As for s cheaper efficient skimmer, you might want to look into a bubble magus. Maybe a curve 5 or 7. They are good, cheap, efficient skimmers. I have had 2 curve 7's, and they worked great.

As for the fuge, I see a couple options without having to modify too much:

You could add a glass or acrylic baffle on one side of the sump and connect it with your return pump to make the fuge. Simple and affordable. Just a piece of glass or acrylic and some silicone.

You could purchase a hang on fuge like a CPR. Or even modify an aquaclear 100 into a hang on fuge. If you look up "aquaclear fuge mod" you'll see a bunch. I have used many of these and they work fantastic.

Or you could stick with your current design, and use a 2.5 or 5 gallon smaller tank and place it within the sump. Then feed it with a pump or from your overflow. It would simply overflow back into the sump. Might look a little better than a bucket, and hold more volume due to the square shape.

Tagging along to see your progress!
