First of all does anybody know the website where you can calculate how much resin you will use to your tds vs water usage..
also nest weekend i am moving to a house that has a water meter so want to go from my RO only to DI only i was thinking 11 litre but not sure what the disadvantages or advantages would be going smaller to a 7 litre or bigger to a 25 litre, my tds is really low between 40 and 60 and i only use about 200 litres a day 3 days a week, any preferences on what vessel or resin to get and where from???
cheers guys
