Cichlids dieing

There's the problem I do believe, about 3 years ago I goofed and lost track of how much stress zyme I put in and it was too much and in about 3 hours or so after disaster hit, as fast as I could pull fish out of the tank others were dieing, out of 23 fish I had 10 casulties and it was right after I had did a water change and added it


I really hope that's the rootcause, atleast I will be able to fix the problem. I will quit using stress Zyme. Should I also carefully measure how much dechloronator I am putting? cause I usually put a cap full everytime I do a water change (approx 30 gallons) and a capful is recommended for 50 gallons.
 
MAYBE ,SMALLER WATER CHANGES ?
TOO MUCH, TOO FAST ......SLOW EVERTHING WITH FISH ;-)

I guess you're right. I probably will go back to 25% water change every week. The only reason I went to 50% was because it read in one of the forums that it's better.
 
Do the 50% per week! If the water is the same temperature and 'mix' unless you are creating Niagra Falls every time you do a change, the water changes aren't stressing your fish and causing health issues.

Don't be so quick to throw out good advice - you should do 50% in every tank at least per week. Not only are you getting rid of nitrates, but all kinds of pathogens which get into our tanks through the air. Molds, bacteria, etc all will grow to dangerously high levels if you don't keep on top of water changes. It is the best thing you can do for your fish.

I will stick with the 50% water change. I use a small hose which is connected to my kitchen sink that way I can control the temperature and also the flow. Ofcourse I put the dechloronator before adding new water. The only thing that I will get rid of now is Stress Zyme. Hopefully everything will be back to normal.

Thanks everyone for the support and good advice. This forum rocks.
 
Not a good idea to use water from the hot tap...Your hot water system disolves minerals from the copper tubing and can harbour some nasty bacteria. (Thats why you shouldnt use the hot tap to cook with or make tea/coffee. If it can affect humans imagine what its doing to a sensitive semi-closed system like an aquarium)

You have a valid point. Is there a recommended technique to add 30 gallons of warm water without using a bucket? Since I do this weekly I am trying to find a faster way and thought that one from one heater would work, but I guess I have to find an alternate technique.

I use a bucket from the hot tap. I have no issues. I don't know what your plumbing is like though (or mine for that matter - never considered that copper pipes might be a problem)
 
I'm in a 70 year old house and always use warm water including water from the hot tap. Most dechlorinators allege they remove heavy metals, and the warnings not to use hot water for cooking or drinking were related to a much older generation of water heater than most of us likely have.

I highly doubt that's the problem. The Stress Zyme could be it, but any chance you found them acting strangely in the morning? I'm wondering if some of your now sexually maturing fish are being aggressive after dark - you have a lot of fish in your tank and I can see internal injuries as a possibility if someone is chasing them around after hours. Then again, I could be flat out wrong.
