tank is an Oceanic 120, set up in august/september of 2002. I intend it
to house primarily sps, along with Ricordea florida, a few Sarcophytons
and any other interesting organisms, and house a moderate fish load.
The main return from the basement sump is a Sequence
2900 SEQ21. The tank was intended to be a custom setup with 2 holes for
1.5 inch pipes contained in a single oversized overflow box. Unfortunately,
when it came it had only a single hole drilled in a single box, less flow
than a standard Oceanic 120. As a result, I have had to cut back on the
output from the sump and rely more heavily on closed loops and in-tank
circulation. This is probably more economical ayway. The Sequence puts
out a ton of water, and I have the ball valve after it practically closed.
circulation is provided by a Gemini pump set on a wavemaker that shuts
it on and off every 3 minutes. My Gemini is kind of noisy, but I have
seen other people with silent ones. Opposing that is a Tunze Stream 6060-
the lowest output one they currently make. This is on in the day and off
at night. Provides possibly more flow than the Gemini but cannot be operated
on a wavemaker. Very nice appliance. The Gemini shoots out water at such
a velocity that it creates a wave that sloshes up onto the crossbrace.
I slowed it down a bit by putting a larger pvc fitting around the outlet.
This slows the flow by inhibiting water from flowing in from the back,
kind of like a reverse eductor. Both units are screwed to the canopy.
Additional circulation is provided by a 3/4 Seaswirl driven by a Mag9.
This doesn't do much in comparison to the other two, and I will probably
switch to a bigger pump eventually.

Bluewave ballast. Really like these Reefoptix III fixtures. The PFO stuff
is from Premium
Aquatics, the other from Ecorals.
All in a homemade hood with a 4" Radioshack fan, blowing in. The
back and top is mostly open.
The sump is located in the basement for summer cooling and noise/mess
reduction. It is a 75 gallon Rubbermaid stock tank from a local feed store.
It has about 5 or 6 inches of Southdown sand in it, and is illuminated
on a cycle opposite the main tank (RDP) by a 250 watt incandescent plant
light. Floating in the sump is a ton of Chaetomorpha, spaghetti algae.
