Ok here is the deal. I have had a large loss of fish and I don't know why. The water paramters are all fine I just tested them. I lost my entire group of wild caught Lemon Jakes, a large Syno. Eupterus, my male Albino Yellow Lab, my wild female Flavescents jumped out of the tank, and my wild male Borleyi up and croaked. I also lost an entire group of growouts of the yellow labs and white labs and around 8 blue eyed plecos. I have done nothing to the system except pull the UV sterilizer because it was leaking. Could that be the problem? These fish have shown no signs of disease. My albino lab was perfectly healthy looking, swimming and eating when I got up and I just went down there and he croaked. I took the female out and put her in with the regular yellow labs. I don't know what else I can do.
 
Wow very sorry to hear about this. I don't think pulling the UV would cause this bad of an effect, if any. Ecspecially since you said your water was fine.
 
Yeah but that's pH, GH, amonia, nitrates, nitrites, etc... What about the bacteria but on the other hand all tanks are run off a single pump and filter so how come it is only certain tanks and not all of them. The albino labs were on the top shelf, lemon jakes under them and otter points on the bottom. I haven't lost any otter points. I am confused and frustrated. Sucks to sit and watch fish die and be helpless to do anything about it.
 
Sounds like something's gotten into and poisoned your water, I'd do some large water changes and hope for the best. What are all your water params? Are you missing any fish (maybe one's rotting somewhere and poisoning the tanks)?
 
Good points above. How do the fish look when they die? Do they have the "open mouth" stressed death? Have you seen any die yet? Are they just hanging out around the bottom? Breathing heavily?....spinning?

It is really strange that as you said all tanks are ran off the same pump, but you haven't lost any from the bottom tank
 
The only dead ones that had an open mouth were the jumpers. The others looked peaceful and like I said with the male albino he was eating then just layed on the bottom dead, no open mouth and that was an hour later. I went back down and 8 more plecos were dead in the one tank but the two tanks below haven't lost any fish either. Of the 80 tanks in the system only four or five have lost fish. I clean everyday and have no spaces for a fish to sit and rot other than on the floor.
pH 8.3
GH 140ppm
CH 140ppm
Nitrates 70ppm
I didn't write down the amonia. Maybe my GH and CH are too low but how can some be thriving and breeding and those 4 or 5 tanks are dying? It blows my mind.
 
Sorry to hear about your loss..... that really sucks big time!!
Are your electric supplies okay.... I would just check if there's any loose connection somewhere in those tanks.
I may be completely wrong in my guess.... but since most tanks are fine and only few tanks are going all wrong.... also your water parameters are fine and there's no chance of fish rotting in there.
Also you could look for any poisonous element that got mixed in the tanks accidentally. It could be anything from detergent to some poisonous insect.

May be my input won't help you in anyways.... but lots of fish dying in a short time means something extremely wrong is happening... and I would have checked for these. Also water parameter problem wouldn't result in such a big loss and some comparatively stronger fish in a tank would still hold on.
 
Sorry about your loss i hope you figure out what happened...:(
