Brad,

now I dont know, but would it be a thing to put 2 pumps about 6 inches from your sand, and than put them on at least a 40 to 60 degree angle upwards,

I'm planning for my new tank as well, and as you know it would be in the 350 to 500 gal range, and proubably build out of epoxy, but still,

I was thinking of putting 3 low pointing up, and 3 ore 4 random (one left, one right and 2 from the back to front.

but maybe the upwards stream will give you more flow, without the shifting

wavebox
 

been running my wave box for 5 years on my 220.no problems at all.you can see the sea snow move around the tank.i picked mine up on e-bay for $220 from waterkei.outflow head is sitting about 10 inches below the surface and it is hidden by rockwork.it might be the reason i can keep carnations and seafans for years-with them spreading

Kevin, absolutely. The problem with the Tunze mounts on the older pumps I have, is that you can't aim them up or down. The new one work that way, but unless I find some really cheap, I can't upgrade.
I am thinking of adding a couple of maxijets in the back pointing up on an angle, I'm just waiting to see what the flow looks like when the new sequence kicks in at 1:30. Right now I have a nice wave, at only 0-30%. At 1:30, it jumps to 100%, so I'll be standing by with a mop :)
But yes, flow from the bottom up will help remove the "fluff"

Which is what I'm trying to do, right now it all settles out and looks like crap.

Ok, update. Surf's up in the tank, but it's not going over the edges. My old Tunze 6100 with the failing clip finally broke loose with the action, so I've re-arranged my sand a bit (a lot). Zap straps to the rescue, it's good for another 10 years. :) Let's hope this new wave doesn't break anything.

For those with Tunze and Apex controllers, it's pretty easy to get a wave without the box.

What type of Apex controller is the cheapest can I get for my Tunzes ?

No idea. Check J&L site for their options.

I think you can get unlucky with a tank with or without a wavebox. Honestly I think if a wb pushes things over the edge then there was a latent flaw to begin with. A 10% reduction in lifespan is a WAG at best. So 1 year out of 10 ... But who has a tank longer than 5 years anyhow n very few.

I was worried at first with my tank because I heard stories of plants leaves wiggling when left on the tank, but on my tank with 2 there was absolutely no movement to the glass from the wave.

What you do need to watch out for is the overflow height from the top of the tanks. A tank with wb should have a lower overflow.

My $0.02 anyhow.

Tony, there doesn't appear to be any movement at all, so not as worried as I was yesterday. My overflow is a foot long, centered on the back wall, so it's working perfectly. The wave is more a meet in the middle rather than end to end wave.
Problem now, the Tunze keeps squeaking randomly....:cry:

brad, i have a old clip for the 6105, if you need it, i have no use for it
