Hi,

It's been about a year since I set up my 75 gallon reef tank (some pics
at http://www.spazthecat.com/iblog/B93549880/index.html) and I was now
looking to optimize anything I could. So, I was looking for a little
advice as far as what I should do first.

My set up is as follows:

-75 gallon tank
-10 gallon sump plumbed to basement
-sump return pump is a Mag 1800 (distance of sump to main tank is 10-12
feet)
-1 Seaswirl on the the return line.
-1 Maxijet 600 at the end of the tank opposite the Seaswirl
-2 250 watt heaters in sump
-1 AquaC Urchin skimmer in the sump
-2 175 MH lights (10,000K)
-1 96 watt pc actinic
-75 lbs lived rock
-3-4 inch sand bed with sugar grained sized sand

Livestock:
-2 percula clowns
-1 yellow tank
-1 bartlett anthia
-1 orchid dotyback
-1 red and black cucumber
-approx 20 astrea snails
-approx 20 blue leg hermits
-approx 5 turbo snails
-unknown number of nassarius snails. Maybe 5.
-1 emerald crab
-green star polyps
-assorted mushrooms
-two plate corals
-1 tree coral
-large clump of Xenia
-yellow polyps

Care and feeding:
-5 gallon water change every two weeks. (IO salt + RO water)
-Buffer and calcium as needed.
-DT's Phytoplankton 15 ml every other day.
-Frozen food (Reef supreme), 1 block every other day
-OSI flake food on the days I don't feed the frozen food
-Nori, 1 strip every other day
-Tank chemistry has been stable

I think at this point the big thing I am missing is high enough water
flow. I was considering adding a SCWD instead of more powerheads. I
don't like to have extra "stuff" in the main tank.

Anything else? Suggestions?

Thanks!

Andy
