MitchM tank build

[mr.wilson]

The lids will raise the tank temp at least 5˚F. They will limit gas exchange slightly, but it isn't a major concern. You will get condensation and salt creep/spray and the lids will become cloudy further diffusing light. If you are using metal halide lighting, the lids will warp considerably. Flipping them weekly helps keep them straight.

Lol not recommending a pair of Abyzz with a controller just yet Mr. W? It's certainly not a cheap option.

That's how I'd do it. You could run them 100,10... 10,100 so the lines don't go stagnant.

Trouble maker!

Yes, I would use two Abyzz 420 pumps with a controller and call it a day ($4,800.00). You would do fine with two Abyzz 200s or even one if you tune it right. A couple $25 Eductors make it even more fun

Sorry, I don't care for the short mechanical wave action and I'm aiming for a more sustained water velocity of 15cm/sec in the mid and lower zones.

[mr.wilson]

The wave video is just a gimmick to show the possibilities. I don't care for the waves either. You can use two pumps on the controller as a closed loop, return pump or drop them right in the tank. You can run them at 5% to keep water moving through the pipe and at the opposing end, run one at 100% for your five hour tidal flow.

I agree 100% it wasn't designed to do that, just to show how using inlets and outlets correctly can greatly increase the flow potential, and to show that you do not need a dirty great big box in the tank to get far more movement than a wave box could ever achieve.

Plus the point that already having a Profilux the last thing I want to add is another controller.
They sound like great pumps.
I wonder if a Profilux could accomplish the same timing for someone that would want that type of water movement?

The lids are Lexan, so I am not expecting much, if any warpage.

Paul's adaptation of his Revolutions product to an inline solution for you is nothing short of pure genius. His best ideas are inspired from specialized requirements like yours.

Lexan will still warp. I have used lots of these lids over the years.

Remember those are the Seaswirl flow limits, not the limits of the Dart to push water through a Seaswirl.

I did a 600 gallon acrylic tank (96x30x48) a few years ago, using two darts on 2 OM 4ways, with a Blueline 100 return pump. Flow was excellent. Use an online head loss calculator to make sue you are getting the best out of your system.

Use threaded parts where you can so it is easier to adapt to change.

did you have that motorized valve on there
