What do you plan on keeping in it?
In my 29 I HAD 3 MJ 900s (( plus the return )), tank is mainly SPS. I am messing with the flow right now, put an anemone in there. Right now I just have 2 Koralia 1s in there, still seeing what I want to do.
Put that seems like it might work, just have to see how your corals respond to it.

Depends on amount of stock , amout of LR , water readings. There is no sure way from tank to tank. You do want a cross flow though for FOWLR or reef. You get O2 exchange from proper flow and helps control nitrates. Look here.

The one thing that I don't like about the MJs in that size tank is the flow is so direct. When I had them in my 29, had to "bounce" the flow off the glass. Over all I like those powerheads, just need to make sure you don't blast any corals with them. Mine would push my anemone around too much.

In my 29, I have one Koralia1, plus my return. That gives me about 716 gph as it is now.
The tank is stocked with 2 colonies of zoas, 2 colonies of button polyps, 1 ric rock, 1 gsp, 1 candy cane, 1 torch, 1 pearl bubble coral and an open brain. Brain not looking so good..well, looks OK and I see his feeders come out, but it's not really opening up and "laying" on the sandbed...kind of cupped shaped.
Anyway, I was thinking of adding one more Koralia1, but was afraid of a sandstorm. Any ideas from anyone, or maybe go with a koralia nano in addition to my existing koralia1 and return?

I would not GO with #2 with the 29 gallon. MB 2 #2's on one side with one low and one mid facing the center glass and 1 # 3 or 4 i would go 4 on other side mid range facing center front glass. Dont under estimate flow. Like i said amount of LR and LS and rock placement help. With proper flow the LR will convert ammonia and nitrate into harmaless nitrogen and the SB will convert nitrate into nitrogen.But if flow is low they will only collect nitrates and ammonia and no longer serve as a bio filter.
I like to use the feeding method. Whene you feed add alittle extra and whatch how it flow around the whl tank.You want to see it stay in motion and suspended but if you see areas where it collects or seems to drop then you have low flow.
If you have rock that is packed and get no flow then no amount of flow will help.If you have little rock and low stock with rock placed lose and unconfined then the lower flow will work.
You need to adjust the flow to your paticular setup.A pic would really help.

I see red algea with bubbles in it. More flow will reduce and or eliminate that.You could add a better powerhead on the other side but it would tank longer. Clean the one you have to improve flow and add 1 # 2 below it as far back as possible facing the middle front glass.Same as the other.Then add a #3 or 4 on the other side for cross flow.
I like to use a powerhead with duckbill tip for dirrection control and a flow control know for flow control.Give a newbie much better control and are great for water changes.You add clear tube and drain and fill with it.http://www.drsfostersmith.com/Produ...e+matchallpartial&Ntk=All&N=2004&Ntt=rio&Np=1

Gotcha. The power head has been cleaned, several times actually..LOL! That's when the algae was really bad. It's much much better now, but still not gone.
I just want to make sure I have this right. I'm going to add a koralia2 to the same side as the koralia1, but lower and further back. The flow will blow to the middle front glass.
Then, I'll add a koralia3 or 4 to the other side of the tank, in the same position as the #2 that I'm adding?
For whatever reason, I didn't know I could go as high as 3 or 4's in my tank!
I really appreciate your help!

I can't speak for the 3, but I don't think you should add a 4 to your 29, just think it would be way to big and really stand out. I have a 4 in my 75 and while it isn't too big, it isn't hidden either.
You can see it on the right hand side (( top )) this is in a 4 foot tank.

Another great tank, Todd! I can only hope...
Sounds good though, I'll see just how big the 2 and 3 are. I know it's pretty easy to see my 1 in the biocube.
I have a custom 5g that has a nano and I just didn't think that would do much in the 29.
I'm presently in the process of trying to "win" my wife over with converting my 75 cichlid into a reef. I really liked the cichlid's until I discovered this addiction!
If I win that conversion right and start a build on my 75g, would you mind if I had any questions at that point?
Again, thank you very much.
