Using some type of meter is not a bad idea to insure the water you got out of your RO unit last week/month/year is the same quality of water you are getting out of it this week/month/year. RO units do fail, and I never mentioned RO units or RO water in my reply as I use NON-RO water for many plants/setups and have in the past used NON-RO water for CPs. Something a TDS meter is very useful for when doing.
That is the problem, a lot of other applications where they shouldn't be and the results are misinterpreted. It's not just opinion, that is a fact.
Dunno what to tell you, your meaning of fact is far from mine and the a lot of third party sources, the meaning of the word for instance.
Telling me where I should and should not use a give tool is silly, if I understand the tool, how it functions and what the reading mean, if you want to be helpful in this thread please add to why using a TDS meter is a bad idea or a better way to use the meter. Not just a , explain.
Look into how TDS meters are being using in hydroponics and aquaculture.
The intention of a TDS meter is to well...measure Total Dissolved Solids in a solution...NOT monitor RO membranes. They are being used to monitor membranes because they work really well for that purpose. This is a fact.
It seems that this is a touchy subject, and I've seen it discussed before.
The majority of what I'm hearing is that it's not important, with one or two people saying they clean them occasionally (once / twice a year)
If there's no additional input that isn't an argument, I think the thread has served it's purpose. Thank you to everyone that answered. It gave me some things to think about.
I just checked a tray and got a TDS reading of 243. Please tell me what it means.
