We started our first pond build about a month ago and I've been following on the forum for ideas and help with the build. I finally thought I'd join as I am looking for some more specific advice for our situation.\n\nWe are doing this with the trial and error method. As of last weekend I readjusted our rocks for the waterfall and finished landscaping the edging to hide our liner. See photo for what it looked like prior to the latest adjustments. I'll have to repost with and updated photo soon.\n\nHere is some info about our pond now. It's about 800 gallons running on a tetrapond 1000 Gph pump. I currently do not have a filter setup. We kept hesitating as to what type of filter to install and if we should buy or diy. I'm not terribly handy but I will definitely give anything my best try! One of the reasons we were so hesitant about selecting the right type of filter is because we have pet ducks that will have access to the pond on occasion. They have a separate enclosure, but we let them out to free range when we get home in the evenings. I know from reading the threads that most ponders try to keep ducks out it seems like, but we want our ducks to enjoy the pond and we love seeing them swim around. So my question is what would be the best type of filter to either buy or make to run with our pump and keep it relatively clean.\n\nAdditional questions, would you recommend adding snails to help with the algae? We would like to add fish (hoping the ducks won't eat them!) any recommendations as to when we can start adding them? I just added a water lily, hornwort and some iris marginals a few days ago. I'm hoping to continue to adding to our greenery. We also have at least two gray tree frogs that have already found the pond. We kept hearing them in the evening and it wasn't until I went to make some adjustments to the waterfall rocks that I came across them! It was so exciting to know that some wildlife has already found our little pond.\n\n[ATTACH=full]70551[/ATTACH] \nSorry... Not sure why the photo keeps uploading upside down..
