Yes, i believe the best way is to make a waterfall, but still don't know how am i going to do it.cichlidgirl;1597791; said:I have the same problem in my outdoor pond in the summer months with turtles, they go in then cant get out.The pond freeze solid in winter. Also birds fall in and cant climb out. I put a little 2x4 in a spot that is not seen easily and they find their way out. No more deaths. Works good.
Your green house is wonderful. You should be very proud. Im sure the fish feel natural in them. It looks wonderful. For your wind power and oxygen, what about if you use a windmill to run a water pump like farms do, pump it up into a holding tank where it flows into cascading series of waterfalls, just think how wonderful the moving water will sound as it flows over the rocks. i have 6 large tanks and i dont use a single air stone. I let my water level be a couple inches low and the water from the filter outflow drops to the surface creating oxygen and you can see the air bubbles.
Thank you
