Why Vortech or Tunze over Closed Loop?

[builderguy]

I see a lot of high-end tanks using vortechs and Tunzes...why not closed loop given the benefit of not having pumps in the tank provided by closed-loop implementation and with devices such as OceansMotions you still get chaotic flow.

So why are so many choosing pumps in the tank over closed loop?

less electricity, you can move them around to fix dead spots , they dont leak, you get the upflow current from the pumps

Closed loops use way more electricity than in tank powerheads. Complexity of the plumbing, and the need to drill many holes are others.

 

[builderguy]

those were some of my initial thoughts...anyone else?

I think electricity and versatility without leaks would be the two big ones, but being able to adjust flow and use different settings is probably another reason.

Ability to generate random flow and play with toys.

I know someone criticizing me for wanting to put vortech and tunzes in my tanks. He said that my tank will look cheap by putting controllable tunzes and vortechs. I counter by telling him how much I paid for each of the powerhead and how I have better distribution of flow in the tank. Oh by the way, I also have a closed loop powered by a reeflo dart.

My biggest reasons are far less electric usage, far less noise from large external pumps, and wider more gentle flow.
