Flourite for small-root plants?
I have Flourite as the only substrate in both of my tanks and have noticed that the smaller rooting plants seem to have difficulty holding onto the bottom. Specifically, my HC does not want to spread much at all and ends up uprooted by very small disturbances, much like the micro sword planted in the tank.
Is this issue common of Flourite? I am looking into getting some black Cichlid sand or similar product to top off the Flourite with in hopes of making the small roots take hold easier.
