easerthegeezer said:stage 4 is deionization, removal and exchange of ions - you get a much lower TDS, 0 ideally. dont ask me any more than that as it is all brain melting science My RO TDS from hard cambridge tap water was 6 when i had it tested last.
Im sure someone could explain it in laymens terms but that someone aint me

thanks mate, yeah the 3 stage one I posted seller does a 4 for a tad more. So wasn't an issue, but would always go on recomendations so thanks, rather go for one recommended.billy boy said:Take a look at this 4 stage unit, I bought this one a few years ago and has served me very well and comes at a excellent price to.
I get my spare filters from this guy to with a first class service

easerthegeezer said:dont think the 3 stage goes so low, not sure what level though. I would suggest that if its for freshwater the likelihood of 3 stage at 30-50? TDS or 0-5 TDS from 4 stage making any difference is negligible unless there is a specific reason you need it that low. I think a lot of people, myself included, use it simply to make water softer so 3 stage would have done the job but i keep marine also. 4 stage does also give more leeway as TDS rises between filter changes if you keep sensitive creatures...high grade shrimp etc
