I forgot to mention I have exactly 2 watts/gal in the form of an 15" 14W Triton T8. I also run DIY CO2. Water's soft at 4 to 5 deg. KH and 6 deg. GH; pH with CO2 added is about 6.4. Anyway, the question is what plants will "fit" without constant pruning. _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com
