Alfredshouse is gone.....

The ammonia was at 0.0
Nitrate was at .8
I know it was alot of fish at once, but there were only 3 in there and I didnt expect them all to die.
I opened the FX5 and it didnt stink like rotten eggs, Checked it two weeks ago.
I did another water change tonight, I changed 50% and the KH is still high, its at 140, with a safe range of 100-125,

Im going to take my water to AA tommorow and get them to test it.

this may be a stupid question but whats the temp? Any chance of a heater malfunction?

alfredshouse · #3 03-17-2009, 02:52 AM

Tested for voltage in the water, none was found
Did a water change on Saturday.
Please give more suggestions, Thanks

how long has the tank been up?

alfredshouse · #5 03-17-2009, 03:29 AM

Temperature is/was at 79.6 and its been up since Feb/08.

tested the inliner heater and digital thermometer and they are working. I put another Koralia in this weekend, thought that might of electricuted everything, but nope thats not it either.

Your water parameters seem to be fine. At least not to the point that it would kill everything overnight. It almost sounds like you might have had a CO2 build up. Using a cannister doesn't agitate the surface so this might have been the cause.
Just trying to help narrow down the possibilities.

You keep saying Nitrate - which is not really toxic to fish.

If you say Nitrate (No3) being 0.8 - I think you mean Nitrite (No2) - which is very toxic.

Sorry about your loss.

It was just too many fish added at once.

Bummer.

Actually, nitrITE in marine aquaria is relatively NON-toxic to fish:

What is concerning is the presence of nitrITE in the water at all which almost always means that ammonia (which is very toxic) was there previously. There should be zero nitrITE in a tank more than a year old unless there was a mini-cycle - possibly brought upon by the addition of so many fish at once.

I believe that the oxygen deprivation theory may be correct especially if the FX5 was the only form of circulation: Lots of fish are added to a tank with poor circulation. This causes the death of the weakest fish which in turn causes a mini-cycle which kills off the rest. When you finally do the testing the cycle is at the stage where's there's a little nitrITE left and rising nitrATES.

Your Alk reading is actually normal.

^ I think fkshiu is on the right track. I don't think it was a single issue that caused the death of all the fish, but in the end I do believe the primary cause was adding too many fish at once...then the resulting lack of oxygen and (likely) ammonia, and who knows what else may have also played a factor.
