Had a meeting earlier with a potential customer about the pond that was at the house she recently purchased. She contacted someone last fall to redo the pond and gave him all of the information on the system. He hasn't called or responded to her calls. It's a fairly small pond with an upper pond measuring 20'x6'x'12-15" deep, more like a lazy stream. Then falls down a cascading waterfall to a lower pond that is 12' x 8' and 18" at the deepest. She has 8-10 Koi in this pond, i know it's not deep enough for them. The total pond system is 2,500-3,000 gallons. She would like to redo the pond system without rebuilding the entire pond. The original contractor installed a 3/4 HP Sta-rite pump, Aquadyne 2.2B bead filter, a small skimmer, less than a foot in diameter that is in the pond and connected out of the bottom. And an additional 6 amp submersible pump in the upper pond that feeds the biofalls. I'm unfamiliar with a set-up like this. I know it's overkill for this pond. Would it be better to install a larger skimmer with a submersible, like an Aquascape system? Or make use of the large bead filtration and upsize the pump to 1.5hp? She'd like to reduce the maintenance and eliminate the heater. One step is to remove a tree that overhangs the pond and produces flowers, berries and leaf debris. Looking for a little input as to what is the best course of action for this customer. I'll try and provide you with any information that i can get. Thank you.
