rgrcrain Posted June 4, 2012 Share Posted June 4, 2012 I finally got a TDS meter and my water was at 9 or 10, I've changed all the filters so its back to 0. My question is what is really considered bad with TDS? Also, I had a chlorimine carbon block and now I don't, do I really need it in Vancouver?

cellowithgills Posted June 4, 2012 Share Posted June 4, 2012 Don't know about Vancouver water but I think anything below 5 is pretty good without DI resins. Some people are really picky and want absolute 0 but I didn't notice any big differences when mine got up to about 12-15. Quote Link to comment Share on other sites More sharing options...
kriz2fer Posted June 4, 2012 Share Posted June 4, 2012 I would shoot for zero. If there is a tds reading of 8, do you really know what that 8 is? could be copper, could be cholrine. We dont know, the tds only tells you that there is somthing in the water. Quote Link to comment Share on other sites More sharing options...
reef165 Posted June 5, 2012 Share Posted June 5, 2012 And the higher the TDS the faster the alge grows. Quote Link to comment Share on other sites More sharing options...
Burningbaal Posted June 5, 2012 Share Posted June 5, 2012 I'm actually planning to stop my RO at some point here...I know, sue me. I plan on having 3-4 filters that are not the stock ones (probably have a 1uM sediment, one micron carbon, a 0.5uM or smaller carbon and a alumina one (for fluoride)), I'll test the conductivity (which is what the TDS meter is actually reading), and if I'm happy, let it be. I may be a little less than thrilled, so I may put a DI resin after the 4 filters, but I think it won't be necessary. I'll get about 4x the water production per hour without the RO and 4x the life of the filters (gallons per replacement) and am expecting near-0 tds. the sediment will remove particulates, the carbon will remove any organics and chlorine (corvallis doesn't use chloramine) and roughly the only thing left is fluoride, hence the alumina filter. if you're in portland, they don't fluoridate the water, so no need. if you're on a well, you'll probably need to start with larger sediment filters and might struggle with trace metals (heavy water). just my $0.02 Quote Link to comment Share on other sites More sharing options...
