But in a good way...

 

Not worried about the tank 'failing' at all. Using the 'wave' settings, the flow is both universal and gentle at the same time...

 

By 'universal' I mean that the water movement gets dispersed into such a wide pattern that the entire water volume inside the tank kind off ebbs and flows; there really is no one place where the current is stronger than another - the one exception being in the area immediately in front of the pump nozzle.

 

And by 'gentle' I mean that the flow pattern is repetitive in nature and not so 'chaotic' as other pumps.

 

I see a lot of people using these pumps in the 'else' mode. They say they are doing this because they want 'random flow' since they have read somewhere that most corals, especially SPS, need random flow. Except that's not really what is meant by the phrase 'SPS corals need random flow'...

 

What that phrase means is that, back in the days prior to all these prop - style pumps, you had powerhead - style pumps like maxijets that all moved water in a very narrow stream. So either your coral got a constant 'blast' of water current, or nothing. And we had to put multiple powerheads in the tank to create multiple streams; and we would aim them at each other so the streams would collide and cause the water in the tank to flow in more ways than just the 'constant blast or nothing' scenario. Hopefully we had a sufficient water movement that we didn't have large 'dead spots' and / or places where there was still a constant blast of water.. in other words, the water movement pattern was varied in nature at random locations in the tank. That's really what the whole 'random flow' idea is about.

 

Anyway, my point is that, on 'wave' mode the entire tank volume is ebbing and flowing so that the water current is constantly moving and varying in direction and force. Think about it. Water moves towards a location, then the wave causes it to move away from same location. Just like waves in the ocean (or at least  pretty similar).

 

IMO you are not going to 'beat' natural water movement patterns for  optimal nutrient delivery to coral and subsequent waste product removal. Honestly, I don't know why anyone would buy one of these pumps and then run it on anything but the wave modes...
