Need a lil help with flow

RMD photography · 03/23/2016, 04:10 PM

So I have been into saltwater for several years, but have always had cube tanks. I changed over to a long tank and can't seem to get my flow nailed down. I have a 950gph return, a Jebao wp10 on the rear glass in constant mode, and a Jebao wp25 on each end running various wave modes through Apex. Both are about 2/3rd the way up the height of the tank.

My rock is formed in two pillars being higher in the back and tapering down to the front angled left. I have a photo from the front of the tank as well as a rudimentary topographical layout from above so you can see how things are setup.

I have a decent amount of flow thought the tank, I can see plenty of movement everywhere. But I am getting a bit of buildup on the sandbed in the area's I list on the layout as dead spots. There is still water column movement in those areas, but not sandbed agitation. And the middle front, I get too much current at times and it creates an exposed glass area in the sand. At first I had the powerheads pointing straight toward each other and now have then angled a bt toward the front glass, but still no change.

Any input on where to move the powerheads or how to angle them would be appreciated!

IMHO you probably have good flow, just add a few Nassarius Snails and they will take care of the algae in your substrate... The few I have work like bulldozers through mine...

I have a few Cerith's, so far all my lfs's have been out of the Nassarius so I just have a couple carried over from my old tank.

How can I change things to not blow my sand in front down to bare glass?

I would use a more dense substrate in the front... I dislike sand, but the last I bought was sand (although I thought it was not)...
When I worked at a LFS that did aquarium maintenance as well, we only used Caribsea Florida crushed coral in all of our tanks including customer builds... It is dirty but washes out nicely, and looks good as well...
