Try asking this on the Central Cichlids list CentralCichlids@yahoogroups.com. I know of several people there that have done exactly what you ask. They can give you advice on how and what to do. I also think that Dan Woodland has a web page up where he shows what he has done along with Eric Hanamen. I have seen Hanamen's room and it is very nicely done and I am trying to replicate some of it in my garage. The concept isn't difficult but a picture is much easier to see what it is rather than try to explain.

Does anyone have any plans or suggestions on how to build/set up some type of central automatic water change system on thanks that cannot be drilled? I would appreciate any suggestions, ideas or helpful web sites that may help me accomplish this task as daily water changes now are getting old quick!
