quick update, cleaned rez out yesterday morning and grabbed a bottle of "Green Fuse" referred by the dro shop as a worthy product so I have added a bit to the mix. Cleaned out a couple drain tubes that had some roots growing in them which I then had to trim the bottoms of a few, it wasnt much but enough to possibly clog it eventually. Will be changing the drain to three quarter inch, line and nipples to avoid any clogging. Was lucky to see the drain slowing down in the rez before clogging could accure, sheeeew. gooday to everyone
