Do I need to rinse it before uss to achieve 0 TDS? Sent from my C6833 using Tapatalk No need to rinse resin. The flow rate will have to be very low to achieve 0 TDS. I adjust mine to a trickle and collect the water in a container overnight. I collect about 6 litre overnight and TDS 0. One small cartridge of resin will give me about 100 litres of 0 TDS water. Of course if you use larger volume of resin you can increase the flow rate. Any pic of you DI unit? May be able to offer better suggestion after seeing it.

SRC Member pcw Posted December 15, 2016 SRC Member Share Posted December 15, 2016 Using resin only will not remove undissolved particulate matter (rust particles etc.) That is the job of the 5 micron filter. Quote Link to comment Share on other sites More sharing options...
SRC Member yukok.lim08 Posted December 15, 2016 SRC Member Share Posted December 15, 2016 Mine is zero TDS just using 2 stage of resin, so it can be done .Btw, if your TDS of tap water is above 100( not sure) , is really hard to get zero tds with resin only. My tap water is around 70 tds before filter.Sent from Singapore Reef Club mobile app Quote Link to comment Share on other sites More sharing options...
oceanics Posted December 15, 2016 Share Posted December 15, 2016 Sad leh TDS @ 140 after using resins. Tap water @ 70+ but dont know how come after filter using resins it shoot up... 1 Quote Link to comment Share on other sites More sharing options...
oceanics Posted December 15, 2016 Share Posted December 15, 2016 Oh btw am using a simple setup, mineral bottle filled with 300gm resins and 1 drop per sec. Do u think it works? Am trying out first by using just resins before getting a proper set. Bro reefbuilder can share hows ur setup? Thanks! Quote Link to comment Share on other sites More sharing options...
SRC Member Ashtrax Posted December 15, 2016 SRC Member Share Posted December 15, 2016 Yolo... Actually i want to check what are your tips on WC, in order to get a salinity that you wanted easily? Quote Link to comment Share on other sites More sharing options...
oceanics Posted December 15, 2016 Share Posted December 15, 2016 You using NSW or salt mixed? Quote Link to comment Share on other sites More sharing options...
SRC Member reefbuilder Posted December 15, 2016 SRC Member Share Posted December 15, 2016 I have a cabon cartridge followed by resin cartridge. As suggested by pcw a 5 mocron filter will be good. As for Yukok and who do not use carbon yes can also achieve 0 TDS. Research have indicated that chlorine and chloramine will cause the resin's effectiveness to be depleted faster. The carbon is meant to be a prefilter to remove them so that the resin will give you more 'mileage'. But then again the community is divided on this and the debate goes on. I have no answer why the TDS went up after going throught the resin. Maybe others can offer some insight. Quote Link to comment Share on other sites More sharing options...
SRC Member reefbuilder Posted December 15, 2016 SRC Member Share Posted December 15, 2016 BTW I am enclosing a picture of the unit I am using. Bought from madpetz. As mentioned earlier one cartidge of resin is giving me an average of 100 litres of 0 TDS water. I will change the carbon once the volume of 0 TDS drops to about 50 litres to a cartridge. The volume of 0 TDS obtained will of course be affected by the TDS of the tap water. My tap water has a reading in the range of 70 - 90 TDS.

SRC Member Ashtrax Posted December 15, 2016 SRC Member Share Posted December 15, 2016 So After reading getting a carbon and di resin is the best. Actually what are the trick do you are use to mix salt water faster? Quote Link to comment Share on other sites More sharing options...
