Greetings. I have been lurking around this group for well over a year now and I am finally about to setup my first hightech plant tank. Thanks for everyones' help and encouragement. I believe I will be able to have much happier plants thanks to you folks. Thanks again for sharing the information that I hope will make my plant tank a success!! --- David Holsclaw DavidH at Dra_Com "Never underpay your software engineers" - Jurassic Park Moral
