Vance- Yes I do have the water circulating through the water bridge, but with a rather passive pump. I hooked a 1/2 inch hose to the ventura of a power head and have the hose going between the tanks. Thus the ventura pulls water from one tank to the other and it returns via the water bridge. I have used this passive system, rather than a direct pump, since I don't want any overflows if the water bridge would somehow get blocked by plant leaves or lose its siphon. The venturi moves about 15 gallons per hour. I have tested blocking the water bridge and it cannot lift enough water to overflow the tank.
For the window boxes, I have a small mini-jet 404 pump in each box to circulate the water and also one pumping water up to the large tank system through an airline hose. Since it has to lift this water, it can only pump it at a drip rate which I have measured at one gallon per hour. Then there is an overflow on the large tank that goes back to the window boxes. So far, I like the airline tubing choice. The flow is so slow that when I do water changes and it is pumping to the main tank, but not overflowing back, it is no problem since during the 15 minutes I am changing water, the window boxes only drop by a quart.
The new over head lighting with the skylights has created a problem that I did not anticipate. I am getting algae growth in the water bridge since there is light on it that was not there before. I may have to make it a covered bridge.
There have been some changes. First, the acrylic window boxes are gone. In January I heard a loud pop and one of the window boxes had sprung a slow leak. It was a very cold day and the shrinking and expanding due to the temperature changes by the window were too much for the acrylic box. I was lucky that I was in the room at the time. Thus, I used Wolfram's idea of putting a plant shelf above the aquarium at the back. I used a 6 inch diameter 8 foot long PVC pipe.
Here it is right after installation. Water from the tank is pumped into the left side and overflows back to the tank on the right side.
Here is the 75 gallon tank that is attached via the water bridge. The java moss has really taken off.
Now for some fish pictures. First Killifish.
Panda Garra. These have such personality that they are really wonderful.
Horsefaced loaches. I really like these. They are out a lot, but I often see them disappear in a cloud of sand.

Jim P.- There's one of your guys right in the middle bottom. They are both doing really well and are quite active.
The plants that I have growing in the PVC pipe are pothos house plants, cherry tomatoes, some lilies, and some kind of fern. The lilies aren't doing much, but the others are growing quickly. Earlier I had some water hyacinth, but it all died. In my experiments, I could keep it alive and grow it, but only if I put extra T5 lights right above it.
I am very satisfied with the sky lights since I only need to turn on the T5s for a couple of hours in the evening. I also like the fact that with the lighting being natural, the tank always looks a little different depending on what kind of day it is outside.

That kubotai on the "assorted Loaches" photo looks like she´s about to explode. She´s too fat!

Looking good, I seriously envy your natural sunlight tubes. So great.
Beautiful healthy fish, too.
Sorry to hear the windowsill boxes were discarded. The tube on top of the tank does the same job, I'm sure.
I was inspired by your design on the original boxes and got around to making one myself. I ended up making it of glass and big enough to fit a separate growing box in.
Thanks for the inspiration!
hx- I like your window box. With it made out of glass and not set all the way into the window should make it work well. Good choices. Your plants look like they are growing very well. My leaves were kind of yellow at first and I read that this might be caused by a lack of iron. I started adding a small amount of iron to the tank and it really made a difference with the leaves growing in with a nice dark green color.
I just didn't have the guts to try and grow herbs in plain water with no substrate.
Yours were (and are?) in just water, right? Or do you have some sort of substrate in that tube?
