Do I have enough flow?

Yeah definitely, I knew about the voltage thing and made sure it was 110

Do you think that would work having one in the back center or do you think 2 would be better on either end of the tank

If I did that then I'd have 8000gph/106x turn over rate, that seems like an awful lot of flow lol

 

Where are your current powerheads located?

 

Its actually not an "awful lot" the ocean's turnover can be far greater on certain parts of the reef. i run about 108X on my biocube 14 and my SPS and Gorgonian love it.

 

I have one in the upper right hand back corner pointing toward the center and the other is on the left closer to the front pointing straight across to the other side

 

I'm sure there's a lower limit, but I think tank turnover can be somewhat misleading. Also, I think it depends on the type of SPS you're looking to keep. The more difficult acros and milles might take the 50-100x turnover, but I'm having good luck with stylos, montis, and bird's nests at 20x. It all depends on coral placement in relation to the powerheads.

I pretty new to this, so others may correct me, but I think what's more important for SPS is velocity and turbulent flow. I have the JBJ with wavemaker as well. It's working great for mixed reef. I keep the powerheads high in the tank and the SPS go in the higher regions of the tank where there's more velocity and random water movement. My LPS are in the lower half and see lower water movement. The wavemaker is important so you don't have constant flow from the same direction on the SPS as that can damage them too.

One thing you can try to get more flow with the JBJ is lengthen your pulse. I run on 30 second intervals. It takes a while for the stream pumps to reach full flow. I don't think you get there in 10 seconds.

Good luck. You can see a short video of a stylophora pistillata in the build thread in my signature. It's on page 8. It shows the high flow when one pump was running and then the gentle flow when the other was going.

 

I'm not planning on keeping any hard to keep SPS since I'm new to this kind of coral I'm going to stick with the easier kinds and keep the tank a mixed reef

So how do you have you JBJ s positioned in your tank? I'm thinking about moving mine so they are facing each other.

 

I have an odd geometry tank (corner pentagon), so my placement probably won't help you. For a rectangle tank, I would put them on opposite ends facing each other (or on each end of tank in rear corner facing opposite front corner) and go to a 30 second pulse.

 

I'll try that thanks!!
