I put together a package of items needed for your customers project. I am using a Matala pre filter on a TW3700 AWG pump. This is because customer needs to make sure he does not pump junk into the 48" Acrylic Sheer Falls. I have a bulk head fitting so the tubing can go through the side of liner to get to falls. If he wants to go over the top of the liner instead of going through it, my quote will be a little less. I also have included a 64 oz of Fountec to keep water free of algae.
