Tom, I would like to read up on those papers. Please PM me or post them here. Thank you.

I have heard of and understand the logic of macros in the substrate in lower light tanks and using root tabs for heavy feeders under low/high light. What I really don't understand is why some folks, whose opinions I highly value, insist that macros in the substrate is crucial when dealing with high light setups. Is the benefit of the lower redox values lead to such significant difference(s) as to warrant its use?

If macros are so important in the substrate, then is there some product or DIY procedures that make macros safe and conducive for the application in question?

Sorry if I have strayed from the original topic Art.
