Deco Rock Placement

[npaden]

I searched the forum and found 1 reference to placing the Deco rock on the sand and that this wasn't a good thing for the pump.

How far off the sand do they need to be?

I have a southdown DSB and my sand "drifts" around when I make any changes to my water flow patterns, but it stays down pretty good.

I'm contemplating getting 2 more streams and putting them in deco rocks.

Here is a few pics:

Lots more pics here if a close up would help any - http://padens.com/files/tank pics 2-13-05/index.htm

I'm also gonna swap out the Reeftec PE-2 for a stream and get the new controller. Tank dimensions are 122x28x28.

I was thinking putting 2 x 6200's on the ends of the tank and 2 x 6100's in the middle of the tank somewhere with the deco rocks. Do you think that would work okay or should I just hang the 6100's on the sides of the overflows?

Thanks for any advice. I know personal tank consulting isn't your job!

I really have pretty good water flow right now but I think I can kick it up a notch and still keep my sand in the tank.

Thanks, Nathan

Hi Nathan,

I would say just put the Stream rocks on a couple other rocks, get them about 6" over the sand and problem solved. That is how I use them, I maybe put one easy to move rock on top of it to help blend it in but knowing the rock will have to come out for cleaning the pump.
