    Looking at the reefmaster and reefmaster plus RO units from WaterBoy.

    Have a few questions:

    Whats the difference between the two?

    Whats the waste water produced for every 25L of RO made?

    Can i plumb this into my kitchen and drink the Waste?

    Waste = bottled water quality
    Pure RO = "too" pure, not so good for humans to drink.

    You can drink the waste water but you're going to have a lot of drinking water if you do a large water change. You can plumb your waste pipe on the RO unit into another membrane to reduce you water waste further. I have mine going into my pool. Ask Marco - The Waterboy what the difference is between the two as they are his units

    I think the difference between the reefmaster and reefmaster plus is the plus comes with DI unit and TDS meter where the normal reefmaster doesnt.

    Might be wrong.

    I've also been thinking about what to do with the waste water - plumbing it back in sounds like a good option. :thumbup:

    I recently got the Reefmaster Evolution Plus unit from The Waterboy.

    The differences explained to me by the Waterboy:

    Reefmaster is a 3 stage RO unit. (Sediment pre-filter, carbon pre-filter and reverse osmosis membrane)

    Reefmaster Evolution Plus is a 4 stage RO/DI unit with a flush valve. (Sediment pre-filter, carbon-prefilter, reverse osmosis membrane and a de-ionization post-filter).

    Depending on your tap water's quality you might not need the DI stage. The RO membrane removes between 90% and 98% of the TDS in the water and the DI will remove what is left over.

    I have also plumbed the waste line into my swimming pool, I'm constantly having to top it up due to evaporation anyway.

    andre is correct

    the waste water ratio is dependent on the t.d.s of the raw water comming into the unit

    the higher the t.d.s comming in....the more waste as the membrane must reject more to give you good quality water

    Marco, isn't the amount of waste water also dependant on the tap water pressure as well as the TDS in the water? Just asking
