Need some help regarding an RODI system. In preparation for filtering 200+ gallons for my new waterbox 230.6, I recently upgraded my RODI with 2 150gpd RO filters running in parallel, to essentially double it to 300gpd. The first day after I set this up I filtered 5gal of water in about 45minutes. It's been 2 weeks since then, and I've filtered maybe 8-10 5gal containers worth of water for ATO and water changes in my current setup. Today I went to filter some water, and it's taken an hour to fill half my 5gal container. My water pressure gauge on the input line is showing 60psi which is normal for it. I'm confused how this has slowed down so drastically in such a short period of time?? Does anyone have an idea as to what might be going on here?
