Wave and added stress

[grouper therapy]

Water sloshing back and forth, exerting periodic stress well in excess of the pressure of standing water (constant flow from a powerhead is irrelevant), will most definitely weaken your seals much faster than it would otherwise. I haven't tried it, but I'll pretty well guarantee it. I know from my work in the oil & gas industry that with the volumes of liquid pumped into and out of said tanks at high rates that this is a concern in the design and engineering of the tank both as regards its external structure but its internal geometry.[/QUO
Sloshing back and forth is a relative term. The volumes of water you reference being pumped in and out of a holding tank far exceeds a 1" to 2" wave in a reef tank . Why is the powerhead irrelevant it is moving water? Usually the source of the wave. Explain the difference of water pulsing against a glass panel at 27" at 12" and at 2" in an aquarium
Some have been running waveboxes for years now without problems.

The seams in all aquariums weaken over time even without water in them. The question is does the wave weaken them quicker and if so at what rate. Most aquariums never stay set up long enough to know. I think to know it would be a matter of calculating the displacement and replacement volume of the wave.

its amazing how small issues like this turn in to huge debate threads.

Yes a wave of 1" can hold quite a bit of power to it, but your tank is ALOT stronger then you give it credit for. The glass can handle the wave slap fine, the only thing under stress is the seams, which are silicon and flexible! Also you have trim on the tops and bottoms of tanks to hold them together! With acrylic, its plastic which is flexible and the seams are stronger then the acrylic. If the acrylic was ever stressing to the point of fracture you would see white marks and cracks form well before a failure.

Bottom line, there is ZERO evidence that this will cause any issues with a tank. If youre worried about it DONT USE IT! Waveboxes have been in use for over 10 years now. If they did cause that much stress on tanks you would have started to hear of tank failures by now.

Again there IS NO EVIDENCE ONE WAY OR THE OTHER! Until someone does an experiment on a few tanks to failure all this is, is an argument.

What are you an engineer or something?? :tongue:

I've seen tanks fail just because tanks that don't use wave boxes its a fact that the seams just don't hold up over time.regardless things are not meant to last for ever at least with silicone involved

Before I believed it did or did not make a difference. I would have to see a controlled experiment I agree that at this point it's pure speculation and until I see factual evidence that can prove this claim otherwise its a matter of opinion and personal experience.

Someone may have had a tank fail after a wave box but that still doesn't prove anything because the seam may have been weak and been on its way out anyway
