Is it safe to use mycorrhizal powders in planted tanks?

I have plenty around from my various other planting adventures and was wondering if it is safe to use in aquaria. The stuff does wonders for my terrestrial plants and would love to be able to use it to help my aquatic plants as well.

If you put mycorrhizal fungi in a fish tank substrate they will most likely drown and die. They need oxygen.

That is what I had assumed. I was just dreaming of a cheap alternative to bacter 100 or similar additives I suppose.

Cheaper = do nothing. The right bacteria will come into the tank on the plants, and on anything else that has been under water in any sort of aquarium.

If you specifically want to enhance the microorganism population, then research WHICH microorganisms you want to add. There are suppliers for almost all the different groups.

Nitrifying bacteria:
Look for a product that includes Nitrospira species of bacteria. Do not waste your money on any other 'cycle in a bottle' sort of products. If it does not include Nitrospira it has the wrong species of bacteria.

Decomposers: There are pond or aquarium supplies that include these, but these are among the most common bacteria. Why pay for what you get for free?

Beneficial bacteria that will out-compete fish-disease bacteria. This is an odd little corner of the microorganism world, and worth looking into. Snake oil? or the real thing? You decide. Research probiotics. Here is one such product.
