Update... I have been busy with work and working on the tank. The people on this forum have been very helpful. Here are a few shots of the 29... It really is time for an upgrade it has been running strong for 18 months and in its prime it was a beautiful tank. There are also pics of the whole system the pvc overflow and the diy return spray bar.... excuse the awful caulking job. And the uneven holes in the spray bar... I figure it won't hurt it will keep the flow spread out. There is also a pic of the final piece of the puzzle the uv sterilizer. Some say unnecessary, however I really felt the need to have one. If it keeps my water crystal clear and kills off unwanted pathogens and algae, then it is only helping. I am going to get water in the system tomorrow making sure there are no leaks in the plumbing etc. I'll most likely have more pics then. I may also try to hide the return hose a bit better.
