Sorry, totally forgot about this thread. Here's a pic of the filter:
A couple notes on what I would do differently. I would use bigger holes, as it's hard to get much flow through those tiny little holes. I have a little, but probably 100% of the water every... 8 hours? Not the best, but good enough for shrimps. I took the shiners out, and put them in a different tank. It's now a shrimp tank... and the bloody shrimp have found a way into the filter! Ohwell... as long as they're alive and happy, who am I to make their life choices for them?
So, bigger holes, OR cut a half inch wide slot down the center of the PVC , about 2 inches down from the top.
Also, I would add a top to the filter, so when the water is full, it doesn't spill over the sides.
And the hose idea isn't working out so well. Do yourself a favor if you use something like what I've set up, and run your air hose through a piece of 1/2 inch PVC. Put two 90 degree fittings attached together, to make a 180 degree fitting, and have the one piece of PVC go all the way to about 1/2 an inch from the bottom of the tank. Now the air hose only has to be about 5 or 6 inches into the PVC. But fill a good couple of inches of that PVC up with GE 100% silicone, so the air hose can't come out.
Then you will need to weigh the 1/2 inch PVC down. I would personally use a smooth-to-threaded coupling on the 180 degree coupling (on the side that is out of the aquarium) and attach a galvanized pipe to said threaded coupling. This will keep the 1/2 inch PVC pipe from trying to float, and rattle in the vase.
As you can see, I just put the heater into the large piece of PVC. It's out of sight, and out of mind. Perfect.
Again, sorry I took so long to post about the filter. Once I get the chance, I'm going to fix mine... trouble is, now that I have plants, rocks, shrimp, etc. in there, it's going to be a huge chore trying to get the bio material out.
