Re: NANFA--Filters, 1/2 full large round tanks

Okay thought about this a little bit more... What would be _really_
interesting is setting up the various tubs with different configurations and
running a bit of a diagnostic on them as you're accomplishing what you had
originally intended to do. I don't intend to make more work for you... It'd
just be cool :)

What I don't like about bioballs is... They have this tendancy to
conglomerate detritus in a completely aerobic fashion, without any chance of
compaction into anaerobic situations where the trapped detritus _might_ be
of some use. By the time that happened, the nitrate wastes in the system
would be so high, there'd be no point in keeping fish :) The towers also
seem to blow off a lot of _useful_ CO2 that can translate into plant cells,
which again, translates into more biologically active surface area,
additional nitrogen conventered into plant matter and etc on ad nauseum.
I'll just stop there cause if I haven't gotten this whole point across,
there's no sense in repeating it :)

I'm now reneging on the idea of the mechanical removal of detritus weekly.
Again, you've already placed effort or expense in creating that detritus...
There's a bunch of biologically available export mechanisms to make use of
it, instead of waste it.

I won't even start on the economic realities that you might have with the
plant product... "Poop for Dollars" might express that idea well enough

And what's even cooler than that... I was just laying in bed thinking about
all this and I might someday soon have the opportunity to get someone to pay
me to play these kinds of games, and think these kinds of thoughts, and
space where I don't get told "you can only have three tanks Todd". Does the
University realize what they're getting themselves into? ;)

Okay enough time typing at the mistress... Back to the wife....
