Greetings to all the fishkeepers! I have attached several scans concerning the pond I have planned when the weather cools here in the Panhandle of Florida. I have an Intex above ground pool 12 feet round x 30 inches deep for my main liner. Its the one with the checker pattern inside, still, I think it might look good. I will shape the liner to fit the basic outline drawn on the plans. At the back of the 3ft waterfall will be my two 44 gallon biofilters being feed from a 44 gallon atmospheric balance tank, kinda like in a pool setup. Pictures say 1000 words, so tell me what you think. Also, can a algae eater live inside one of the biofilters...and should i have an aerorater in the pond if I have a 3ft waterfall splashing on rocks....and is 23 gallons per minute too much coming over the falls....greatly appreciate the tips...........
