So i mix it 50 / 50 with sand and i should still get all of the benefits from the Mud, i,e, Minerals and nutrients allong with the Ahem.. "miracle" part, (HLLD regeneration. And this should also help to stabalise the Macro's in the Refugeium.

well.. i have a mud filter sump/refigium, actually its all i have for filtration. i don't think mixing the mud and sand is going to work for a few reasons.
1) you aren’t really going to benefit much from the mud if its mixed with that sand. the water needs to constantly wash over it to release the micro nutrients.
2) the mud breaks down and you need to replace 50% of it every year. im not sure how you will do this if its mixed with the sand. im not sure but you may just end up with mush instead of a sand/mud bed. just a guess
i would say you should consider either/or. if you do do mud only you dont need a lot. my 90 gallon only has 20lbs of mud in the sump. less than 2 inches thick. and the mud leaches enough iodine that you don't have to supplement that anymore either.
