Using dry ferts

This is really interesting Jeff. Do you have any idea how this chart was formulated? IE/ Can we take it as accurate? It would also explain why many folks have claimed that Seachem Trace isn't that effective, as it looks to be a scaled down version of Flourish Comprehensive. Similarly with CSM+B.

I haven't found any info on how he came up with the #s. Maybe an email to him.

I have heard that its better to just do a water change then worry about adding flourish trace. Tap water contains more nutrients then it does

Here is a direct quote from the APD from Greg Morin about Flourish Trace. Seachem has never claimed it to be something you have to have. Just something that might fit a niche in certain situations. I just use Flourish myself and no other trace addatives.

Flourish' main focus is to provide a source of micro and trace organic (vitamins, amino acids) and inorganic (minerals such as iron, boron, zinc, etc, etc.) What we have learned in the subsequent years since we introduced Flourish is that the inorganic components (the minerals) are typically depleted much more rapidly then the organic components. This is attributable to both utilization as well as chemical oxidation and precipitation. That's why we came out with Flourish Iron first; in order to maintain iron with Flourish alone you may need to possibly add Flourish so frequently that the organics can build up to a point where the plants cannot use them rapidly enough. With Flourish Iron one can dose daily or every other day and still dose Flourish once or twice a week and not be concerned that the iron is becoming depleted before it is time to dose again. The same concept applies for Flourish Trace; it can be dosed more frequently than Flourish _if needed_. With Flourish Trace it is a little trickier because you can't test for the trace elements it provides (at least not easily!). So for Flourish Trace we recommend one try it in conjunction with Flourish for a month or two to see if they notice a difference in their plants. If so they should continue to use it, if not, then it may not be necessary as Flourish alone may be providing all that is needed.
