De nada.
I owe ya for my education.

About burning the roots.
I have a fogger in my koi pond.
When the Lilly pads float across the emitter it burns track in them.
Here's a snap of a lilly pad that got in it's way.
Sliced it like a laser.

Does not seem to bother the guppies.
Bet the little stoners are suckin' on the blue lotus rootlets.

Mebee try a bold experiment.
Finger dat fogger!
If you finger no like, roots no like.

Keep talkin' to yo'sef.
Lotta lurkers listnin'.

Regards
