|  FISH DYING AND BREATHING HEAVY So on another thread i was reading about some one who had added new powerheads and his fish started dying, same thing has happened to me when I added 2 new powerheads, all parameters are fine so I thought it was just a bit of sediment that the powerheads had stirred up because there was a bit of a film on the top of the water.  But in the thread some one said that there is a harmful coating on some powerheads and I should run them in vinegar and water, I'll do that but in the mean time can I set up my new skimmer without there being a coating problem??!! HELP PLEASE!! I have done about a 40% water change since all this started. |

|   Whats your temperature, power heads increase the  temperature. |

|   what type of powerhead is it?  could there be some electrical leak into the water? If they are made for aquarium, they should not have any dangerous coating, at least I hope! I use koralia and never even washed them prior to putting them in the aquarium. |

|   If the new powerheads are stirring up the sand, it could be releasing toxins that were trapped under the sand. |

|   I run 5 Koralias in two tanks.  Never heard of a coating issue.  With any brand for that matter.  Good luck.

I would not. I would probably moan and complain, read three words and swear once or twice. But since you made it this far, please rate my builds.   |
