heater?

[snazzyiron]

Hi guys,

I have a beautiful 12 gallon Marineland tank that has been very healthy. Only guppies are in this tank. No fish deaths for several months.

I received a letter from Marineland to recall my heater. I took it to Petsmart and they gave me a new TopFin heater. I put it in last night and today I have dead fish and seriously stressed ones. The live ones are hanging at the top of the tank and are probably going to die also.

My question is: The new heater must have caused these deaths, but how? Temperature is the same almost.

Any help would be greatly appreciated.

Was there a heater in the tank when you took the recalled one out and returned it? A rapid change in temperature could be the culprit. Another possibility is that there happened to be chemicals on the new heater. Did you rinse it thorougly?

I think you are right. There was a heater in the tank that I switched with the new one. I was stupid and I did not rinse the new heater before put it in. There must have been something on it. Anyway after multiple deaths, I think I have turned the corner. No new deaths today. And I rinsed the newest heater very well. I saw an earlier post that someone said TopFin heaters are death in a box. Well, it certainly was for me. I will now do several water changes (one a day) until I feel like my fish are ok. I lost 9 of my most beautiful males and several large females.

Thank you so much for the reply!
