I already have an old (5yr) 1600gph filter and comparable 1600gph submersible pump in my 2400 gallon enlarged koi pond. I clean both of them. I replaced inside filters and the UV light in the filter and they are both working really well in my newly enlarged koi pond. I'd like to put in another waterfall therefore I bought a new 2100 GPH submersible pump but since I already have placed the 1.5 inch black corrugated hose in the pond I laid my rock all around it to eventually attach to a filter. Now I can't find a filter that has the adapter opening to a 1.5 inch size. I've returned two outside filter units because I could not find a 1 1/2" iadapter to fit the 1 1/4" openings on these filter units. Does anyone know of a 2100gph outside filter unit that would have a 1 1/2" opening? I cannot undo the stack flagstone and rocks because it's hard to get to some of these rocks. This is a shot of part of my pond.
