Problem is.. the R of the RDWC isn't doing it's job. I have to ph once a day. Usually some stay in the range and one or two go to 4!!!! Ect.. sucks man. I'm going to clean then out and see what can be done. But for now it looks like there will be no recirculation. MASSIVE pain in the ass I can assure you.. but it's more satisfying as I genuinely put a shit tone of work in. Next time I set up it will be in a nice big room, panda plastics everywhere, tables, work bench, nute shelves ect. But for now I've just given up on recirculation.
