Tunze Flow Questions - AGA 120 - Extra Stream or Wavebox?

[dbranca]

I have an AGA 120 Reef Ready tank that has been running well for over one year now. The tank has dual overflows located a couple inches off each corner on the back of the tank. We use two 1" sea swirls (~1500 gal/hr) in the back corners and have mounted a 6100 in the middle pointing at the front of the tank just off center.

I am debating whether to add another 6100 or 6000 and/or a wavebox. I propose adding the extra stream next to the existing one and angle the stream opposite the existing one - angled a few degrees opposite so they both point towards the front glass a few inches from each other.

A. What would you recommend given these options? Two streams and a wavebox or just one 6100 and a wavebox?

B. If a decide to add the wavebox, does it have to be positioned on the side of the tank pointed towards the other side?

C. Using the original overflows and standpipes what would you expect the noise level to be?

D. The tank is one year old, how long before I need to be worried about the tank seam (silicon) strength decreasing to critical levels?

Thank you very much for your time!

What kind of corals are you keeping?

AGA makes a good tank and it is practically new, so assuming it is on a proper stand and level and hasn't been moved alot of times I don't think D is even a concern.

Just softies right now, but plan on SPS when I get a calc reactor setup. I have some large RBTA's which are my main concern. Thanks for your time!

The wavebox would be awesome for that. If you get one let me know if your bubble tip regains its bubbles. For the SPS a second Stream might be nice but I think the wavebox would be the way to go. It will make some splashing noise and the wave will be about 3/4" tall.

Thanks for your help!

If the tank is slightly not level would there be more of a concern for the extra stress using a wavebox? I can tell with my 120 that the water level is slightly higher on one side vs. the other. Just curious

Unlevel like 1/16- 18" no, but torqued is big trouble even without a wavebox.

 

[Evolley1]

The water level is less than 1/4", probably 1/8"

As I said, if it is just unlevel it isn't a problem but if it is torqued (diagonally unlevel) that is a major issue and the tank will fail eventually wavebox or not.
