Hidden Tunze Stream

[wickedfrags]

If you intend on keeping a SPS dominant tank, at some point you will require high-flow powerheads that can be moved. SPS (and any coral for that matter) will eventually grow and obtruct flow, moving a powerhead to keep the flow effective is a good idea.

While somewhat unsightly you get use to them, and realistically most poeple will not even notice them. A closed loop is also a good option, however they generally provide less options to redirect flow as your tank evolves, or as you change the system. I have both a closed loop and 2 Tunze 6100's - each serve a specific purpose and I am happy with each of them.
