dang, that's sad. I sent info and pic just before you messaged me. So, I don't know if you saw what I said. I added a picture, too, since people usually request one when solving problems.
I purchased a “reactor” off Amazon and some chaeto from my LFS. I put the return pump into the back of the tank and plumped some vinyl tubing into a small black tote from Lowe’s. I then got some grow lights and light strips off Amazon and put them in the black tub. I’ll attach some photos for you as well. It’s crude and ugly, but it’s worked just fine for 10 months now.
I ended up removing the LED strips because it was too bright.
