Now, "through the liner" made my hair stand on end. Do you mean you are going through the liner above the water line? I hope so. I am terrified of cutting through where it could spring a link sometime later. I don't know if you read my horror story about the leak I had. It went on some all last summer and continued this summer but then got terrible about 2 months ago. We finally found it and fixed it. I was relieved though that it wasn't in the pond itself or waterfall. It was between the bio filter and where the liner attached to it. There was caulk across a hole/dent about the size of a quarter. When the water was leaving the filter, it pushed the caulk down like a flap and when the pump was shut off and I was looking for the leak, the flap layed perfectly in place so of course I overlooked it several times. Finally I began pushing my finger on/in between corners, crevasses, cracks, looking for someplace I hadn't noticed before and when I pushed on that caulk

I FOUND IT. My DH mixed up some sloppy Quikcrete and I dug out a kitchen funnel. First he poured just the dry Quikcrete down the hole and then he finished up with the mix. IT did the trick.
You'll notice the frame guide in the laundry tub. That is plastic quarter round from Home Depot. It cuts easily and screws into place easily too. Being Queen of PVC, I used PVC to make the grate/frame that slides in the guide. The idea is to keep the filter media from being sucked into the pump. I did have a mesh basket in there before I started using the brushes. I like the brushes VERY MUCH. They catch the larger crud and boy do they clean easily. They just hang on another piece of PVC.
Typically, I use the brushes closest to the inflow opening, then a piece or course media, and then a piece of media with two types of finer filter.
Could you sit your tub on something inside of the pond? Trouble is, nobody likes to see it. You could spray paint it with black first. It would help. But still you'd want to maybe make a kind of dock or some way to cover it. Mine hides under a boardwalk. We left 2 sets of 2 boards loose or you could hinge it. Then I just pick them up to get at the tub. It also cuts down of the pump sound if it is noisy.
Bang around in the DIY sub forum. You may find some other interesting things to make your wife crazy.
