Not to dig up an old thread but I just got back in town. I was gone for 8 days. I cleaned the skimmer before I left, that was all. My mom & dad came over a feed the fish, this is all. The tanks are both running perfect and I owe it to automation. I could do not want to imagine having to do everything myself. I work several hours on it everday as it is. Anyway, I just got home, cleaned the glass, and now I want to go enjoy it.
