Red Dragon pumps = silent:mrgreen:

True, but at ~$1000/pump it can get pricey pretty quick :mrgreen:

Well not quite but your right at $599US they are pricey. The only one I have is on my BK skimmer and it is certainly dead silent and I believe are very good on power consumption as well - I just don't pay attention because really it is minimal savings when you are running a bunch of Halides.

Giz,

Was over on RC just now and ran across a post by Rich Durso. The name sounded familiar, so I clicked on his website icon and found something that may quiet your tank (with pics!) ....

Thanks Bev,

I was planning on using a Standpipe, I use one now, but it doesn't stop the noise of the water crashing into the sump :D (I've come up with some ideas on how to quiet it down) But the main reason for a backroom is astetics(sp?) I have a ASM G3 skimmer, and all those "cool gadgets" to go with :D

I do plan on aquaboarding the whole room and sealing it afterwards as well. I have a dehumidifier and heater/ac unit for the room. Thanks for the input guys, keep it coming!

Thanks beermaster, I really look forward to living in a quiet city.

I talked with Brian over at AI tonight and we laid out the specs on the tank:
280G 72x30x30 Main Tank
Euro Bracing
2 overflows in the corners in black plexi
4 returns 2 at the top and 2 half way down
2 drains 2" w/standpipes
90G Sump with trickle filter (to start) with inline pump.
Steel Stand @ 48"

Just thought I would share.

Why a trickle filter?

I would use a single overflow with two 1.5" durso standpipe drains and one 1" return. Then just pump 800g/hr or so through the sump/return pump. This way you have a backup drain in case one fails. This would free up space of not have two overflows as well. Then drill the tank for a closed loop, and use a big ass pump of your choice for your main flow. Dont try to do too much flow through your sump/overflows, you will get excess noise and microbubbles.

If it is behind a wall, might want to look into a return manifold, I am happy with mine, I run 7, 1/2" nozzles off a 4500gph pump, gives me all the flow I need, and with loc-line I can adjust the flow easily to adapt to coral growth or new corals.

you realize that 2 returns halfway down will flood your sump unless you use check valves hey? and check valves suck. im also not clear on why use a trickle filter? i would kill the trickle filter and dump into a micro sock > skimmer > fuge > return. also any plans on a ocean motion and a closed loop?

If you still go with the returns, use two check valves, in case one fails you dont want to have a flood. If possible use a closed loop and avoid that problem all together.

For a Custom Tank if you can provide very detailed drawings Aquagiant makes a nice product...Just make sure that your drawings are very detailed.
