Ohh nooo!

Yes, copious amounts.

CRW. do you have a test kit?

Yea I think your water was toxic 20% every 6 wks is barely nothing

Thats what I have always done in the past with good results. What is the maximum for 55galtk, if memory serves me I think I was well under. What say you? Good info, Thanx Calvin

I wouldn't be so quick to jump to conclusions. Surprisingly enough, I've seen tanks go years without water changes, but the fish were healthy. I do agree that 20% every 6 weeks isn't enough.

Crw, I would start doing 50% water changes every week with dechlotinator if possible. That'll ensure your water quality is good.

20% is the prescribed amount or so I was thinking, never been a problem in the past, for the fish to go from healthy to dead overnight it seems something else is the culprit. Thanx

Do not have a kit and my water is not chlorinated we use well water. Once again this is the 1st time this has happened and Ive done this off and on for about 30 years. I have already disposed of the water and like knucklehead I didnt even think about a water sample. I thank yall so much for the replies, please keep them coming. Thanx Calvin

Well I guess I will start over, what would be best to clean the aquarium?

[CRW]

By this do you mean you bought a new filter or did you clean it?

Once a month I change the filter completely.Dispose of the old one, purge the new one and install.

[SunnyHouTX]

Was this tank indoors or outdoors?

[mistahoo]

That would definitely do it. It would work a few times, but buying a whole new filter will eventually kick up a "mini cycle" which would kill off one if not all your fish. Go buy an aquaclear 110 and you won't ever have to touch the filter again. Just don't use the carbon that's included. Keep up weekly water changes of at least 50%.

[SunnyHouTX]

And rinse out the innards with tank water ONLY every couple of months.

Just siphon the water out. You shouldn't need to clean it if it was already running.

Yup. Just vacuum out the gravel to take out any accumulated fish poop. Do this as often as you can when you do water changes.

Thats what I usually do. Like I said Ive had an Aquarium for some time now and have raised fish, but, Ive never had anything like this happen.

[CRW]

Think Ive figured it out...faulty heater, the water was EXTREMELY warm. The fish were blooted and smelled like they had been dead for several days. I noticed the smell when I came down and the water was very foggy, when it was clear the night before and the fish were alive. This is the only thing I can contribute it to. I talked to fellow today that had the same thing happen to him. Presently I am in the process of cleaning tank and will restart in a few days. Thanx to everyone for their response and help. Calvin

What brand heater were you using?
