Wells here's a little update...
It appears I was a little hasty putting the driftwood in before it was fully soaked. My water was getting so dark and tannin stained. So, as much as I love that piece of wood I've taken it out and it is back in the 5 gallon bucket for some more soaking. This time I'm going to leave it for a couple weeks. I do plan to put it back in.
Meanwhile the anacharis has grown and is sending out some kind of long, thin stringlike roots maybe? They hang down from about halfway up the plant. The other plants are slow growers and haven't changed much except I've noticed the crypts have tiny baby leaves sprouting up from the sand. Also, my snail seems to have taken a liking to the crypts and a few of the leaves are munched on. But he leaves the other plants alone.
Today I added 3 more Harlequins.
Here's how the tank looks now (before the addition of the new fish).
You can see the water is still quite stained. A few more water changes should clear it up. I debated to put carbon back in to help clear it up but will this take the nutrients away from the plants? I've been using Flourish once a week.
