This is how I have my Vortechs... I'm sorry for the film on the glass but I ordered a new blade, salt, the Prodibio Bioclean kit and I was suppose to receive everything on tuesday but Canada Post got lockout...:twised: So yeahhh I'm mad.
The pictures were taken with my iphone :neutral:

I've got a tail spot blenny in a 20 gallon with an mp10 and the little burrow he's claimed as his is about 4 inches from the bottom of the pump. He never seems to even struggle against the pull of the pump.

I too have a hard time getting my head around a healthy tang not being able to cope with one of these pumps, but then again freak accidents are always hard to imagine until they happen.

I have the mp 40 ESW (60-70%) in my 72 bowfront for 2 months now. no foam mesh. no fish lost.

From the photo your pumps certainly appear to be positioned lower than I have mine. Looks like close to 12 inches down from the top? I just measured mine and the top of the dry side motor is about 4 and a half inches from the rim of the tank on the right side and the left side one is about 5 inches below the rim. Still think healthy fish of a reasonable size and cognizant of being in the vicinity of a VorTech should not easily get trapped. Cleaner shrimp, blenny & baby clown are smaller critters and perhaps just bad luck that they got too close at the wrong time. Might not be a bad idea to raise your VorTechs just a bit more. Aside from getting them a bit farther away from the livestock, it will improve surface agitation and as a consequence, better gas exchange/oxygenation. Downside to the increased surface agitation (on my system anyhow) is that it really messes up my once highly polished T5 & MH reflectors, can't get 'em clean any more, grrr... Will be switching to LEDs some day anyhow, no more reflectors.

as everyone has said, a yellow tang should not get stuck unless he was not good to start with or extreamly small.

the positioning shouldn't matter at all as I had 6 of thoes types in my tank when it was running, I am a big proponant that your flow should be spread over as much of the tank as possible as long as your sand bed will alow it. I had two right on the bottom, two in the middle and two towards the top as I had a bare bottom.

look for a healthy yellow that is at least 3" in dia. and you shouldn't have problems

Thanks again for all your replies... Well I have BAD news...
Just when things couldn't get WORSE... Not receiving anything of what I bought online for my tank or the present I bought my dad for Father's Day.. because of the Canada Post's strike (Thank you I'll start using UPS).
I just saw that my small Yellow Tang 2in.. Once healthy... has a few tiny black spots.. So I'm guessing it's black ich.
It's the 1st time in 3years with this tank that one of my fish gets sick :cry: and the worst part it's I don't know what to do!!! :cry: He seems healthy he's swiming, playing and schooling with the other fish like always and he's pooping huge green poop :mrgreen: He seems ok.. But I don't know what to do! I don't want him to die or my other fish to get infected! What should I do??? I don't have a quarantine tank :neutral: It's the black ich going to go away if I keep him "healthy" and well fed? And what caused this black ich outbreak?

SOS!!!

Give her a freshwater bath and the black ich will drop off.
What is the size of your tank?

I have a 90g tank
My Yellow Tang is quite small tho, like 2 inches?
I don't know if is Black ich.. he seems fine.. 2 days ago I added carbon and I didn't rinse it :neutral: Do you think it may be some particles of carbon? How can I tell if it's black ich or carbon? :surprise:

You really must rinse your carbon. There is a suspected link between carbon dust and HLLE. There was a study being done a while ago to validate this, but I haven't heard anything more since and I do not know the results. However, it's not hard to imagine that carbon dust could be very bad for fish.

Or just buy the Carbon from BRS that has minimal dust.

I don't rinse mine, what I do is just let the first few gallons of water run through it into a pale, and then when the water is running clear then I put the output back into the sump. In effect this is rinsing it, but it's much easier than trying to rinse it by hand at the sink.
