    Advise on rodi water

    in General Reefkeeping_

    Posted

    Hi fellow reefers,
     
    I’m using a second hand madpetz 5 stage RO-DI system. Pressure gauge is not working.
     
    Tap water (75ppm) runs through stage 1 (rust & sediment filter) followed by stage 2 (granular activated carbon filter) then stage 3 (carbon block filter). Water ppm after 3 stage is (74ppm). After stage 4 (RO membrane), water (9ppm). Lastly after stage 5 (Resin) water (2ppm).
     
    Have bought this from a fellow Reefer, didn’t change any filters so far as I was told that by changing the resin it would be able to maintain 0 ppm water.
     
    Would require some advise if it is normal for water ppm after going through 3 stage filter to be only 1 ppm difference from tap water.
     
    Any idea if the pressure gauge can be replaced?

    Lastly, do u guys install a pump booster to rodi system? As I notice the water from the tap is quite strong, but as it comes out from the resin, the flow is really very slow compared to the tap. Staying in HDB .

    Newbie Qns on biological filter maintenance!

    Hi fellow reefers, I’m new to this hobby! Would require some advise.

     

    I’m currently running a new canister filter for my tank for 2 weeks.

     

    Just wondering when I’m doing maintenance for the canister filter’s biological media, am I able to use rodi water to rinse the media? Will it kill or affect the beneficial bacteria in it? Or do I have to make a salt mix to wash the biological media?
