I have (not particularly regularly) added some Tropica root tabs under the sand. I have recently come across the Easy Life range which seem to be pretty good and are a fair amount cheaper.
They do some root tabs and when I asked what they were composed of I got
If I have read https://www.ukaps.org/forum/threads/clay-balls.48828/#post-479609 correctly the iron oxide would only become available to plants if the substrate was anaerobic?
This is going back in time but I am sure that when I setup the tank I only used about 5cm of substrate (and probably more like 3cm at the front) to ensure I didn't get any anaerobic spots as I am sure the masses told me this was bad.
Would these be pretty much useless as a source of iron in my setup?

Root Sticks are made of baked red clay, without any added chemicals like chelators.
It contains mostly iron oxide (about 8,5%), some manganese, molybdenum, magnesium and potassium. No boron, copper, nitrogen or phosphorus.
