Thanks! It's good to be back. I'm amazed at the changes. No more substrate heaters, VHO, or metal halide. Now it's CFLs, T5HOs, and LEDs! I also think the "new" rimless tanks are ironic, because everyone used to say that my DIY tanks were ugly because they didn't have any rims! (I used to scrounge for old storm windows to make small fry tanks for my angels and mbuna).
