Yesterday I purchased a bad of Petco black sand that I was planning on using but I've been reading alot of mixed comments on sand. So I was wondering is sand OK to use in a planted tank? I'm going to be using diy root tabs and ferts. But no co2 except a co2 booster. So I just want some input by the planted tank experts. Thanks in advise.

Could be more info on it but I think it's loosing favor for a cap because the smaller
grains tend to filter down into the dirt more. But I do know a couple of people who
use just sand(pool filter sand) as a sub/w Osmocote+ capsules for one of the people and
no tabs/capsules for the other person and their tanks look very nice and the plants are
just as good looking as any tank.

Root tab's with sand can work well, and many folk's use it with good result's.
I might make or purchase root tab's that contained product such as Osmocote, for many of the commercial root tab's are mostly Iron, and these alone may not provide enough in the way of macro nutrient's for good/better growth IME
