The thing I found most interesting is that all tanks experienced a similar level of nitrate reduction- shallow or deep substrate.

It made me re-think the value of plenums and DSBs. I fact it should make us question what we think we know about how nitrates are reduced in our aquariums. Nitrate is obviously being reduced in areas other than anoxic zones

That is pretty interesting.

*puts on thinking cap*

... Okay, that wasn't a good idea, I'm going to bed now, LOL!

Later.
