    What brand of trace nutrients are you using, A-hua? And, how much are you putting in? Also, what size tank do you have?

    Are you sure that it is made for aquarium use? If it is simply a trace element fertilizer, it could be that it is made to be mixed with water for watering terrestrial plants. Or, it could be made for the cultivation of plants that grow in water. It may not be a good choice for aquariums.

    Aquarium use generally expects that you actually want to keep your fish alive.

    Hydroponics use generally expects you want your plants to grow well, well being of other inhabitants is secondary and/or optional. Hydroponics is generally for either food production or ornamentals so they don't really worry about the other animals that might be sharing the tank.

    Try to get the analysis for the product and post it. If you don't know what's in it, then you don't know what you're dosing, so there's no way of telling if your plants are even getting what they need. It's also hard to find out the cause of the problem too.

    Are you sure it is trace elements? It appears to be a precipitate and this could happen with an NPK macro mix.

    What color is the solution of this "trace" when it is premixed? If it is not rust colored, it is not a trace.

    FWIW, I use a hydroponics trace mix. But I also know the composition of everything that is in it.

    Give us what is written on the label.

    above are what i dose...which is wrote in chinese :D

    the words on pic 1 means...
    trace elements
    make good in plant grow, prevent fruitages fall down early, extend the time of fruit preservation, use less on new leaf or too hot,50cc /1000ml on hydroponics.
    put on airproor and cool place.
    500g
    ......that is all

    pic 2...
    color of trace

    pic 3....
    sediments(?) on bottle cover

    in fact, i used it because it is cheap(500g / 6.2 us dollors), and did not know what is inside(it do not show,too). it is different for me to analysis or sent it to the lab...

    beside during the 1 year i use the trace, i did not lost any fish because of it.

    the local chemistry store should know what is in this, or probably can find out.

    Ya... I'd suggest a fert change. Windfall isn't so much an issue with rotala. :D

    They aren't telling you what's in it, which is a big issue. It isn't meant for aquatic plants as well, which makes for an even bigger problem. The nutrient levels and related chemistry may be very wrong for aquatic plants, harmful to fish, and you've got no way of telling if or why besides experimenting.

    TPN, flourish or CSM+B would be good alternatives. If you can't get these, there are alternatives in most other countries as far as I know.
