I just planted and filled it yesterday. I'm currently using an Aquaclear HOB while I wait for a chance to order a new disconnect for the Eheim. CO2 hasn't even been set up yet. As you can see, the glass is still dirty and the water's a bit cloudy.
I'm using re-reused Eco-Complete that is now going on its 3rd tank. I basically cleaned it like you would Fluorite or 3MCQ. So it doesn't have any of the original nutrients it had out of the bag. But after draining the last tank, and scooping it all out, there was a lovely puddle of gooey organic matter (snail poop and mulm?) that I collected and applied as my thin bottom layer on the new tank.
So I'm starting with a little bit of organic goodness in there to get things going.
Stay tuned for better pics after things are all cycled and the CO2 is going. I'm not sure yet what I'll be stocking the tank with just yet, but I'm open to suggestion. Maybe some killies?
