See below...

The 75 gallon is 5 40 watt GE Daylight ultras ($6 a Home Depot or Lowes).
The 30 is 2 30 watt GE Aquarium lamps you get at the LFS ($12) and one 20
watt GE Plant/Aquarium lamp ($6 at HD or Lowes).

Filtration on the 75 is an Eheim 2217 and a Second Nature WDF something or
other. The one that has the cup like floss cartridges and the real sponge
as the last stage (not the drop in like the Whisper 1,2, 3, 4). I like both
of these because they catch plant matter and poop and keep it right there
for the bacteria to work on :) The turbulence is created by the canister
and is done without disturbing the surface.

Filtration on the 30 is an Eheim 2213 which creates a considerable amount of
turbulence in that tank. Additionally, I have a Whisper 1 running open to
blow food off the surface and put carbon in when I think it's necessary
(which isn't very often after the tank is established).

I said that all wrong I guess. There is a considerable amount of Flourite
mixed into the sand. I did 3 bags of play sand and one bag of Flourite in
the 75 and it seemed like a reasonable mixture. The Flourite on the surface
is just for aestetics.

Please be skeptical, not critical :)

You bet :)

I hear you there. Flourite is ridiculously priced. I've known people to
use Profile, which is a garden pond planter gravel rich in iron. I think
Sajjad was using this? It's a heckuva lot less expensive if you can find
it. Like $6 instead of $19 for a similar sized bag of Flourite.

I got tanks, sumps and pumps... You got space and electricity? It is a new
year, you know ;)
