Re: Diskus Trace - Fresh Trace Thank you for your question. Both of these trace element products contain those elements that have been proven necessary for fish health and growth. If you can no longer get Discus Trace, then switching to Fresh Trace will ensure that your fish are being provided the trace elements that are constantly depleted out of the system. Like Discus Trace, Fresh Trace is a well rounded trace mineral supplement that does not contain sodium and is used to replenish trace and ultra trace minerals that are demonstrated to be necessary for fish health and growth. |
