hi, i have a 300 gpd system with the 3 fiter click catridges and the resin click cartridge, and if anyone also has the same type of filters and resin just wondering how long the resin cartridge normally lasts for? my tds has gone up to 8 on around 3 weeks whereas the previous one lasted a lot longer, cud i have had a poor faulty cartridge or is around a month the norm? i use virtually 350 litres a day, any info or help would be much appreciated, thanks.
