Skip the WD filter, these went out wth Noah and his ark.
LR is all you need for decent filtration and IMO a bare base or coral
rubble is easiest.
Get a big sump instead of your proposed WD filter.
In your sump you should plan to have a real good protien skimer and an
algae refugium or algae filter of some sort (do a search on ATS (Algae
Turf Scrubbing) if your not familiar with the concept.
also make sure you can put enough water through the overflow, a decent
reef tank should have something on the area of 20 times the tank
volume, and put at least 10 times over the weir.
I'd suggest a min of 1 x 40mm (1.5") overflow.
Have fun and go slow, ask q's and wait for answers, don't listen LFS
advice, it's generally very poor and sales orientated not aquarist
orientated.

I will be attempting to setup my 75 gallon tank in a couple weeks. I still
am up in the air about SAND or Crushed Coral. I like the look of sand but
have been told that after a year or so you will have a bunch of trouble with
the sand. I guess because of all the stuff dieing in the sand it starts to
create a problem. Crushed Coral on the other hand can be vacuumed out at
every water change. I am going to let the opinions of this post influence
my decision. SO SAND OR CC???? I am going to have a combination of fish
and live rock. I plan on starting up the tank getting some live rock and
then letting the tank run for a couple months before adding any fish.
Another area I could use some help. I have an Amircale wet dry going in to
a reef ready AGA tank. I am not to sure how to hook up all the pvc plumbing
stuff. Does anyone have a diagram I could follow? I assume that one of the
pipes goes to the top of the W/D were the bio balls are and the other goes
back to the tank from the submersible pump. If anyone has any advice they
could give me PLEASE DO. I have been reading a fair share of books but
still have a lot of questions. I also will need to find a Local fish store.
I will be moving in a couple weeks and have no idea what is around me. I
will be in the Swedesboro area if anyone can help with a store near me I
would GREATLY appreciate it. THANKS for any help BILL
