Safe guarding fish against Vortech properller

same here. I have neon gobies and other small fish as well with no issues. I have even had an anemone get on one but survive just fine. When I opened a new pump and saw that foam covered, I couldn't help but think that would get filled up with crap from the water column, especially food. In my case with a deep tank, it just doesn't make sense.
 
I had a lawn mower blenny swim directly into the prop, he got spooked by something it wasn't a pretty sight.
 
I just lost a sailfin tang to a vortech as well. I found the tang glued to the side of the vortech when I came home from work. Mine are on pulse mode at 100% flow.
 
I have a hard time believing that the Vortech did it, but I have now read this several times. Even a reef keeping buddy of mine found a tang on one of his. I told him it couldn't possibly be the pump, but it's getting harder to argue that case.
 
I've seen it happen on MaxiJets & Tunze Streams. I'm sure it has happened with Korallias, Powersweeps, etc.

That being said, I've had cucumbers climb up the glass and work their way around my VorTech and not get sucked in. Trust me, I thought about moving the cucumber a couple of times, but decided it would be fine.

Can a fish get stuck? Yes. But that could happen with any pump, and pretty much has. It hasn't happened with my VorTechs, but now that I've posted it you watch.... :eek:
 
yeah, you just jinxed yourself Marc! Just seems strange to me since the input is so spread out. Maybe it's just stupid fish.
 
Just a Thought...

Just a Thought...

Barry called me last night to let me know my thread had been closed, and he also mentioned that he had lost a seemingly healthy foxface to one of his Vortechs. As I was steaming about the trolls that got my thread closed, the thought occured to me that perhaps the damage to my tank and these bizarre fish deaths might be related.

I have been very skeptical about fish dying on the Vortechs based on my own observations but there may be a link. If you look at the damage to my tank and understand that there were other pumps running set at the same speed in exactly the same environmental conditions, one can easily conclude that this pump must have ramped up beyond it's safe operating temperature and speed.

So what if this is happening to other pumps? Let's say that everything is running along fine, and some sort of code anomoly happens and the pump suddenly over-clocks. Eco-tech limits the motor speed at least in part because of temperature, but if the pump were to malfunction and suddenly ramp up, wouldn't that be cause for fish getting stuck on them?

This is by no means an indictment, but perhaps just a kernel of a theory. We know that there were code issues with the MP-40 so maybe this is a similar issue?

I guess the thing to do is to have people who have lost fish to their Vortechs to inspect their tanks for any signs of heat damage. I would suppose that nothing would be evident on glass, but perhaps on acrylic tanks we may seem some hazing or crazing, which wouild then be confirmation that the pump ramped up.

If you have lost a fish to a Vortech, please check the tank area and post the results, including type of tank, whether it is an MP-40 or WWD, and what if any damage is visible.

This way we may be able to help others as well as Eco-tech determine why this has happened so many times.
 
I saw my CB get plastered to the side of the pump once. Pulse mode at 100%. When the pump finished the cycle, he swam off like nothing happened. It was kind of funny actually.

What wasn't so funny was a newly acclaimated RBTA was pureed to nothing more than two small chunks. It clouded up my tank and there was slime everywhere. I had shut the pumps off to let the RBTA find a spot to attach. Once he attached I turned the pumps on the lowest setting in lagoon mode. He must have decided to let go in the middle of the night and the next morning...well you know the rest.

I'm not blaming the pump for that. I'm blaming knee jerk impulsive buying of livestock for that one. I do know that having a 'ton of flow' (and especially with these pumps), my livestock choices can be somewhat limited. But the positive affect these pumps have had on the overall health of my system overshadow any limits to what I might be able to put in the tank.

A pump cannot suddenly overclock.

There is no way for a VorTech pump to ramp up in speed beyond it's current max speed cutoff, nor is there anyway for the pump to ramp up to a point well beyond our thermal cutoff. Marginal increases above our temperature cutoff (60deg C, as stated on our webpage and in the instruction manual) are potentially possible.

The technology used to control the pumps is solid-state; aside from standard material tolerances (which could cause one pump to potentially run a bit faster or a bit hotter), there is no way for a pump to go above its maximum speed.

You were lucky then. My tigertail climbed onto the intake shroud and was literally pulled through it in 1/4 inch slices. Kind of like this:

magic chopper

A pity, really, as I've otherwise been quite pleased with the pump and my tank has benefited from the extra flow.
 
Hal,

Cukes and anemones are at risk in any aquarium with any powerhead, I wouldn't get too down on the VorTech for this reason.

yea tell that to my puffer, my pipe, my damsel, my cardinal and my anthia. all lost to a vortec. [profanity] overpriced death trap.

FYI,

I lost a nice BTA to my koralia. It's always a risk when you add a powerhead and things that like to move.

Oh, I understand the risks only too well unfortunately. I never expected my cuke to be that high on the glass for one thing.

I'm not ranting (I hope), just expressing one situation that ran contrary to what Melev had.
