    the only way you can do that is ask fellow reefers near you to donate some:) there no alternatives to making RO

    Well, maybe there is ONE other way. You can take your kettle and start boiling water for your life. You then need to catch the steam using a plate and let it drip into a drum. BUT, you gonna be boiling for weeks!!:lol:

    He said cheap! If he has a gas stove or electric stove that will cost more than the RO. ;)

    Since you are using NSW, are you wanting the RO for just top off water? Perhaps you could just purchase distilled water until you decide to purchase a RO unit. ;)

    I always thought there were contamination issues with storing R/O water?

    As in keeping them in sealed containers so that you dont get "outside" dirt particles mixing in the water again ....... Also by not keeping it sealed can start growing algae quickly as even the chlorine is taken out by the filters to bring your tds to 0

    if the plastic container has had chemicals or anything else with high tds reading it could have absorbet it. even containers made from recycled plastics can leak out stuff. only use virgin plastic containers :thumbup::1:

    Sorry Afsal .... just echoing what I read here on MASA .... If I get a chance will try and find the threads ....... I've personally never tested stored R/O water and as for my water its stored in a pressurized 12Ltr sealed container .... not by choice but thats how it came all together so didn't ask too many questions .... just went with the flow

    Just buffer the RO before you store it! RO will react with anything, even the atmosphere and plastics etc, if its buffered its much less reactive.

    Yeah and buying RO is fine for now but plan to buy the machine as soon as you can l afford, you'll be very glad you did - I saw one in a for sale forum the other day for like R350, needed filters of R150. Reason is that your always cleaning stuff around the tank, you'll use a lot more RO than just for topups, I always have around 50litres around just for weekly maintanance.

    Cheers

    i store my ro in a 90l jojo drum with screw lid, ro out of the machine is 0tds and out of the drum after a week is 2tds, so the water defn absorb something in the container.
    I have no algea probs and i drain the drum once a week for making sg and filling the topup chamber in my sump.
    you can buy water from oasis at 80cent/liter but the tds may vary and can be as high as 20

    lol......you guys are funny

    firstly plastic does leach into r.o.water......unless you have a polyprop container, the t.d.s can go up if stored for long........air can even contaminate the water!

    tiger ....your response was classic:lol:

    butcherman.....good on you:thumbup:

    ravi.....come see me........i have some old machines we can make bling bling for you.......you need to buy the spares , but you can pay us off.....
