also if i go with the marine RO unit can i drink the water that is produced as well?

    Details are listed below for both units.

    5 stage normal unit.
    Stage 1: 5 microns sediment pre-filter
    Stage 2: Activated Carbon pre-filter
    Stage 3: Carbon block pre-filter
    Stage 4: 50 GPD TFC Reverse Osmosis Membrane
    Stage 5: Inline GAC filter


    4 stage marine:
    Stage 1: 5 microns sediment pre-filter
    Stage 2: Carbon block pre-filter
    Stage 3: 50 GPD Reverse Osmosis Membrane
    Stage 4: Inline Resin Filter

    Dont drink marine RO, doesnt contain any minerals. Houshold RO replenishes your water with needed mineral, houshold RO not for marines.

    @Shaun88 .Where in the above setup does the household ro system replenish minerals?. The RO membrane strips the minerals. The GAC inline filter does not add minerals back.
    drinking RO water is not bad for you. The lack of minerals in the RO is more than made up in other food intake. If you are concerned about lack of minerals, drink the waste water ! - after all that has already been prefilterered and gone through carbon filtration before going to waste.

    It tastes like something is missing from it. lol. Just out of curiosity, is it safe to consume the waste water?

    yes, i bottle the waste and use in my water machine...
    waste water is still better than most "mineral" waters out there
    which are made with RO machines IIRC
