    Question to Aqua-Safe ro/di owners

    Do you use the water at the last stage (carbon) or after the di (5th stage) ? Reason i ask is because the water tested at 25 tds after the last stage but only tested at 0/1 tds after "di".
    The instruction does mention because of carbon elevates the reading a little bit, and the true reading is after the di. So does it mean i should only use water after the "di", and not AFTER the carbon ?

    thanks,
    cn

    Cool

    ????? the DI is the 5th stage. the carbon is your 3rd stage I believe. yes use it after the last stage. for drinking water I used it just before the DI [RO membrane]

    Hi Johnny,

    It's the Aqua-Safe 100gpd unit i bought from AC and it does have the sixth stage (last stage). The instruction says the last stage is carbon i think.

    thanks.

    The last stage is "Carbon for taste".
    Some people have reported seeing some TDS when using the 6th stage, and remove it. It is not necessary.

    I'm using the 6th stage because I havn't had any TDS readings after the filter.

    OK, thanks tang_man. I'm not using the last stage then since it gives me some TDS.

    the tds readings your getting out of your last stage is just carbon dust... The whole unit should be flushed for about 2 hours before you get good readings.

    I use the water from 5th stage for aquarium. The water from 6th stage is for drinking.

    ahh okay you have the 6th stage which I just added. did you test right after hook up or when you first turn it on,if so you will get some readings but thats no big deal. you can run it after the 5th if you like.
