I imagine the Eco-Complete would be very good, too, but less history there ...
history in my eyes, not that it isnt good substrate...because it is... but because #1... my plants like Eco-Complete better!
There was amazing differences in root growth between flourite and Eco... the reasons why this is I just have no explanation for because on the Eco bag the "ingredients are general" ... but I tell ya the results are visible.
When I recently moved into my new house and broke down my tanks it was amazing to me to see the diferences between the root systems of "Same Variety Plants" in the 2 substrates.
One with Eco and sand, the other with Flourite and sand but uprooting was completely different ! :shock:
And #2 reason for Eco, even if all else was equal... well, it isnt "red". :lol:
You can use a cover substrate or sand over Flourite but the dang "red" eventually comes out at some point in time through uprooting and settling. Im just sick of red I guess... heh
The Tahitan moon sand when "mixed in" really adds a nice flare to the color of the Eco and also helps hold very fine rooted plants easily.
Eco-Complete is a bit more "coarse" in size then is Flourite I have found which I imagine might pose problems in 100% form but I have never tried it myself so this is just an observation. Maybe others that are using 100% Eco as a substrate could elaborate.
But any future endeavors will be using Eco-Complete in my house
