Thanks so much for the encouragement, guys. I'm blushing Steven, goodness!
slickwillislim -- Thanks for the heads up. That's something I had forgotten about, actually. This also being my first time using AquaSoil. I'm keep a close eye on the levels. I'm hoping that the masses of mulm and established substrate and filters will help stay on top of any spikes. I also use my Roseline barbs as one of my universal gauges of tank-health. They are pretty blatant about their "feelings."
While I'm disappointed that the wood floated because I had it sinking for a few weeks, I'm ok with the fact that it's buoyant right now because A) I have my tank back!! and B) Everything is so disheveled that it doesn't really matter, I need to get my ducks in a row and create a plan.
Since previously, my tank was a hodge-podge of unruly stem plants, I would like to go the lower-maintenance route this time and try to focus on just a couple nice accent stems and lots of Crypts, Anubias and Ferns. I STILL have my heart set on L. aromatica, so that's going to happen
So, once I have a budget in place and things are settled, HC, Downoi, mosses, Crypts and ornamental stems will be on my purchase list.
