+mcallahan Posted July 30, 2009 Share Posted July 30, 2009 I tested the water in my RO/DI barrel yesterday and it came out @ 4 TDS. I then tested the water straight out of my RO/DI unit and it read 0 multiple times. So I concluded there might be some residue in my barrel. That being said, I filled my 5 gallon jugs with water (same ones I use to top off my tank and mix salt) and overnight, the TDS in there rose to 14. So, is there good TDS and bad TDS? I figure the water in my mixing jugs has a TDS of 14 due to residue from the salt mix and buffer solutions, so would you say that TDS is bad, or just a normal part of using jugs to mix water?

+dapettit Posted July 30, 2009 Share Posted July 30, 2009 Did you fill your jugs using the barrel water or straight from the unit? Quote Link to comment Share on other sites More sharing options...

+dapettit Posted July 30, 2009 Share Posted July 30, 2009 Most likely the residue in the mixing jugs. I hope someone else will confirm. Quote Link to comment Share on other sites More sharing options...
+mcallahan Posted July 30, 2009 Author Share Posted July 30, 2009 Most likely the residue in the mixing jugs. I hope someone else will confirm. I figured so, and I wondered if its a bad thing to have dissolving into one's water. Quote Link to comment Share on other sites More sharing options...

+dapettit Posted July 31, 2009 Share Posted July 31, 2009 Do you rinse out the jugs after use? Might use DI to rinse them. I'm not sure if this could be part of your diatom problem. hmmmmm Quote Link to comment Share on other sites More sharing options...
JimD Posted July 31, 2009 Share Posted July 31, 2009 Put some water in a new plastic sandwich baggie, test your tds from there and compare notes. Quote Link to comment Share on other sites More sharing options...
Robb in Austin Posted July 31, 2009 Share Posted July 31, 2009 I can provide a sterile cup for ultra control testing. Quote Link to comment Share on other sites More sharing options...
texmexbigspring Posted July 31, 2009 Share Posted July 31, 2009 Personally I belive it to be normal. Mine does the same thing. 0 straight out but in the barrel its at 1 or 2 just my two cents Quote Link to comment Share on other sites More sharing options...
barderer Posted July 31, 2009 Share Posted July 31, 2009 Unless your clean, dry and cover your mixing container when its not in use, you will get some TDS. There are good and bad dissolved solids. Left over salt and a little dust from the air are fine. I wouldn't worry about it. Quote Link to comment Share on other sites More sharing options...

I was figuring that, esp. since I "dope" my top off water with Ca, Mg, Alk solution, Iodine, etc. AT some point, SOMETHING is going to get in the water.

neal90 Posted July 31, 2009 Share Posted July 31, 2009 I have been told that water with 0 tds is so pure that I will attract tds like a magnet. Even the little that is in the moisture in the air. I just gave up trying to keep 0 tds in my top of water and just deal with it Quote Link to comment Share on other sites More sharing options...
JimD Posted July 31, 2009 Share Posted July 31, 2009 I never let my tds get above 3, always have filters and DI ready to go, its not expensive, maybe thats why I dont have any algae issues?? Quote Link to comment Share on other sites More sharing options...
