    Re: Water problems...

    fish such as feeder goldfish have been exposed to a lot of bacterial strains such as aeromonas and have built up an immunity/resistance to the disease and although they may not show any symptoms can be carriers. the tilapia have possibly not been exposed to the disease and will succumb to it.

    the hatcheries use a lot of antibiotics to keep the fish alive and the strains of bacteria that the fish carry are many times are resistent to different antibiotics.

    there are aeromonas strains that can wipe out a hatchery in a very few days. anyone that remembers the angelfish/discus plague will know what i am talking about.

    i believe that if you bought the goldfish at a top quality KOI dealer that you would not have that problem.

    Bought them when they were about 3/4 to 1 inch long from PetSmart. They are now 4 to 6 inches long and have had very few die. I guess I'll take my chances with the tilapia and see what happens. Thanks

    The probability isn't 100% and I don't know what the pathogen is. No way for me to tell you how long or what to do.

    Thanks. I put them in this afternoon. Time will tell how long it takes before I start to see problems. Maybe I'll get lucky and they will survive.

    Anytime you ck Ph from tap aerate it first to stabilize gasses. O2 raises Ph, co2 lowers Ph. A closed system should read lower then fresh water because of the bioload. You probably knew these things but they can catch you.
    Hope your fish are doing ok.
