So, I am trying to figgure out if I should get root tabs, or liquid ferts in a sand substrate. The sand is CaribSea Super Naturals, if that matters. It's pretty fine.
The plants are amazon sword, crypt wendii, dwarf hairgrass, and moneywort for now, although I plan on getting more.
I can't seem to find anything about how ferts work with sand, just gravel, so maybe it doesn't matter?
I just know most of the waste to provide "food" mostly just stays on the top, so I am afraid root tabs won't spread since they say to not put them right by the plants.
