For sale are a used pond vacuum, aeration kit, and uv clarifier. The vacuum and aerator work fine. The uv clarifier does not. It has a good bulb but also has an internal wiring issue. I don't know if it can be fixed or not.
PondAir2 aerator with one air stone: https://www.thepondguy.com/product/crystalclear-pondair-aeration-kits/ ($59.99 new)
New air stones are very cheap: https://www.thepondguy.com/product/crystalclear-airstones/ ($4.99 per pair)
Oase Pondo Vac Classic: https://www.thepondguy.com/product/oase-pondovac-classic/ ($327 new)
I have the two hoses and several plastic extenders, but am missing most of remaining accessories.
UltraUV Pond Clarifier (18W)
https://www.thepondguy.com/product/the-pond-guy-ultrauv-pond-clarifier/ (18W - $179.99 new) Again, this doesn't work. I'll throw it in for free if you want to try and fix it. Otherwise it's headed to the landfill.
Please respond via CL email with questions or interest. Thanks!
