Fertilizer Comparison

The following table lists the elements contained in the more commonly used fertilizers for aquatic plants. Recommended doses and different dilution rates need to be taken into account when comparing these products. To facilitate the comparison of such ratios a second table was derived with standardized numbers based on iron content.

TMG: Tropica Master Grow
CSM+B: CSM is the trace mix described for the PMDD recipe (+Boron)

Notes:
- Percentages shown for CSM, Seachem and Tropica products were taken from the lable and/or website.

- Percentages shown for Kent products were kindly offered by Kent.

- CSM+B is in powdered form and the percentages shown are not diluted.

- To properly compare the ratios of elements between these products I have tried to standardize the values based on FE contents and recommended doses here.
