Actually that would have helped out a ton if I would have epoxied sand all over the piping in terms of brown algae growing on there... And it would help with the look but I think I'm going to try some driftwood and see what happens I think I found my piece in my yard.I love driftwood, will still come to a tire-screeching stop if I spot an interesting piece while driving alongside a body of water. Always keep an axe, saw, pair of rubber boots, rope and other assorted collecting gear in the truck...just in case...
But pipe has its advantages as well. A couple lengths of pipe displace almost no water and take up very little space. I like ABS pipe as well, I find it much less ugly than the white PVC many people choose, but it's still not exactly pretty. You can sand down the pipe to remove any lettering and to tone down the shiny black surface; also use a file and then sandpaper to deburr the sharp edges where it's cut. You can glue two, three or more pieces of pipe together with epoxy or solvent cement, at any angle, and create a stable structure that won't roll and is difficult for fish to move around.
It's also easy to slather the surface with clear 2-part epoxy and then roll it in sand or gravel, or sprinkle the stuff on top. When the epoxy hardens you have a much more natural look. You can add pieces of plastic plant, shells, or other decor, and fish-safe paint can help out as well.
Dang...I sound like a bot...
I don't know where it's from it's been in my yard for 6 years. Too tall but I'm trying to think of where I can cut through my polycarbonate lid and then have the pothos grow up the top of the wood.
