  1. Default Melafix causing bio-filter bacterial death and subsequent recycle???


    0 Not allowed!
    Hello, all. It's been a while. Hope everyone is well.

    So, I have a 2.5 gal hospital tank currently containing 2 corys and 1 danio (the danio was completely homicidal, killed all his mates, and gets along with NO ONE but bottom dwellers...he serves soley as a "poop fish" to keep the cycle going in this tank.

    The corys were thrown in about two weeks ago because my gourami in their 20gal nipped both of them. I have been treating them with melafix for two weeks and their fins are regrowing very quickly.

    Thing is, during the first week...all water tests were perfect besides the normal trace amount of nitrates. Now, at the end of the second week, i have a tinge of ammonia <0.25, 0-trites, and 0-trates. I suspect the Melafix might have killed off my bacteria.

    Anyone ever experience something like this while treating with it for longer than one week?

    NOTE: I perform 90% water changes weekly on all my tanks.
    20gal: 18 neon tetra, ghost shrimp
    5.5gal: 5 glolight tetra
    5.5gal: royal blue/purple butterfly rose tail betta

    when i had my TBs i treated the tank almost on a daily basis with home made melafix. even the store bought one didnt cause any harm to my bb. i think its possible theres another reason for the bb loss, possibly the water wasnt dechlorinated?

    Have you tested your tap water for ammonia?
    When I go fishing I just place a sharp rock in the water and sit there waiting for all the dead fish to float to the top... Kingfisher
    Brutal honesty will be shown on this screen.
    I think my fish is adjusting well to the four gallon, He's laying on his side attempting to go to sleep on the bottom of the gravel.
    Tolerance is a great thing to have, so is the ability to shut up.

    I can explain it to you, but I can't understand it for you.

    hmmm...it was definitely dechlorinated with prime. the thing is that it's a really small tank with a small and presumably delicate load of bacteria.

    how big was your tank that you treated for all that time and what was the filtration on it gallon wise?

    good call but i know my tap water doesn't have it because i've tested it. also, all my other tanks read perfectly and i change my water on all four at the same time. so it's not like something changed in the tap water, ya know what i mean?

    29g, but HB has a valid point. even if its never had anything before its possible you have it in there now, or had it in there.

    I lean to the thought that you've just overstocked that tanks filtration capacity. Its a small tank and prolly doesn't have much of a filter, and it only had one fish to start and added two so you tripled the bioload. I think a week is about right for the ammonia to build up to the point where you could see it, considering the water changes you are doing...I think the BB just need to catch up to the current bioload.

    i think the same after considering my theories and the advice here. i am ruling out the sudden ammonia in the tap water theory. like i said, i do my water changes all at the same time. i highly doubt the water company is coming into my apartment and spiking one of my tanks to drive me crazy!

    i'll go about this as a partial recycle and hopefully the melafix isn't rocking this small filter and killing my bacteria. probably will use some seachem stability to help build it up. so it can handle more than one fish when needed.

    Melafix is an antibiotic, and thus can/may kill various bacteria. That is what is is used for, to kill the bacteria causing the problem. It is not going to differentiate between bacteria.

    Of course, this may not always occur, as other factors are involved. But it is a possibility.

    BTW, I would not keep any fish in a QT to keep it cycled. If fish are being quarantined to deal with some disease or condition, the last thing they need is more stress from another fish, especially one that is obviously stressed out itself.

    Byron.
