yea even though I made it late and only got to talk to jake for a minute, can someone who was there for the entire talk put up a synopsis of what he was trying to convey for those of us that didn't make it!
Check out THIS article, covers most of it.
A big thanks to everybody who showed up. It was a fantastic meeting... Too bad Jake's presentation didn't apply to my tank as it's to smallBut I have some ideas about moving the powerheads tomorrow

You don't want to create whirlpools you want to create gyres. Whirlpools spin around the sides and gyres spin from top to bottom.HI All
Missed the meeting yesterday but after reading above article posted by smithcreek,are they basically saying you want to try and create a whirlpool effect with your water movement within tank
thanks for any input
You don't want to create whirlpools you want to create gyres. Whirlpools spin around the sides and gyres spin from top to bottom.
A gyre is Not necessarily top to bottom, but it seems like Jake thinks that works best in most cases. Makes sense since most tanks are set up with the rock along the back. At the meeting he did describe a couple tanks that he uses a whirlpool type gyre in. At least for me, his basic idea boils down to use your pumps to achieve "mass nwater movement". Make them work together to get all the water in your tank moving, more like a tide than trying to create a wave crashing random turbulence by pointing pumps at each other. However you can achieve it in your tank, top to bottom gyre, whirlpool gyre, is better than thinking about flow only as what actually comes out of the end of your pump.
I have a 92 corner bowfront and was never happy with the flow. When I redid my rockwork a few months ago I decided to try to create a whirlpool effect and so far I like it much better. The idea of keeping all the water moving is not new, I think it's just been "out of fashion" for a while. As Jake put it "random/chaotic" flow is what everyone thinks is "best", and his opinion backed up with some studies he conducted show that's not necessarily correct. When I decided to try a whirlpool it was based on an old build thread right here on this forum. I think it was a peninsula tank they wanted to make sure did not collect detritus at the far end, so they created a whirlpool. A top to bottom gyre would not work in my tank. I tried it to try to get rid of dead spots and keep detritus moving, but it was great to hear Jake describe some of the other benefits. After seeing his presentation I'm seriously considering buying a couple more pumps and a controller to reverse the flow several time a day.
Lucky me! I won the Maxi-Jet 1200 from the demonstration. On the way home went to Underwater World and picked up a 2nd one. I have the flow Jake was describing and I have to tell you it is intense. My sps came out very hairy once it was done. It is taking my lps some time to get used to it. I clearly had the wrong water flow in my tank. Great meeting!
