Disappointed with resin consumption

[Dragbag]

So I thought I better test my Tds I only use a about 100 L a day bought a brand-new filled11 D I from daqua back at the end of august andThe tds going into the di was 10 at the end of August and was 9 this morning so all good on the ro front. But the tds after the di is fluctuating between zero and 1 when I take 3 4 5 samples. So I have ordered some more resin from daqua to change maybe tomorrow.... I thought it would last longer than this, any thoughts Calling Spruce

Try taking a measurement from a larger sample. My tds shows 0-1 when I measure from a cup, but always 0 when measuring from the barrel. Perhaps my measuring cup were dirty...

yea just ro"ed and di 1 barrel ( 20 l) to see.. came out a 1, but just filled up some barrels from a 200l storage tank and there zero.i have got some new resin ( but never done a resin change before /emoticons/sad.png beeing a noob ) i bought a resin and funnel as well. should i change it now or keep cleaning with the tds at 1? also any tips on doing a first resin change would be helpful, iv seen gardiners video on how to change, but are the di vesels hard to unscrew

They're easy to unscrew, takes 15 mins to do a 11l vessel, did mine last night at 3ppm
