Just thought I'd ask question on here about recent TDS findings. Both myself and a friend have recently purchased new RO Units (been running a month actually) I have also fitted a new 3 probe online meter to my own unit and both my friend and i purchased new TDS handheld testers.
We both live approx 1 mile apart and our incoming water is approx 360 TDS.
My unit (rated 200gpd) has 2 blue membranes (boosted by booster pump at 60psi) and the usual 3 pre filters plus 2 DI Pods (Resin changed 1 month ago). Pre DI my probe reading is approx 12 TDS and after DI it is 0.
My Friend just runs a 50 gpd low pressure membrane (with no booster pump/inline TDS meter) and no di unit yet. Yesterday we both tested our water with our 2 handheld testers with his reading 22 and mine reading 20 on his units water sample. When we tested my own we both got a reading of 5. I am therefore pretty sure we both have pretty accurate measures.
My question is really about the achievability in this hobby of regular 0 TDS? I would also find it quite alarming to contemplate just what local LFS are selling and was wondering what you guys think? Please feel free to comment on how to improve if possible? Since as Mr Saxilby says "we don't look after fish or coral we look after water" This is regarded as an essential part of the hobby.
