Nora, For sources, check out Florida Driftwood's website at http://www.floridadriftwood.com/subcatmfgprod.asp?0=242&1=261&2=-1&6=1 I forget if I found out about Florida Driftwood from here, but I found the Aquatic Concepts website (http://users.frii.com/gbooth/AquaticConcepts/) to be very helpful regarding undergravel heaters and much else. I'm new to planted aquaria (with the substrate heaters, CO2 injection, and all that), so I'm sure others will have more information too (such as other vendors). I did set up a substrate heater which works just fine, but I must admit I haven't been able to have it on very much - my aquarium lights heat up the water so much that I can only rarely add more heat from another source. I'm going to need to install fans in my hood to try to keep the fish from cooking in the summertime. Given the heat problem, the expense wasn't quite worth it. If my house were actually colder I think it would be fine, and I would be able to get full benefit of the undergravel heating system. If you live in a warm climate as I now do, you'll want to keep this in mind in making your decision on whether to purchase the substrate cables.
