TDS meter question

[imdaring]

as you all know I have had a huge brown algae problem in my tank.. I bought a RO/DI system a year ago last July but never had a TDS meter.. I just got one to hook up to my RO/DI system.. what should it read for the PPM?? it has a in reading and a out reading.. I don't have it hooked up yet but I placed the out line in the bucket of RO water and I had a reading of 010ppm does that sound right or is this the problem with my water???

i think that 010 or 10 parts per million is on the upper limit of what you want as output, but, remember that if your just starting to use the filter system, that your probably gonna wanna dump the first few gallons that it makes, just to let it get flushed out.. but then after that, i would think that anything under 10 would be good.

My curriosity is whats the in measure? if its like 300+ then i'd say the filter is working, smile and be happy...

True. Test your incoming water and see what it is reading. 300-400ppm ?
Then a reading of 10 is great!

if 10ppm is good then what is the range for when I need to change the filters???

10 is okay. Not bad enough to cause any problems.

 

[imdaring]

what is considered bad so I know when to change the filters and stuff

my rodi runs at 0 so i think if mine got to 10 i would change the filters maybe your tds needs calibrated. but i would start thinking a about changing them

my tds is hooked up to my last stage (the di stage) and it reads 2 or 3 in and 0 out.

Wow Houston water must be great if it's reading 2 or 3 in! My tap water reads 400 or so in. I change my filters when it gets up to 10% of that, around 40.

I read that as hes testing the water into his DI stage and out of it.

Your right Biff! Our water here in Tucson is crap. At my house it reads 465 coming out of the facet. I recently got new filters and replaced them and still got a high reading that I thought was too much. So I got a new unit from Bulk Reef Supply and now I'm finally down to zero again. I love my new unit! :)
