Hey folks I just had a heater crack and fall apart in my tank I was wondering if there were any toxic chemicals in Fluval heaters that would kill my fish over night. I just did a water change and am going to do another in the morning but if anyone knows of any toxins used in these heaters for one reason or another please let me know.

Are you using carbon in your filters?

just whatever is in the aqueon filter pads which is likely used up by now. I've seen NO adverse effects so far but I posted just in case somebody had any knowledge of what is inside these heaters.
