Chicken, did you use a dry start or not for the HC to get established in the soil? I just noticed it looks like you used normal type Amazonian (or a substrate with similar sized granules). I wasn't planning on doing a dry start and am wondering if I should add a layer of power type soil to help the groundcovers stay put while the roots develop a foothold.
No, I did not use a dry start for the HC. I planted with just a little water in the tank, filled it carefully, and it did fine. There was the occasional stem or clump that wouldn't stay planted at first, but it wasn't a big deal.
In the long run, the dry start wouldn't have been all that helpful to me. After awhile, the HC would grow into such a thick layer that it worked best to pull it out and replant it. So a dry start might have worked well when setting up the tank, but not for subsequent plantings.
Thanks for the compliments on the tank.
That was from a few years ago. It looks like this now: 2.5g yellow shrimp tank
