Jay Posted September 29, 2010 Share Posted September 29, 2010 Like the title says.....whats your waters ppm after the ro filter but before the DI resins have filtered it? I want to know because mine is 16 ppm and was wondering if my membrane is bad? By the way.....my aquarium is still for sale and has been reduced another hundred twentyfive bucks to $525. whoever gets this also gets the rest of my powerheads and misc crap thats left in a bucket....(like that's really incentive right...but the cash reduction is) Kinda a duel purpose thread Jay Quote Link to comment Share on other sites More sharing options...
Harold B Posted September 29, 2010 Share Posted September 29, 2010 I just got my TDS meter after having my RO/DI for 3 or 4 months now and was suprised that my readings before the DI are 0 and after of course is also 0 but with a 0 reading before my DI my DI resin is still turning from blue to lite brown Hmmmmm go figure? Yes I would replace filters for sure! Quote Link to comment Share on other sites More sharing options...

Chief Posted September 30, 2010 Share Posted September 30, 2010 About 23 out of the tap, 0 after the RO. No need for DI. Jay Quote Link to comment Share on other sites More sharing options...
reefnjunkie Posted September 30, 2010 Share Posted September 30, 2010 I cant test after the RO, or at least dont have my meter in line that way, as it looks like most dont either???. Mine is around 10-18 (depending on rain etc-Bull Run water) out of the tap and of course 0ppm after it goes through the RO/DI Quote Link to comment Share on other sites More sharing options...
ocboat Posted September 30, 2010 Share Posted September 30, 2010 Mine is 210 out of the tap, 20 after RO outside of Oregon City in Clackamas River Water District. Used to be much lower when I lived in town in Oregon City in different water district. Quote Link to comment Share on other sites More sharing options...
Barelycuda Posted October 1, 2010 Share Posted October 1, 2010 I fall in line with the other Vancouverites. 160 out of the tap and around 4ish after the RO. After a couple weeks it will creep to around 7ish and I do a 15 minute flush of the membrane and it drops right back down to 4. From what Air Water & Ice told me their membranes remove around 96-98 percent of the tds which seems to work for me. Quote Link to comment Share on other sites More sharing options...
grassi Posted October 1, 2010 Share Posted October 1, 2010 What do you guys use for testing? Quote Link to comment Share on other sites More sharing options...
Barelycuda Posted October 1, 2010 Share Posted October 1, 2010 I bought the dual inline TDS meter from Air Water & Ice. Works great and now I just push the button to get both readings. Super easy and well worth the money. Quote Link to comment Share on other sites More sharing options...

blown65 Posted October 12, 2010 Share Posted October 12, 2010 My drinking water R/O is about 5-6 post with about 300-400 in. (on a well, it will vary) Membrane is 8 yrs old. Fish tank setup is same in, about 5-10 out then 0 out of the DI. Pretty new membrane right now. Haven't checked post RO for a while. Quote Link to comment Share on other sites More sharing options...
grassi Posted October 13, 2010 Share Posted October 13, 2010 For all of you, me included, with digital dual tds meters, I was at Danik's place a few days ago and he showed me how the digital dual tds meter was saying 0 while another more accurate meter was showing a significant amount of tds in the same reservoir Quote Link to comment Share on other sites More sharing options...
reeferscooter Posted October 14, 2010 Share Posted October 14, 2010 Mine reads about 7 from the RO and 0 after the DI. I live in Redland about 5 miles out of Oregon City. I use a digital meter i got from my lab. Quote Link to comment Share on other sites More sharing options...

ocboat Posted October 14, 2010 Share Posted October 14, 2010 I also live in the Redland area and use the dual digital meter. Maybe I could meet reeferscooter to compare TDS reading. Quote Link to comment Share on other sites More sharing options...
