Thanks everybody for giving me those hints. I'll see what I can do to
augment the wattage in the tank before doing anything else.

Oh, and just as an add-on to the current conversation. I've known for
a while that my PH was too high. I've tried using something called
"PH Adjust down":

to reduce the PH, but that did not work at all. I would sometime
succesfully reduce the PH around 7.5, but less than 24 hours latter it
was back up to 8+. So I wouldn't be suprised that you're right about
my plants eating all the CO2 making the PH bounce back up very
quickly.

BTW, I've read this newsgroups, several websites and a few other
newsgroups and there's so many diferent opinion about this that I
don't know...: Is CO2 really a necessity in a tank if I want to
maintain plants?

Your pH is so high it's off my chart, but anything over 8 means you have
virtually no CO2.

I wondered if his plants were stripping all the CO2 out of the water, creating
that artificially high pH. (If so, increasing surface turbulence should bring
it down.)

But since he's got less than one watt per gallon, and says his plants aren't
growing well, I dunno...
