Small bags I think I might be short. Can I use something on the bottom layer? Maybe black sand?
You can absolutely layer the bottom with something fine grain and it will stay on the bottom. Some kind of sand or Black Diamond if you wanted a cheaper option esp since the ActivFlora is so black, the black diamond wouldn't look off underneath if any got pulled to the top.
I received my substrate today. I was still on the fence with whether or not two bags would be adequate for my 20 Long, and to my delight it is perfect for my needs as I only plan on having foreground and moss in this shrimp tank. I didn't have to dip into the substrate bags I purchased for my 40B which is great.
Just some pictures. Substrate slopes slightly from left to right. 2.5" to 2.1" in depth. I don't plan on filling the tank for a while as I want to shred some fissidens and dry start some drift wood and lava rock. I will update on thoughts when I get around to doing it.
Substrate is jet black, and I love the look. Prettiest plant substrate I've seen to date.
Setup includes a few ounces of laterite on the bottom layer, osmocote plus, flourish tabs for some of the nutrients lacking in the new osmocote, and BW Bebi through the substrate which is why the top layer has a brown sprinkling.
Fissidens on rocks and wood
Java moss on cholla wood
christmas moss on pebbles

Still loving the substrate. Best I've used so far, but time will tell.
Needed to remove Blyxa from the grow out tank since it was taking over so I moved up my time frame for filling the Activ-flora tank. Luckily the Fissidens took to the dry start fairly well and about 60% had stuck to the rocks and wood.
This is a few minutes after filling the tank. Almost no cloudiness.
