These are trace elements, and there is no claim that any of them are available to the plants. Plants pick up nutrients as ions. Many rocks contain loads of these elements, but locked up in crystal formations, where they won't be readily available to plants.
When we refer to "nutrients", it is primarily nitrogen, potassium and phosphorous that we mean, since those are the macro nutrients.
Well, the product clearly says.. "contains all the mineral nutrients needed for aquatic plant growth"
If the nutrients were not available to the plants,, then I would expect growth to be poor, and many,many,folks would be complaining about the product when in fact, all I have found thus far indicates that most folks are pleased with results produced and as mentioned,,many others on planted tank forums claim to produce similar results with much less expensive ingredients.Why strive to produce similar results to a product that is ineffective?
For myself.. I am thus far pleased with the product and I receive no compensation, nor am I afilliated ,,with the company that produces this product.
I'm not easily baited by fix all products (ie) Cycle This,Stress that,Pima or Mela this, pH up and down, Bacteria in a bottle or bag,etc.
But from what I have seen thus far,, There must be something provided with this product that is quite beneficial to the plants I am keeping in my particular tank. (am aware that same results could be achieved cheaper)
Measured opinions are always a good thing in my view, and I will take on board those expressed while continuing to observe results.
Do believe I will visit www.aquariumfertilizer.com
to see about possible PMDD Pre-Mix to perhaps provide additional benefits for my plants.
Would welcome thoughts/opinions on any benefits that this may provide.
I am always reading,listening,and attempting to learn more,, and apologise if I have come off in a bad light. I was confused by the suggestion that the substrate I chose was next to useless with respect to providing nutrients for plants when all other info and results thus far suggest otherwise.
