reefriot Posted January 29, 2003 Share Posted January 29, 2003 got a question about RO/ or DI i sold my large ro/di awhile back and have been buying ro water from a damm machine for 35 cents a gal. well i was digging through crap out in the garage and came across a filter housing and a partially spent DI filter. so i hooked it up to my carbon filter on my sink faucet and check the water with my TDS meter. it showed a reading of 3ppm. now the water i was buying shows a reading of 5ppm. think i'm safe using just DI water for changes and make-up for the next 2-3 weeks until my new RO unit shows up? or are there other things in the water that the TDS meter doesn't pick up and that the ro membrane removes? thanks for any help aaron Link to comment
Twins Guy Posted January 29, 2003 Share Posted January 29, 2003 hey reefriot- DI is great water-its just spendy to produce-that's why most people run DI only after RO-extends the life of your cartridge. TDS just stands fer total dissolved solutes-so you're not missing anything cuz there really isn't anything there. i'd trust your DI way more than that crap store water (but i'm a hypocrit who buys my water at supervalu). you never know when that store cartridge is gonna start to deteriorate. obviously though you have the TDS and can test easily. either way you should be just fine. HTH! tg Link to comment
