closed loop spray bar

[celstar]

Has anyone used a very long over 6' spray bar on the bottom of the tank to spray around and through the live rock? If you have, please let me know if it worked?

I am curious as well. I was thinking of doing this to help with lower circulation. I plan to run an 8-way and possibly a spraybar off of a Hammerhead in my new 240.

Attached is my layout. The only thing that has changed is that I am doing away with the Wave2K unit.

It's not a spraybar per say, and it runs off my return, but here's my sloution for flow at the bottom. It's over the back because my tank is not drilled, but should work just as well with a bulkhead.



Here's what it looks like in operation...

Just following along....I am looking to do the same thing

How do you prevent the sand from blowing around?

I have a little over six feet of 1" pipe as a spraybar in the back of my tank. Drilled with 3/16" bit every inch or two.

This is fed by a hammerhead that also feeds a 1" sea-swirl. The line to the sea-swirl is throttled slightly with a ball valve. I get decent flow across the bottom, it definitely can push sand and small bits of rock/coral to the front.

[Edit: I don't have sand, so that's why it doesn't blow around. Sand from rocks, dead halmedia, or whatever just moves to the front and spins in little cyclones until I siphon it out]

I am sorry I was asking reverendmaynard how he prevents his sand from blowing around.Looking at the picture he has a spraybar running underneath the sand.I can not fiqure how it works.

Gudwyn what do you have for substrate by the way or are you barebottom?

Especally further down the page there are some nice pics how this guy did his closed loops. I get my tank two-weeks-tomorrow and im going to use this as the basis of my in-reef spraybar I think :-)

It's not a spray bar. There are 9 distinct outlets. The 2 at the top, at the ends of the crossbar, and the 7 that stick up, out of the sand. They are about 1/2-1" out of the sand. You can see one of the nozzels silloueted (sic?) nicely in front of the rocks in the lower left corner of the 2nd pic.

I don't lnow if you can see the spray bars but hear you go

Rockstar-
What kind of pump did you use for that? It is very close to what Im looking to do. I like the setup, nice work!

I am running a spraybar in my 250. I twisted the tube so that the holes (water) flows out at about a 5 degree level and sand has not been a problem
