After reading good things about Daqua on here I thought I'd get my new membranes from them as they were a bit cheaper than Pure Freedom where I normally get them.
Unfortunately I wish I had stayed with Pure Freedom, their membranes get my tds down to about 7 or 8 ppm from a tap tds of around 300 ppm, but these new Daqua ones are only getting down to about 55 ppm.
Anyone else had trouble with these membranes
