I'm with Leigh. I don't get root rot on any plants, stem or otherwise. Stem
plants are seldom in the Flourite more than a month anyhow!

I researched UGF for planted tanks way back when I started mine. George Booth
had a great slide in one of his presentations: "This (lush) tank dispells the
myth that plants can't grow with a UGF." Then he explained how he only had to
break down the tank every 6 months to untangle the roots!

I decided UGF wasn't for me.

You can read my post on the APD of RFUG's using CPVC piping(Smaller
than regular PVC). These never get tangled, clogged and grow plants
excellent.
This style of UG also works very well with the finest of sands and
cost about 5-10$ for most any size tank.

But you don't need it, flourite+ peat and mulm does the trick much
better.
