I will be going back down tonight to get the little bit of sand and water that is left. Scrape the coralline clean and buff out a few scratches. I guess the good news (if there is any) is I can hang the LED's now pretty easily now where I want them. I also think the closed loop is coming off for now too. I have the Tunze's and that Vortech on the way. Those are way less expensive to operate and will be less of a load on the generator. The vortech has he Battery back-up coming with it.
