Every time I have a nutrient deficiency with my plants, I have to ask the same questions and I'm sure that a lot of other aquapons feel the same way. I thought, wouldn't be nice to have an…Continue

Has anyone tried glacial rock dust and/or Azomite? I found them to both be beneficial in the system used judiciously, and with no adverse effects to the fish.Continue
hi,i saw this video and wanted to share with you.
@john mark - Azamite is a clay powder. It's not very soluable.
i want to try azomite but i heard it will raise ph to high. i used laterite for freshwater plants in fish tanks. i am going to try that when i set a system shortly.
Thank you Jordan but this is not quite the confirmation I'm looking for. My goal is to find natural sources of various nutrients which can be supplied to a bioponic system. If we loose the ability to just order up a bag of Sequestrene 138 or 330, I would like to be ready with a backup plan.
FE2+ is one of the most difficult micro-nutrients to render, BUT I may be barking up the wrong tree.
It may be that the addition of organic acids would be a better way to help facilitate the conversion of iron by the plant it self. So rather than supply iron from kelp it may be that I should be looking toward something like humic acids.
So far the best alternative has been to chelate iron with an anaerobic condition. There is a whole thread devoted to it somewhere on this site but I can't recall the name of the method.
Jordan I'm sorry if I was not clear, but that's what I'm asking. Is the iron in kelp of an available chelated form?
Iron is typically added to the system in the form of Chelated Iron to supplement.
I'm wondering if the iron in kelp is readily available to plants.
