Hi scratcher get yaself a bigger Di bottle. I've got a 450 gpd with booster pump and a 25L Di bottle takes 3/4 of a big bag of resin which has lasted so far around 9 months and I'm on 002.

I have a 300 gpd ro and small 10" canister for resin that will produce approx 1,000 litres of 0 ppm pure water before the resin starts to creap up to about 1-2. My tap water tds is between 260 -300 but everytime I want to strat producing pure I disconect the di canister and backflush the ro for a few mins to stop tds creap killing my resin
