Hello, For 2 150 GPD membranes which auto flush restrictor size should I purchase from you? Been to your site and I am confused by the information on the site... 800 restrictor auto flush? https://www.bulkreefsupply.com/aquatec-auto-flush-flow-restrictor.html Unable to add an auto flush restrictor because I must use/update to capillary only? https://www.bulkreefsupply.com/reverse-osmosis-flow-restrictor.html I recently added your two DI resin canisters and completely overhauled the original filter that I also purchased from you. The new filter is: Booster pump, auto shutoff, 2 x 150 GPD membranes, 2 DI canisters, 1 single waste water line.
