Im not a heavy resin user as I only get through 10 ltrs every 12-18 months since using a 4040.
But I've only ever used Tulsion mb-115 from Daqua (6 years) and I honestly have never had any problems whatsoever.
And I calibrate my TDS meter fairly regularly so I know I'm getting accurate PPM readings.

You wouldn't notice any difference using such small quantities.  I've had some right rubbish from all the top suppliers to.

Fair enough.
